Heuchera 'Hollywood' problems — and how to fix them
Heuchera 'Hollywood' (Heuchera 'Hollywood') 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.
Crown rot
Persistent wetness around the crown leads to rotting; plant in well-drained soil and avoid mulching directly against the stem.
Vine weevil larvae
Root damage causes sudden collapse of the plant; apply beneficial nematodes to the soil in late summer as a preventive treatment.
Rust
Orange pustules on leaf undersides in cool, damp conditions; remove affected leaves and treat with a copper-based fungicide if severe.
Leaf scorch
Brown leaf edges develop in intense afternoon sun or during drought; relocate to a shadier spot and ensure consistent watering.
Slugs and snails
Young foliage is attractive to molluscs; use copper tape, grit barriers, or wildlife-safe slug pellets around new spring growth.
