Dryopteris erythrosora

Spring - late · Outdoors

Feed with slow release fertiliser

Apply a general purpose slow release fertiliser, spreading it around the root area of the plant as it is coming into growth. (Or apply a liquid feed at regular intervals throughout the growing season.)

This is a simple way to provide a nutrient boost as a single annual procedure.

Spring-Autumn · Outdoors

Water during drought

In drought conditions where established plants in the ground have had no water for a month, do a deep watering. If drought continues repeat after a fortnight. Plants only need watering during spring to autumn growth. Check plants in pots more often.

Established plants have a good degree of drought tolerance. Water after a prolonged period of drought. Many drought tolerant plants can rapidly revive, even when much of the foliage has died. They will respond with new growth.

Winter-Spring · Planting

Prune damaged fern fronds

You can remove old fronds in winter if they look tattered. Carefully cut them off using secateurs. Other fronds can be removed as they break, die or fail in spring. Cut them off carefully so as not to damage the young, emergent growth.
