Troubleshooting
Blechnum chilense problems — and how to fix them
Blechnum chilense (Blechnum chilense) 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.
Frond scorch in dry sun
Combined sun and dry soil bleaches and crisps the fronds. Provide shade and keep the soil moist.
Cold damage
Foliage can be damaged in hard frosts at the colder end of its range. Mulch the crown and shelter it; cut back damaged fronds in spring.
Vigorous spreading
Creeping rhizomes can colonise widely in ideal conditions. Plant where spread is welcome or contain the roots.
Drying out
Browning and wilting follow if the rootball dries. Maintain steady moisture, especially in warm weather.
