Wisteria 'Amethyst Falls' problems — and how to fix them

Wisteria 'Amethyst Falls' (Wisteria frutescens 'Amethyst Falls') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.

All leaves, no flowers

Usually caused by too much nitrogen, too much shade or lack of summer pruning. Use a high-potassium feed, full sun, and prune in summer and winter.

Inadequate support

Even this compact wisteria is a strong twiner that can warp gutters and weak trellis; provide robust, dedicated supports from the start.

Missing the pruning window

Flowering depends on cutting back whippy shoots in summer and again in winter; neglecting this gives a tangled, shy-flowering plant.

Frost damage to early buds

A late frost can blacken emerging flower buds; a sheltered site protects the bloom in cold-spring areas.
