Troubleshooting
Weigela 'Florida Purpurea' problems — and how to fix them
Weigela 'Florida Purpurea' (Weigela florida 'Purpurea') 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.
Faded leaf colour in shade
Insufficient light reduces the distinctive purple-bronze foliage to ordinary green; move to a sunnier position.
Leggy, overcrowded growth
Prune out one-third of the oldest stems at the base immediately after the main spring flowering to keep the plant compact and well-branched.
Honey fungus (Armillaria)
On susceptible soils, honey fungus can attack the roots; ensure good drainage and remove affected plants and root material promptly.
Capsid bug damage
Distorted, pin-holed young leaves in spring are caused by capsid bugs; damage is cosmetic and rarely requires treatment.
Winter dieback of tips
In very cold winters, stem tips may be killed back; prune back to healthy wood in spring — the shrub recovers vigorously.
