Troubleshooting
Gunnera manicata problems — and how to fix them
Gunnera manicata (Gunnera manicata) 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.
Winter cold damage
The crown is frost-tender. In cold-winter areas fold the dying leaves over the crown or mulch heavily to insulate it; unprotected crowns can be killed in hard frosts.
Drought collapse
If the soil dries, the enormous leaves wilt and brown rapidly. Permanent moisture at the roots is essential; site it where water is guaranteed.
Wind scorch and tearing
Exposed leaves are shredded and browned by wind and harsh sun. Plant in a sheltered position to keep the foliage whole and handsome.
Prickly handling and overcrowding
Leaf stalks bear sharp prickles, so wear gloves when working around it; its sheer size can also overwhelm smaller plantings, so allow ample space from the start.
