Chinese Astilbe 'Visions' problems — and how to fix them
Chinese Astilbe 'Visions' (Astilbe chinensis) 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 scorch
Brown, crispy leaf tips from too much direct sun or drought stress; relocate to a shadier spot and water more consistently.
Failure to flower
Often caused by deep shade or clumps too congested to bloom; divide every 3-4 years and ensure at least 2-3 hours of indirect light.
Crown congestion
Woody, congested crowns flower less freely; lift and divide in early spring, discarding the woody centre and replanting vigorous outer portions.
Powdery mildew
White coating on leaves in dry, sunny conditions; increase watering and mulch thickness to maintain soil moisture.
Vine weevil
Unexplained wilting in container-grown plants may indicate vine weevil larvae; treat with nematodes in late summer.
