Troubleshooting
Purple Bergenia problems — and how to fix them
Purple Bergenia (Bergenia purpurascens) 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.
Slug damage
Young growth and leaves are vulnerable to slug attack; apply controls in spring and autumn.
Vine weevil larvae
Root damage causes wilting; apply nematode-based biological controls in late summer.
Leaf scorch
In hot, dry summers leaves may scorch; improve moisture retention with mulching.
Frost damage to flowerheads
Spring flowers are vulnerable to late frosts; protect with fleece during cold snaps.
Congestion
Clumps lose vigour over years; lift and divide every 4-5 years in autumn.
