■ Plant wisterias while they are dormant, from about now until February, as soft growing shoots are easily damaged.
■ Plant in good, well-drained soil in a sunny place; once they are established, wisterias are unexpectedly drought tolerant.
■ Dig a large, deep hole – this should be at least twice the size of the root ball – and fork in plenty of well-rotted compost.
■ Keep young plants well watered.
■ Feed in spring with fish, blood and bone. Or use a rose or flowering shrub fertiliser.
