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.

Plant identification:

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.

  • Aster blue star is more compact growing to max of 4′ with lovely lavender blue coloured flowers.

  • Aster Kylie is very sprawling with masses of semi double tiny pink flowers

  • Rudkeckia triloba is a very reliable self seeding biennial and gives a long display of flowers. It is very attractive to butterflies.

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.

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.

  • Fritillaria imperialis grow to 3′ and need full sun and is part of the Liliaceae family. Plant in autumn and they flower in April and May.

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.

  • Cobaea scandens  This climber is commonly known as the cup and saucer vine. It is a vigorous perennial climber which is usually grown as an annual as it is quite tender. It has fragrant bell shaped flowers which change from greenish- white to purple and show themselves from August until the first frosts. It comes from Mexico and needs a sheltered sunny wall or trellis. It is pollinated by bats.
