Growing Wisteria


 
 From Country Life:

How I love wisteria! It graced the front wall of our modest three-up, three-down terrace house when we got married and I trained it proudly so that, in the six years we lived there, its territory was extended year on year. It was the common Chinese wisteria (W. sinensis), generally the only kind that existed in our gardens for many years. Today, there are countless cultivars, mainly of Japanese origin, with strange names and, in some cases, strange colours and flower formations.

If you’re planting a new one, first check that you like the colour and flower form and buy a grafted plant, as it will bloom more reliably and at a much younger age. The graft union will be clearly visible a few inches above soil level. Plants that aren’t grafted and have been propagated by layering or cuttings can be irritatingly flower shy; there are ways to encourage blooming in older reluctant plants.

Wisteria needs a sunny wall. Don’t waste your time giving it a wall facing north or east. South and west are the more favoured aspects, where the wood will ripen most effectively. Then there’s the twice-yearly pruning. In July, tie in all questing growths that are needed to extend the plant’s coverage, but shorten all others to about 1ft. In January, cut back all sideshoots to finger length. Do this every year and your plant should not disappoint. (Read more.)
