About this plant
This fern has lovely, slender, dark-green fronds, prominent, arching and very architectural. It is evergreen and is well suited to being cut, though this plays havoc with its elegant appearance. In North America it is used for Christmas decorations, which sounds positively barbaric.

Spring
Spring-Autumn · Outdoors
Water during dry periods
For plants in the ground, when there has been little or no rain for a period of 7-10 days and the soil is dry, give it a deep watering and repeat weekly until there is a downpour of rain. Check plants in pots more frequently, especially in hot weather.
Spring - early · Planting
Prune to the ground
Cut foliage to the ground before new growth starts.
Where stems are grown for their ornamental value, old stems should be removed either before new growth starts in spring, or during winter when they begin to look ragged or untidy.
Winter
Winter · Planting
Apply a protective mulch
Protect with a mulch so that the plant does not become too wet in winter.
A mulch is a covering that can: protect the soil surface from rain, heat and cold; deter weeds; provide nutrients. Organic indicates that material has vegetative origin e.g. manure, compost. Synthetics i.e. plastics, or stones are often called mulches.
