Troubleshooting
Tiramisu Heuchera problems — and how to fix them
Tiramisu Heuchera (Heuchera 'Tiramisu') 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
Caused by soggy soil or planting too deep. Ensure sharp drainage and keep the crown at or just above soil level.
Frost heave
Shallow woody crowns are pushed out of the ground over winter; re-firm plants in spring and mulch to insulate roots.
Vine weevil
Grubs chew roots, causing sudden wilting; check container plants and treat with nematodes if larvae are found.
Faded leaf colour
Too much shade mutes the amber and red tones; move to a brighter part-shade spot for stronger pigment.
