Actinidia

By John Hicks

Some climbers like ivy need no support other than that provided by their aerial roots whereas others, as for example the climbing roses, need tying in with string, plastic ribbon, webbing or a similar artificial aid.

Tradition has it that clematis produce their best efforts when the roots are shaded but the flowers are allowed to reach up into the sun. However, I believe a well-drained soil to be more important, otherwise losses in winter are liable to be heavy. A mulch of peat mixed with a handful of bone- meal is all the feed necessary.

Before attempting any planting examine the soil at the foot of an average house wall. Usually it consists of builders' leavings, sub-soil, pot crocks and other aridities, possibly enriched by a few tea leaves. All this must be excavated and replaced with soil from a fertile part of the garden.

A good mixture consists of 5 parts of garden soil to 2 parts of peat plus a 6-in. pot of bonemeal to every barrowload of the mixture. Only a narrow border need be made, 2 ft. wide by 15 in. deep, for given a good start healthy roots will penetrate less profitable fields.

I avoid hard pruning for the stems being hollow tend to die back along the whole branch. A thinning of the twigs is a permitted indulgence. A warm south or west-facing wall suits actinidia best.

Although ceanothus can be grown as a bush in the open garden, it is only happy in the colder gardens when given wall protection. However, it is worth all the devotion lavished on it. I remember a very old house in Hurworth, County Durham, which supported an enormous specimen of the variety A. T. Johnson. The brick mellowed by age to a warm buff pink made an ideal background to the blue flowers. See main list for full description. - 16887
