Polypodium cambricum problems — and how to fix them
Polypodium cambricum (Polypodium 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
As a lime-lover it sulks and rots in heavy, wet, acidic ground. Plant in gritty alkaline soil or a wall crevice with sharp drainage.
Summer die-back mistaken for death
Fronds naturally brown and disappear in summer dormancy. Don't dig it up; new fronds flush in late summer to autumn.
Deep shade with stagnant air
Very dark, still corners can encourage moss to smother small plants. Give it open, airy shade on rock or wall.
Slow establishment
Newly divided rhizomes can be slow to root. Keep them in contact with moist substrate and be patient through the first season.
