Wisteria floribunda 'Multijuga' problems — and how to fix them
Wisteria floribunda 'Multijuga' (Wisteria floribunda 'Multijuga') 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.
Racemes shorter than expected
Insufficient sun, dry roots during flowering or an immature plant — full sun, steady moisture and time produce the signature long trusses.
No flowers for several years
Plants on their own roots take many years to bloom; choose a grafted specimen and prune in summer and winter to build spurs.
Heavy trusses needing space to hang
Trained flat against a wall the long racemes get squashed — site over an arch, pergola or arbour so they dangle freely.
Frost damage to buds
Late spring frosts can brown the opening racemes; a sheltered, sunny wall reduces the risk.
