We started to think about bulbs to be planted in the garden with plans for  major bulb planting activities in the borders and in pots over the next few weeks. Erythroniums (dog’s tooth violets) will be planted in the newly created woodland garden as they can do well in shade or sun with moist soil. They are perennials which if left undisturbed in the same position will become well established.

It is also time to think about planting forced narcissus bulbs for indoor displays – such as Paperwhite or Grand Soleil D’or. They are both very fragrant and easy to grow, and will flower about 6 or 7 weeks after planting. They can be planted in soil and grit or even just water as the bulbs contain all they need for growth.

We also looked at some of the tulip bulbs that will be planted in beds and in pots. Tulips don’t need to be planted until November as the colder temperatures help to eliminate any viral or fungal diseases that may be in the soil and could infect the bulbs. If they are to be planted in flower beds then they can be put in holes up to 8″ deep. Deeper planting means they are more likely to survive from year to year. If the bulbs are to be planted in pots they can be planted much more densely just avoiding the bulbs touching each other in the compost. Two of Bridge’s favourites are the bright and vibrant Doll’s Minuet and the creamy Sapporo.

Wallflowers combine very well with tulips – they can be bought now in pots and divided or as bare root plants. Any bare root plants need to be planted out really within a day or so of purchase as the roots will dry out. If they can’t be planted straight away just put them in a pot with soil as a temporary measure. Wallflowers or Erysiums are part of the Brassicaceae family so they are related to cabbages. They are generally grown as biennials although Erysium Bowles Mauve is an evergreen perennial. It has grey green leaves and very fragrant flowers with a long flowering season and likes full sun. It can get rather woody after a few years but is very easy to propagate from cuttings.

We also looked at Elaeagnus pungens ‘Maculata’.  This is an evergreen shrub that is great in autumn or winter to lighten up a dark corner of the garden. It has bright yellow leaves outlined in green and has tiny white fragrant flowers in autumn.

Ceratostigma plumbaginoides or hardy plumbago is also a very beautiful autumn flowering herbaceous perennial. It has vibrant blue flowers and the leaves turn red or purple in autumn. It is great as an edging plant in borders and needs full sun.

This is also a wonderful time to put together your ‘autumn nature table’ and we looked at some amazing seed pods from tree peonies and also some crab apples from Sue’s Crab Apple ‘Red Sentinel’ which is a good tree for a small garden. Check out Sarah Raven creating an autumn wreath.

Late flowering perennials and ‘plants that die well’ was our focus for discussion today. Umbels are particularly good at dying well and provide wonderful structure in the border so think about what needs to be cut back and leave plants that still have architectural interest.

imagesX7ZAOG7W

Umbels are defined as ‘an inflorescence in which a number of flower stalks or pedicels, nearly equal in length, spread from a common centre’. They are often flat topped with flower stalks that are splayed like ribs on an umbrella. Examples of umbels are fennel, angelica, cow parsley, ammi, astrantia, flowers of carrots and parsnips.

Dixter 2 wild carrot

Lots of discussion about a recent visit by some group members to Great Dixter and how inspirational and extraordinary the garden is even in the autumn in the pouring rain. The plant identification featured some plants bought at their plant fair.

Plant identification:

  • Thalictrum yunnanense- a low growing clump-forming Chinese perennial  with upright slightly hairy slender stems to 60cm tall. It has whitish flowers, from tight pinkish buds. It likes full sun or part shade in any type of drained soil and will do well on chalky soil. Flowering July to August. Thalictrums are a genus of about 130 species and are part of rununculaceae family, common name is meadow rue. Most thalictrums are tall and excellent background plants in the border.

thalyunn

  • Begonia modestiflora- a hardy perennial that does well in shade. Begonias are a genus of about 900 species and many cultivars of fleshy annuals, perennials, evergreen shrubs and climbers including some succulents. (See picture of begonias in Ann’s garden)

begonia

  • Fuchsia  ‘Pumila’ is an upright, bushy, deciduous, compact shrub with  dark green leaves and throughout summer, small red and purple flowers. It is hardy and good for low hedging.

We discussed plans for the garden over the forthcoming year – there is still quite a lot of colour in the garden but when the flowers in cut flower beds are over this area will be used for vegetable growing. The bed at the back of the garden near the shed will be planted with shrubs and plants that thrive in shade will be planted under the cherry tree in top garden.

Salvia ‘Nachtvlinder’

We also talked about  salvias which are part of the lamiaceae family. The genus of salvias contains about 900 species including annuals, biennials, herbaceous and evergreen perennials and shrubs. They are usually grown in sunny sites and many are aromatic and most have distinctive square stems. They can be fully hardy to frost tender. Julia talked about the BBC Gardeners World’s 25/9/14 visit to Great Comp Garden, Kent which holds the national collection of salvias. Recommended as the hardiest for British gardens are: Salvia ‘Jezebel’ (bright red flowers ) and Salvia x jamensis ‘Nachtvlinder’ (dark purple flowers).

Plant identification:

Friday 26th September

The Garden House held a workshop on roses last Saturday which Cathy described as an inspirational day. Feedback from the day included a reminder that now is the time to prune ramblers and climbers. Rambling roses usually flower once whilst climbers repeat flower during summer and autumn although there are exceptions to this. Climbers also tend to have double flowers and ramblers look more like wild roses and are more vigorous. Climbers are best grown over arches and up walls and trellises whilst ramblers are best grown through trees. Both climbers and ramblers tend to flower better if they are trained as this promotes more flowering shoots. So in autumn stems can be bent into shape,tied and looped around arches or other supports. Ramblers can be pruned by cutting out old wood at the base (removing one in three of old stems) and fanning out the stems, climbers need the main leaders reducing and pruning back the side shoots to about 6″. It is from these side shoots that the flowers will grow. It is good to give the plants a boost after pruning by adding a mulch of manure and compost and feeding again in spring. One tip for planting a rose in a site where an old rose has been taken out is to dig a cardboard box sized hole and plant the rose in the box surrounded by lots of compost.

We also looked at some rose hips. Rosa rugosa can have white or pink flowers and can be grown as a hedge. Ramblers don’t need dead heading and have attractive hips.

Rosa pimpinellifolia has creamy white flowers and blackish hips.

Paul brought along a wonderful selection of plants that look great in the garden now including a number of asters. The purple/blue of asters combine very well with yellows and oranges of rudbeckias. Asters are very flexible plants for late summer and autumn with their foliage often looking good before the flowers emerge. They also flower for a long time. They like sun but can survive well in semi shaded areas.

  • Aster laterifloris horizontalis has stiff stems with small dark green leaves and tiny silvery flowers with pink centres. It looks lovely in naturalistic or more formal planting and can grow to 60cm.

  • Aster turbinellus has arching growth and grows to about 5’or 6′ feet tall. It can loose leaves lower down and flowers at the top so is good at the back of the border.

We had some discussion about our favourite plants or flowers at the start of the group. A favourite of Clare’s is Hesperantha or Schizostylis as they used to be called (common name is river lily). They are plants native to S. Africa and Zimbabwe and are great for late summer and autumn colour. They need a sheltered sunny place with moist but well drained soil. Plants can be divided every 2/3 years in the spring.

hesperantha

hesperantha 2

We looked at a range of bulbs. Now is the time to plant alliums outside and forced hyacinths for indoors if you want hyacinth flowers for Christmas. Other spring bulbs such as daffodils, crocus, muscari, tulips should be planted outside either in beds or in pots from October to December before first frosts. A bulb is essentially a collection of modified leaves which contains all the food that is necessary for growth – which is why hyacinth bulbs for example can be grown just with their roots in water.

  • Cyclamen hederifolium are the easiest of cyclamens to grow and are frost hardy. Cyclamen corms can be planted in autumn or spring. A corm is an adaptation of a stem. The corms should be planted when in growth and the tops of the corms should be level with the soil or only just submerged. Cyclamens do best in shade as they are essentially a woodland plant.

Friday 12th September 2014

Welcome to the first Friday gardening group blog of our new gardening year.  It was good to see the garden again, catch up with returning group members and  welcome new ones and get going with our gardening discussion and activities for 2014/15.

We discussed planned projects in the garden for the year ahead which will include replacing the old shed and landscaping the area around the shed and making a woodland garden around the cherry tree in the top garden. There is also a plan to prune back the large hawthorn hedge to try to improve the light and drainage in the big borders. A new development will be a ‘hot box’ for the greenhouse to help with propagating and Bridge will be giving advice on seed collecting and propagation techniques. There will be a number of open days throughout the year including plans to open for the National Garden Scheme, the Garden Gadabout and our own Friday Group charity event in July.

  • Tulbaghia ‘Hazel’ Tulbaghia is a South African genus and is commonly know as Society garlic. It is a bulbous or rhizomatous perennial with linear leaves and umbels of star shaped flowers. It can be planted in beds or pots and propagated by seed or division in spring. It is known to be snail proof. Tulbaghia ‘Hazel’ has pale brownish pink flowers and flowers from June to the first frosts. It can grow to a height of 60cm. The more common variety is Tulbaghia violacea which has pale purple flowers.
