Troubleshooting
Heuchera 'Peach Flambe' problems — and how to fix them
Heuchera 'Peach Flambe' (Heuchera 'Peach Flambe') 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
Wet soil held against the crown rapidly leads to rot; ensure free-draining planting conditions and do not over-mulch around the stem.
Vine weevil larvae
Invisible root grubs cause abrupt plant collapse; preventive nematode application (Steinernema kraussei) in late summer is the most effective control.
Rust
Orange-brown spore patches on leaf undersides in humid, warm weather; remove affected leaves and apply a copper fungicide at first sign.
Leaf colour fading
The peach tones fade in full shade or intense summer heat; position where morning sun and afternoon shade can be reliably achieved.
Slugs and snails
Young spring foliage is especially vulnerable; use grit, copper tape, or wildlife-safe pellets around emerging growth.
