And so, dear reader, on to the business of planting bulbs for our delectation next year.  For best results, it’s all about contemplation, location, preparation.  A random scheme? Now, where would be best for that?  But, then again, surely tulips look better in a more formal arrangement?  Perhaps in the cleared beds behind the greenhouse.

IMG-20181105-WA0010.jpg

Maybe.

But we are getting ahead of ourselves…..first, our plant ident. for the week:

IMG-20181111-WA0012.jpg

And good to see that at least one member of Friday Group is paying close attention.

Cotoneaster horizontalis

20181109_115636.jpg

20181113_132628.jpg

This is a spreading, deciduous shrub, familiar at this time of year due to its vivid, small red berries and regular, herringbone-style branches.  Its small, glossy green leaves turn orange and red in the autumn months, before dropping.  Birds love the berries and broadcast the seed around gardens, resulting in plentiful seedlings.  It is, in fact, a bit too successful for its own good, and has now been placed on the Schedule 9 list as “an invasive non-native species”.  However, provided it is kept under control, it is a useful shrub providing year-round interest; in spring, for instance, it is covered with small pink-tinged white flowers which are a magnet for bees.  Drought-resistant, low maintenance and good as ground cover, it is particularly useful on banks and slopes.  If grown against a sunny wall, it will grow upwards to about 2 metres.

Jasminum officinale affine “Fiona Sunrise”

20181109_115937.jpg

A beautiful, rampant climber which bears scented white flowers over the whole summer.  The stem and leaves are rather architectural, and the large leaves transition from vibrant yellow to orange/gold in the autumn  Attractive to bees, it is an excellent choice for growing up pergolas or fences.  Best grown in sunny, sheltered positions

Vaccinium  corymbosum

20181109_121204.jpg

Very much basking in its celebrity status as a “super fruit”, (it’s full of antioxidants), the blueberry needs an acid soil to grow successfully.  Acid soils are those with a pH level below 7.0 and, according to the R.H.S., blueberries need a pH of 5.5 or lower to thrive.  (You can measure the pH level of soil in the garden with a soil testing kit.)  Blueberry plants respond well to being cosseted in leaf mould.  If you have alkaline soil, they can be grown successfully in pots (use ericaceous compost), and should be fed with a liquid fertiliser for lime-hating plants.  They should ideally be watered with rainwater, as tap water will raise the soil’s pH level. Some varieties are self-fertile, but others require a different cultivar to be planted nearby for pollination.  A lovely, easy plant whose leaves seem to catch fire and glow in the autumn.  Oh, and delicious fruit, of course!

Three trees to look out for, especially at this time of year:

Ginkgo biloba

20181109_115837 (1).jpg

Otherwise known as the maidenhair tree, it is sometimes referred to as a “living fossil” because it is one of the world’s oldest living tree species.  Native to China, it has apparently been found in fossils dating back over 270 million years.  “Biloba” means “divided into two lobes” (easily visible in the above photo); over the centuries, the ginkgo’s leaves have been highly prized for their medicinal properties.  In the autumn they turn a glorious butter yellow before falling.  The trees are “dioecious” – which means that the male and female reproductive organs are on separate trees.  So for pollination, (by the wind), both a male and a female tree are required.  They can grow to 40 metres in height, but smaller varieties are available and can be grown in pots.

Prunus “Tai-Haku”

20181109_120058 (1).jpg

“Tai-haku” means “big, white flowers”.  Known as the Japanese great white cherry, this sensational, deciduous tree revels in pure white blossom in the spring and provides glorious colour in the autumn.  The specimen at Garden House stands in the top garden and has been there for 18 years; Bridge rates it highly.  Prefers full sun and reasonably fertile, well drained soil.  A.G.M. (Award of Garden Merit).  Between 4 to 8 metres tall x 8 metres plus in width.

Malus “Golden Hornet”

20181113_131901.jpg

A beautiful tree for a small garden.  This crab apple has lovely white spring blossom, and goes on to produce delightful clusters of small yellow crab apples in the autumn, which last for a long time on the tree. A nicely shaped, small, self-fertile tree, it can tolerate a range of soil types.

Jobs for the week:

Planting bulbs in pots for outside display 

IMG-20181111-WA0003.jpg

The fabulous blue Scilla siberica are going into this one.  Note those pots in the background – beautifully top-dressed with horticultural grit. 10/10, ladies.

Plant Hyacinth “Woodstock” around the rhubarb plants 

IMG-20181111-WA0004.jpg

They need to be planted around 10-15cms deep.  Their deep magenta/purple blooms will look beautiful alongside the forced rhubarb’s pink stems.

Sweep, tidy and refashion “Little Dixter” 

IMG-20181111-WA0016.jpg

Ensure that all tender perennials have been removed and cuttings taken.

Cut back geranium macrorhizum in beds under arches.  Plant alliums in and around the nepeta

IMG-20181111-WA0007.jpg

Yes!  That jacket is exactly the sort of colour we hope to achieve next year with the allium /catmint combo.

Plant chionodoxa bulbs randomly in prepared bed

In position and looking good.

Lay out wallflowers in Lil’s bed ready for (random) planting

20181109_121239 (1).jpg

Wallflowers are biennials: foliage this year, flowers next year.  Plant firmly and deeply then pinch out the top to ensure a bushy (not leggy) plant.

IMG-20181111-WA0011.jpg

Tulip bulbs will then be thrown over the bed and planted where they land.  Here’s a (literally) hot tip: sprinkle chilli flakes over the soil to discourage squirrels from plundering bulbs.  That’ll teach the blighters.

Formal planting in the beds near the greenhouse

IMG-20181111-WA0008.jpg

Wallflowers planted first – about 45 cms apart – and deeply.

Scenes of industry and meticulous planning.

IMG-20181111-WA0009.jpg

Lay out bulbs ready for planting

IMG-20181111-WA0000.jpg

Using string ensures straight lines for formal planting arrangements.  Plant around 10 cms apart and at least twice the depth of the bulb.  Some say it’s better to plant even deeper. If you garden on heavy clay soil, putting a layer of grit into the planting hole helps to prevent the bulbs from rotting.

Friday 2nd November 2018

We are back after a break for half-term, and the temperatures are dropping.  But not our spirits.  Blue sky, sunshine and the prospect of fireworks this weekend – what’s not to like?

IMG-20181105-WA0000.jpg

Just before our regular plant identification session, Bridge drew our attention to a recently published book, “Botanical Illustration” by Leigh Ann Gale.  A leading botanical artist and tutor, Leigh Ann regularly features on courses offered on the Garden House website.  Especially exciting is the fact that the book includes illustrations by Vicky Sharman, an erstwhile Friday Group stalwart and all-round terrific gardener. Congratulations, Vicky!

Plant ident. 

The topic this week is – shrubs.  Here at Garden House, we love a good shrubbery  – very much like Monty Python’s knights who say “ni”.

Fatsia japonica

20181107_173614.jpg

Such a useful stalwart planted in a shady situation.  It also looks stylish in a black container. Dark green, glossy, architectural leaves which are a matt soft green on the reverse.  If it gets leggy, just prune it back in the spring and it will respond well.  At this time of year it produces small umbel-like flowers, which Alan Titchmarsh has described as looking like tiny exploding fireworks. How appropriate!

Choisya ternata

20181108_094310.jpg

Best in full sun, the Mexican orange blossom is an evergreen shrub which produces star-shaped, scented white flowers in the summer.  A popular plant, often used in city plantings as it is tolerant of pollution.  If pruned after spring/summer flowering, you may get more flowers in the autumn.  A more compact alternative for smaller gardens might be Choisya “Aztec Pearl”, with much slimmer leaves.  Choisya ternata “Sundance” has bright gold/yellow leaves.  This last one is a bit of a Marmite plant; you either love it or hate it.  Here it is:-

20181108_094444.jpg

Rosa Frances E. Lester

20181102_122126 (1).jpg

Not a shrub, admittedly, but lovely at this time of year.  A wonderful, fragrant, rambling rose, with strong, bushy growth.  It has masses of small single blooms in the early summer and, if left unpruned after flowering, it produces small vivid red hips in profusion in the autumn. Such a great rose, it well deserves its Award of Garden Merit from the R.H.S.

Hebe

What you might call “a good doer”, this is a very diverse genus of plants, largely native to New Zealand.  They are valuable evergreen shrubs, mostly fairly compact, and are pretty tough characters.  Particularly good in seaside gardens, they like full sun, and are available in a range of colours from white, pink, through to shades of mauve and purple. They can be pruned hard back in spring, right back to a pair of shoots (but don’t cut into old, bare wood).  Softwood cuttings can be taken in the spring and should root fairly easily

Viburnum rhytidophyllum

20181107_174755.jpg

20181107_174911.jpg

 

 

The leatherleaf viburnum, with its deeply-corrugated, dark green leaves, likes full sun. Hardy, evergreen and easy, it is tolerant of different types of soil, although it does appreciate being sheltered from strong winds.       

Abelia x grandiflora

20181107_181040 (1).jpg

A good, reliable and long-flowering garden shrub, abelia is semi-evergreen with attractive, glossy leaves.  Rather lax in its growth, it has small, fragrant trumpet-like flowers produced on long arching branches from mid-summer.  Grow in sun, ideally in a sheltered position.

Lonicera “Baggesen’s Gold”

20181108_130142.jpg

This species of shrubby honeysuckle is particularly known for its use as a hedging plant, and is often used in place of box where a dwarf formal hedge is needed.  It can be planted in full sun or partial shade, but its evergreen, oval, yellow leaves become even more golden in the sunshine.  Another tough plant that tolerates a range of soils.

Griselinia littoralis

20181107_180003.jpg

Originating in New Zealand, this shrub is a tough cookie – and another good doer.  Often seen grown as a hedge, it can tolerate salty conditions, and is therefore an obvious choice for coastal gardens.  It responds well to clipping and can be propagated by taking cuttings.

Buxus sempervirens

boxwood-370547_640.jpg

Box.  Used in so many English gardens through the ages, it is the perfect plant for topiary (well, it was until the scourge of box blight took hold).  Its small, glossy green leaves can be clipped and manicured into balls, cones and hedges – but a fair degree of continuing maintenance is required to achieve perfection!  Perhaps a couple of box balls grown in a pair of elegant terracotta pots would be sufficient?  Can be grown in sunny or shady conditions.

Prunus laurocerasus 

20181108_104125 (1).jpg  

Also known as English laurel and cherry laurel, this is a fast-growing evergreen species of cherry.  Arguably, it’s best given a lot of space so that it can grow unimpeded, showing off its handsome. long, glossy leaves and, in spring, its white candle-type flowers.  Frequently used as a hedge in suburban gardens, it is fairly drought resistant.  Good as a windbreak.

And now for something completely different….

IMG-20181105-WA0012.jpg

The time for planting indoor bulbs has come.  Narcissus papyraceus “Ziva” (paperwhites), N. “Avalanche” (see above) and N. “Grand Soleil d’Or” make lovely Christmas centrepieces or gifts.  They take around six weeks to come into flower – and what you do is this:-

Take a bowl or possibly even some jam jars; drainage holes aren’t essential here.  Put some horticultural grit or a little polystyrene in the bottom.  Then fill either with grit or a mix of grit and compost. You could use decorative glass.  Plant bulbs with their tops showing – odd numbers work best.  If you like, finish off with horticultural grit or moss as a top dressing.  As the bulbs grow, you can add birch twigs to support them and this adds to the decorative effect.  The bowl needs to be kept somewhere cool and frost-free, but definitely not in a warm room, as they need to grow slowly for best results.  Keep soil just moist.  Then, hey presto!  Your family and friends will be well impressed.

20181102_104247.jpg

As they grow, the bulbs will straighten up.  Let’s check this out from above.

20181102_104132.jpg

There we are.  See you in six weeks time.

Jobs for the week:

Dig up dahlia tubers, wash off mud and leave to dry off for a couple of days.  These will be stored in perlite in crates and kept very slightly damp and frost-free in the shed.  It’s important not to let them dessicate – but equally they mustn’t rot off.  No pressure then…

IMG-20181105-WA0001.jpg

 

20181102_124014.jpg

Well-washed and drying off nicely.  Can’t say the same for the gardeners, unfortunately.

Dig up remaining salad crops from outside beds – making more space for planting out tulips in the coming weeks.

IMG-20181105-WA0002.jpg

Now that’s what I call a salad bowl.

Work on the new fruit bed – remove remaining annuals and Salvia uliginosa

Continue programme of autumn lawn care.  Complete lawn-spiking, then brush in a top dressing.  Scatter some grass seed to improve the lawn.

IMG-20181105-WA0004.jpg

IMG-20181105-WA0006.jpg

Note the carefully measured areas – ready for the right amount of top dressing

Put the bananas in pyjamas.  The Musa is cut down to about 30cms, put into a plastic pot filled with compost, then wrapped with fleece before storing it in the frost-free greenhouse for overwintering.

Sempervirens plants need re-potting and put under cover for the winter.   They can cope with lower temperatures but hate getting wet.

IMG-20181105-WA0008.jpg

These two hate getting wet too.

Prick out and pot up orlayas and other hardy annuals

IMG-20181105-WA0007.jpg

Splendid!

Enjoy your bonfires and fireworks.  Keep safe!

 

 

 

 

 

 

 

 

 

 

Friday 19th October 2018

20181019_114434.jpg

The season of mists and mellow fruitfulness is upon us, and with it come squashes, pumpkins and gourds in all shapes and sizes…. I mean, look at this extraordinary creature –

20181019_114605.jpg

Impressive

We looked briefly at hardy annuals (sown, flower and die in a year) again this week.  Hardy annuals can be sown now – up until the clocks go back – and then in March/April next year.  Examples are: scabious, marigolds (Calendula officinalis), ammis, sweet peas (Lathyrus odoratus), wild carrot (Daucus carota), cornflowers (Centaurea cyanus), Californian poppies (Eschscholzia californica), false fennel (Ridolfia segetum), corncockles (Agrostemma githago) and the white lace flower (Orlaya grandiflora).

H.a. seeds need a warm place to germinate, so, once sown in modules or pots, a small electric propagator is an ideal environment for them.  At Garden House we put seeds in the greenhouse on a heated mat (see below), but you can try them indoors on a sunny window-sill.

20181019_124819 (1).jpg

They need light to grow; once the seedlings have been potted on and hardened off, a cold frame is perfect for overwintering – open in the day for ventilation, but closed at night for protection.  (Its worse than looking after children.)  The seedlings’ growth slows as winter takes hold, but, come next year, these autumn-sown plants will be bigger, stronger and garden-ready earlier than their spring-sown counterparts.  It is possible to direct-sow some hardy annual seeds successfully into autumn’s still-warm soil, (e.g. nigella, marigolds and cornflowers) but for better control, we tend to opt for protected sowing.

The tender perennial cuttings (such as Plectranthus argentatus), taken at the end of September, have already started rooting, thanks to the gentle heat provided by the soil warming cables in the greenhouse. They must be kept frost-free if they are to survive the winter – maybe in an insulated greenhouse, a conservatory or perhaps in a cold bedroom. The cuttings will be potted on into FP9 pots using a 50:50 mix of compost and perlite.  Topping with horticultural grit helps with drainage, reduces weed growth and acts as a deterrent to slugs and snails.  Looks nice too.

20181019_114535.jpg

Can’t see any horticultural grit topping here though……

Streptocarpus cuttings

20181019_114309.jpg

These indoor beauties can be propagated from leaf cuttings.  It’s a miracle!

Mid-rib method: Take one healthy leaf. Place face down on a board. Using a very sharp knife, run the blade down either side of the rib which runs from top to bottom. Take out the mid-rib completely – and two lengths of leaf remain. Place them upright (on edge with cut side down) into a 50:50 mix of compost and perlite.  Firm in and water.  Each vein should produce an offset, which will eventually become a new plant.  Place somewhere warm (in a propagator or on a sunny window-sill with a clear covering over). Try a plastic shower cap, if you’re feeling funky.

Lateral vein method: Take another healthy leaf.  Place face down on board. (So far so similar.)  Using a very sharp knife, cut laterally across the leaf; depending on the length of the leaf, you can get about four cuttings.  Place upright into the compost mix, remembering to put the cut edge downwards. Firm in. Water.  One offset should grow from each cutting.

IMG-20181023-WA0003 (1).jpg

Mid-rib cuttings at top; lateral vein cuttings below

Fingers crossed – and let’s hope they’re green fingers too.

Plant Ident. 

This week’s ident. looked at autumn delights such as these astonishing

Nerine bowdenii

20181019_114814.jpg

A surprising colour at this time of year, these plants originate from South Africa and come in shades of pale and dark pink as well as white.  They love to bake in full sun and do well near south-facing walls; they should be planted with their top halves proud of the soil.  Bulbs can remain permanently in the ground once planted, as they can withstand freezing temperatures. They do need good drainage, however, and don’t like to be disturbed.

IMG-20181022-WA0001 (1).jpg

Also looking magnificent in the garden now is the ubiquitous, but nonetheless valuable

                                                              Fatsia japonica

20181019_115317.jpg

and one from the back, please…

20181019_115410.jpg

…thank you

Also known as the false castor oil plant, Fatsia japonica is a handsome, evergreen shrub, noted for its beautiful, architectural leaves – dark, glossy green on the front contrasting with matt, soft green on the underside.  Fatsias thrive in a shady position and respond well to being cut back and shaped as required – they grow back easily.  Any yellow/ brown/ blackened leaves can just be removed.  Odd, creamy-white flowers appear at this time of year, reminiscent of those produced by ivy.  Also good in large containers.

Viburnum rhytidophyllum 

20181019_115012.jpg

The evergreen leatherleaf viburnum gives year-round colour and interest in the garden.  A tough, drought-tolerant plant, producing red fruit at this time of year, and small, fragrant white flowers in the spring.  It has striking, deep-green, corrugated leaves.  Plant in full sun.

Clerodendrum trichotomum

20181019_114649.jpg

20181019_114710.jpg

This is a vigorous, deciduous shrub whose starry, white flowers, produced in the summer, are highly fragrant.  They are followed by amazing metallic turquoise-blue berries held in crimson calyces – an arresting sight. When crushed, the leaves of this shrub are said to smell of peanut butter.  Grow in full sun or partial shade.

Symphoricarpos albus 

20181019_114634.jpg

Snowberry’s white, waxy berries look well in mixed shrub borders in the autumn and early winter months.  They are preceded by small, pink flowers in the summer.  A suckering, deciduous shrub from the honeysuckle family, snowberry can be grown in both full sun and partial shade – plus it tolerates exposed sites, pollution and poor soils. One tough customer.  There are varieties with beautiful pink berries.  Sought after by florists – and definitely a good bet for gardeners who don’t have green fingers..

Jobs for the week:

Friday 12th October 2018

IMG-20181014-WA0016.jpg

Today we started with a fascinating talk given by Judy McClelland, who runs “Flowers from the Field” in Isfield.  Bringing with her a jewel-like selection of late-summer blooms, she explained how to grow cut flowers for the home – and shared with us the best varieties to choose, how to cut and condition your flowers and the secrets behind keeping them looking fresh for longer.

20181012_112020.jpg

Inspired by the flowers she saw whilst working in the Netherlands, Judy followed her passion and eventually found a plot of land near Lewes, where, in recent years, she has literally reaped what she has sown. Fighting the elements has been challenging, but photos of her raised flower beds and polytunnel were clear evidence of her success.

The how:  It’s important to think about the site; a wind barrier is a good idea if the area is exposed.  Sunshine, good soil and good drainage are essential – Judy uses green compost and horticultural grit to open up and improve her clay soil.  Green waste (recycled compost) is also used as a mulch around the plants, which acts as a weed suppressant and retains moisture. Cut flowers don’t need a lot in the way of nutrients – only the sweet peas and dahlias are given a tomato feed.  Staking is crucial; Judy finds horizontal netting over the plants invaluable and has it in place before everything starts to grow up through it.  Her polytunnel enables her to get a head start on growing things like sweet peas.

More details:  Most of her plants are grown from seed, which is cheap to buy.  She sows into modules to have better control over the seedlings.

20181012_124306.jpg

Only a few are sown direct (e.g. ammis). Hardy annuals can be sown now, but she sows most in Feb/March.  The half-hardy types are sown in mid to late April; fast growers, they like warmth, so don’t sow too early. (Judy doesn’t have a heated propagator but does use a cold frame.) Light is essential to growing good healthy plants. A cutting patch of 1 m wide x 2 m long takes about 18 plants, with around 30 cms between each plant. More space results in better and bigger plants.  Weed and water and pray for clement sunny weather.  Beware pests! Especially our old friend –

Close-up Photography of Snail

Tips on cutting and conditioning:  Get to know your plants.  Some need to be picked at just the right point in their life cycle.  For example, scabious will carry on maturing, so need to be picked before they are fully open.  Others, like dahlias, don’t open further after picking – their buds remain as buds.  Pick flowers in the early morning, ideally after the dew has gone, but before the heat of the sun affects the blooms. Once cut, remove leaves from the stems, cut the base at an angle and plunge them straight into a bucket of cool water.  Leave for a couple of hours or overnight in a cool place before arranging.

How to keep your flowers fresh:  Bacteria spells death for flowers!  Ensure your tools and vases are spotlessly clean (a little drop of bleach in the water can help).  Change the water completely every couple of days.

20180901_102428.jpg

A few of Judy’s must-have annuals: 

Salvia viridis, or Clary sage.  A hardy annual that self-seeds. Judy recommends the blue and pink varieties.

Centaurea cyanus, or cornflowers – especially Blue Boy and, even better, Red Boy.

20181012_124749.jpg                                                                                                                                     20181012_124949.jpg

Top picture:  Zinnia “Dahlia-Flowered Mix”. Bottom:  blue Salvia viridis, the acid yellow/green of Euphorbia oblongata, Sedum “Herbstfreude” and zinnias. 

Zinnias –  half-hardy annuals; especially the “Dahlia-Flowered Mixed” collection.  Good stiff stems.  Cut the flowers above a leaf node and deep on the stem to encourage regrowth.

Consolida ajacis, or larkspur – highly recommended – also thrives on being cut. Judy likes the varieties “White” and “Dark Blue”. Its seeds germinate better after a cold spell (“vernalisation”). Top tip: dampen a piece of kitchen paper; place some seeds on it; fold over; seal in a plastic bag; place in freezer for a week; take out and into a warm place; sow.

Antirrhinums, or snapdragons; another cut-and-come-again plant. Use tall varieties, like the white “Royal Bride”.

Tithonia “Torch” – although she finds their flower heads can flop in the vase.

Ammi visnaga “Green Mist” and “Casablanca” – they form good “chunky” plants which branch well.

Malope trifida “Vulcan” – a good, tall annual which lasts well in a vase.

Daucus carota – the wild carrot, (biennial).  Beautiful – should be sown direct.

Ageratum “Blue Horizon” and Timeless Mixed”.   

Euphorbia oblongata – a fantastic “filler” in flower arrangements.  But, be careful of the white, milky sap which is an irritant to the skin and eyes.

Judy completed her talk by demonstrating how to arrange a hand-held bunch of flowers using annuals, perennials, shrubs, herbs and grasses.  Odd numbers work well.  She made it look easy, but we know it’s all down to magic.

Jobs this week: 

It’s autumn, and it’s all about preparation.

HARVEST.jpg

Autumn is upon us: crisp days and earlier nights.  At Garden House we are enjoying the harvest and delighting in the dahlias… and thinking about the bulb programme for the year ahead.  Nothing stands still here.

IMG-20181007-WA0016 (1).jpg

Our plant ident. this week focused on the flower of the moment, the dahlia.  It’s amazing to think that something so beautiful can grow from such ugly root tubers.  We looked at their many shapes, sizes and colours – from single to ball to cactus and beyond.  They have come back into fashion in recent years, and are now much prized by gardeners and florists alike.  Sometimes elegant, sometimes blowsy, their presence is invaluable in both vase and garden, providing colour and interest from late June through to the frosts.  They belong to the Asteraceae family and are tuberous, tender perennials.

Tubers can be potted up in February (in a heated greenhouse) and stem cuttings can be taken as they come into growth. (These will not flower until the following year.) Meanwhile, the potted tubers will have become bushy plants and can be planted out once all danger of frost has passed, usually in May, at a depth of about 20-30 cms.  Dahlias flourish in rich, fertile well-drained soil in full sun.  They are hungry plants and benefit from good well-rotted compost and a scattering of fertiliser when they are planted.  Slugs love them – so take precautions – and they also require staking with bamboo sticks or similar to prevent them flopping over.  Once flowers appear it is advisable to give them a liquid feed every couple of weeks, as this will encourage more flowers – as will pinching out the main growing shoot to just above a pair of leaves.  Don’t forget to deadhead too!

As dahlias die down  in November they should be cut back.  At Garden House we dig up the tubers, and store them in a frost-free, airy environment, keeping them slightly damp so that they don’t dry out completely.  This leaves the ground free for further planting schemes. Some gardeners, however, leave dahlia tubers in the ground to overwinter – covering them with a bucket of mulch.  It is said that this promotes more and better flower growth the following year – as long as winter wet doesn’t kill the tubers.

High maintenance they may be, but dazzling dahlias definitely repay the effort put in.

Dahlia ‘Bishop of Llandaff’

BP. OF LLANDAFF 420181005_125952.jpg

This vivid red peony-flowered dahlia, with its contrasting dark stems and foliage, is a favourite of bees and other pollinators; it holds an R.H.S. Award of Garden Merit

Dahlia ‘Jowey Mirella’

JOWEY MIRELLA.jpg

A dramatic ball dahlia; its long strong stems make it wonderful as a cut flower. Ball dahlias are prized by flower arrangers for their perfect round flower heads and their clear colours.

Dahlia ‘Tahoma Moonshot’

20181005_131358.jpg

This stunning Honka variety has deep burgundy, velvety, single flowers  with a rich  yellow centre.  Attractive in growth, Bridge finds that it is not particularly good as a cut flower as the petals tend to fall.

Dahlia ‘New Baby’

ORANGE BABY 2.jpg

This little Pompon beauty may be small, but it is a real delight.  Good in hot borders and works well with dark red and magenta dahlias – such as……….

Dahlia ‘Chat Noir’

CHAT NOIR.jpg

A fabulous semi-cactus dahlia, with spiky garnet-red petals and a nearly black centre.  Dramatic in a tropical-style border.  And below is another semi-cactus dahlia –  again, it has a spiky flower head (magnificently magenta), but this one has petals which split at the end – like a deer’s antler.

Dahlia ‘Ambition’ 

DAHLIA AMBITION.jpg

And now, from semi-cactus to full blown cactus……….

Dahlia ‘Karma Bon Bini’

DAHLIA 'KARMA BON BINI'.jpg

A stunning bi-coloured dahlia whose inner petals are golden-yellow, turning to fiery red-orange on the outer layers. Spectacular!  And there’s more –

The Collerette-flowered Dahlia ‘Pooh’  – these dahlias have a little collar of shorter florets which surround the centre disc.

DAHLIA 'POOH'.jpg

Dahlia coccinea, a delightful single flowered species, loved by bees.                                                                                                            COCCINEA.jpg

Jobs this week:

  • Continue to clear beds of eschscholzias, ammis and self-sown grasses
  • Label all the various dahlias in the garden so that when lifted, we will be able to correctly identify the tubers as we prepare them for winter storage.

IMG-20181007-WA0005.jpg

I think that’s actually a cosmos you’re looking at ……..

  • In the greenhouse, check progress of recently sown seeds.  (Looking good.)

IMG-20181007-WA0013.jpg

  • Pot on cuttings.  Good job!

IMG-20181007-WA0010.jpg

  • Take tomatoes out of the greenhouse. Plant up chrysanthemums for Christmas flowering

Friday September 28th

0cec3f6b-39b0-4bd8-bd2c-55a230c3aa33-e1538488561287.jpg

Today we chatted about which particular garden tool or piece of garden paraphernalia we really couldn’t do without.  The usual suspects came up such as secateurs/snips, brooms, garden clogs, a potting tray, trugs, dibbers, garden gloves, long handled loppers and so the list goes on.  Some of us are even lucky enough to own antique spades and forks which are especially cherished.  We particularly liked these pink steel capped boots; gardening apron with double holster(!) and mini snips – just right for when you accidently come across a stray stem of somethig gorgeous reaching out over a public footpath ……

We had a good discussion and demonstration from Bridge about how to take soft wood cuttings.  This method can be used for cultivating all sorts of perennials and shrubs as well as some trees.  It is usually carried out in spring and early summer but we are taking a chance now.  Other methods of taking cuttings are semi-ripe (autumn) and hard wood (winter) – we will talk about these another day.

Good plants to take cuttings from are herbs and tender perennials such as pelargoniums.  The best time to take soft wood cuttings is in the morning when the plants are full of water.  Look around the garden for suitable cutting material – it should be a healthy fast-growing shoot with short internodes.

  • Cut the stem just above a leaf node of the parent plant .
  • To prepare the cutting, cut the base of the stem 6mm below a leaf joint (this is where all the growth hormones and energy are stored) so that the cutting is no more than 10cm in length.
  • Remove the leaves from the bottom third of the cutting to minimise water loss (from the leaves) and pinch out the flowering central tip from the top of the stem (apical dominance).  Another way of minimising water loss from the cutting is to cut any remaining large leaves in half.
  • Using a dibber, make a hole for the cutting in a container of compost (ours included perlite) and insert the cutting with the first leaves just above the level of compost.  You can usually fit 5-6 in each pot.
  • Label, gently firm the cuttings into the compost and water with a fine-rosed watering can.

A similar method is to take a heel cutting where you gently ease the shoot away from the main parent stem, taking with it a bit of the stem (the heel) as you go.  Neaten the tail on the heel by cutting across it with a very sharp knife.  Place the cutting in compost as before.

The compost should be kept moist to encourage root growth.  Bottom heat would help to produce the roots but if done before the weather gets much cooler, the cuttings should do well under glass, propagator or perhaps enclosed in a sealed polythene bag.

Good plants for taking softwood cuttings now:

Salvia officinalis ‘Purpurascens’

9b0556e611d7507bb064121d69b24f0349f1de59.jpg

This old healing herb was sacred to the Romans and remains an important culinary herb today.  Its young red-purple leaves look good in the border and should be well-clipped to maintain shape and encourage new leaves which have the best flavour.  It grows well in full sun/partial shade in light well-drained soil.  It will reach 80cm in height.

Santolina chamaecyparissus – cotton lavender

Unknown.jpeg

This rounded compact shrub has grey-green foliage which is aromatic when crushed.  During July and August, its yellow button flowers push up through the foliage on wiry stems.  It is perfect for a hot, sheltered border with poor-moderately drained soil.  It looks particularly good in gravel gardens.

Lavandula – lavender

WSY0078483_61495.jpg

This is another sun-loving plant which thrives in hot, sunny borders and gravel gardens.  It prefers poor-moderately fertile borders (or containers) and will do well in  chalky/alkaline areas.  If you garden on clay, add organic matter mixed with gravel to improve darinage and to prolong the life of the plant.

Teucrium chamaedrys – wall germander

Unknown-1

This low-growing plant can be either deciduous or evergreen in warmer areas.  It is mainly grown for its aromatic dark green foliage and produces pink-light purple flowers.  It looks good in containers, planted as low hedging, knot gardens, rockeries or as edging.  It prefers a sheltered site in full sun and should be cut back hard after flowering.

Jobs this week:

  • Planting Narcissi Thalia bulbs under the arches, along with apricot coloured foxgloves.

Many thanks to all of you who came to support our coffee morning last Friday to raise money for Macmillan Cancer Care.  It’s always good to welcome visitors into the garden and especially for a good cause.

Friday 21st September

More new faces and introductions continued with a discussion about what is our favourite garden of the moment?

Among others, there were many votes for the Sussex Prairie Garden which is possibly at its most beautiful now as the seed heads ripen and the autumn sun shines across the grasses.  However, it is striking how many of us nominated small private gardens which we pass by or visit on a regular basis.  It just goes to show that our favourite gardens don’t have to be huge spaces designed on a massive scale – gardens are very personal and speak to us all in very different ways.

To ease us into the morning, Mary read us an excerpt from Ambra Edwards’ book called “Head Gardeners”.  Jim Buckland and Sarah Wain are the couple behind the beautiful garden at West Dean College.  It was fascinating to hear how their joint passion for gardening has shaped the garden and how it has become so much a part of their lives.

As it is peak Dahlia season at the moment, it is necessary to keep dead heading regularly in order to prolong flowering.  To make sure you remove flowers that are dead and not buds which are about open, look for squishy, pointy flower tops which are the seed heads and need to be removed to concentrate energy into the emerging new flowers.  The picture below shows a spent flower head (right) and a new bud which is rounded and firm.

IMG_1053.jpg

Cut the stem back to the nearest leaf joint, so removing the apical dominance of the main stem.  This will extend the life of the plant.

The Plant I.D. today concentrated on grasses.  Valued in the garden for their texture, sound and movement and providing a long season of interest, it was interesting to focus on a few examples we have growing in the garden.

Pennisetum macrourum or South African fountain grass.

1477655025_7717.jpg

These sun-loving plants with their thin, spikey panicles are not totally frost hardy in cooler climates.  They grow in clumps and send out runners which go on to produce new clumps of narrow green leaves which turn yellow in autumn.  The flower panicles are produced in late summer/early autumn.

Hakonechloa macra ‘Aureola’

IMG_1063.jpg

These neat, clump-forming deciduous grasses have vivid green and yellow stripes, turning slightly red in autumn/early winter.  They do best in full sun although will tolerate partial shade.  Growing to 30cm, they look good planted in terracotta pots.  They will disappear completely during the winter.

Panicum virgatum ‘Shenandoah’ or swith grass ‘Schenandoah’

IMG_1060.jpg

These deciduous perennials are proper ‘prairie grasses’ and grow to 90cm in full sun.  Characterised by their blue-grey narrow leaves, these take on a reddish tinge in late summer.  The delicate flowers spikes are produced on tall stiff stems which last through the winter in clumps.

Panicum virgatum ‘Heavy Metal’

heavy-metal-1.jpg

These rhizomatous perennial grasses grow well in full sun and form clumps of upright blue-grey leaves which turn a reddish colour in autumn.  They produce weeping pannicles of purple-tinged flowers in late summer/early autumn.  In the right conditions they can grow up to a metre.

Pennisetum alopecuroides viridescens or Black Fountain Grass

IMG_1055.jpg

Growing to around 60cm, these are slightly smaller than the regular species and are a good choice for the smaller garden.  In late summer, the purple-black flower plumes emerge, contrasting well with the slender green leaves.  The leaves turn more yellow in the autumn and the seed heads provide a valuable food source for birds.  They prefer a sunny position and look great in containers.

Miscanthus sinensis ‘Morning Light’

IMG_1058.jpg

These are probably the oldest cultivated form of Miscanthus and originate from Japan.  Their leaves are slightly variegated but as a whole they give off a greyish effect.  In warmer climates, reddish-pink flowers are produced in late summer although in cooler areas they seldom flower.

When choosing grasses, check their growing conditions as some dislike growing in chalk which is tricky in our Brighton gardens!

Jobs this week:

  • Pot on hardy annual seedlings which have self-seeded, eg ammi and escholzia.
  • Pot on wallflowers into individual pots (adding chicken manure).  The tops were pinched out to remove the apical dominance and to make the plants more bushy.  These will be planted eventually amongst the tulips.

  • Major action in the compost heaps.

6a68edc9-cd14-46cf-aa0a-74c527d184f1.jpg

We are trying to keep to a strict toutine with the compost heaps and are continuing with the ‘traffic light’ system to organise the heaps in terms of readiness.

 

 

Green waste for the compost heap should only be placed in the green bin.  The amber bin is work in progress and the red bin is full of compost ready to be used.
