Troubleshooting
Weigela 'Bristol Ruby' problems — and how to fix them
Weigela 'Bristol Ruby' (Weigela florida 'Bristol Ruby') 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.
Pruning at the wrong time
It flowers on the previous year's wood, so hard pruning in late winter removes the bloom. Prune the oldest stems right after the main spring flush instead.
Legginess and sparse bloom
Too much shade or neglected old wood makes plants open and flower poorly. Grow in full sun and renew a third of the oldest stems each year.
Aphids on new growth
Clusters on soft shoot tips cause distortion and sticky honeydew. Rinse off or treat with insecticidal soap; tolerate light infestations for beneficial insects.
Frost damage to early shoots
Late frosts can blacken tender new growth and reduce the spring display. Site out of frost pockets; the shrub recovers and may rebloom in summer.
