Weigela 'Midnight Wine' (Weigela florida 'Elvera') 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.
Leaf colour fading to green
Insufficient sunlight is the primary cause. Relocate to a position receiving at least 6 hours of direct sun to restore deep burgundy colouration.
Powdery mildew
Small plants in congested spots can be susceptible. Ensure good air circulation and avoid overhead watering.
