Polypodium cambricum 'Cambricum' problems — and how to fix them
Polypodium cambricum 'Cambricum' (Polypodium cambricum 'Cambricum') 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.
Acidic or waterlogged soil
Like the species it needs lime and sharp drainage; it rots in heavy, wet, acidic conditions. Use gritty alkaline soil or a wall crevice.
Reversion or weak fronds
Stressed or poorly fed plants may throw plainer fronds. Keep conditions cool and stable and divide regularly to maintain vigour.
Summer dormancy confusion
Natural summer die-back can look like death. Leave the rhizome in place; fresh lacy fronds emerge from late summer.
Sun scorch on fine fronds
The lacy fronds are more scorch-prone than the species. Keep it out of direct midday sun.
