Heucherella 'Tapestry' problems — and how to fix them
Heucherella 'Tapestry' (Heucherella 'Tapestry') 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.
Frost heaving
The shallow crown can be pushed out of the ground over winter freeze-thaw cycles; firm plants back and mulch to protect the crown.
Vine weevil
Root-feeding grubs cause sudden wilting and collapse; notched leaf edges signal adults, treat soil with nematodes for the larvae.
Powdery mildew
White coating appears in dry, crowded, poorly ventilated spots; improve airflow and avoid wetting the foliage.
Crown rot
Wet, poorly drained winter soil rots the crown; plant high with sharp drainage to prevent collapse.
