Cultivation details

Very hardy and easily grown in light shade in any reasonable soil[187]. Prefers a sandy humus-rich soil in a shady position that is moist even in winter[1]. Tolerates part sun for up to 6 hours a day if the soil remains moist[200]. Prefers a pH in the range 6.5 to 7.5[200]. A very ornamental plant[1]. Members of this genus are rarely if ever troubled by browsing deer[233]. Remove old fronds from the plant in the spring because they may harbour fungal diseases[200]. Some named forms have been selected for their ornamental value[187].

Plant Propagation

Spores - best sown as soon as they are ripe, though they can also be sown in the spring. Sow them on the surface of a humus-rich sterilized soil. Keep the compost moist, preferably by putting a plastic bag over the pot. Pot on small clumps of plantlets as soon as they are large enough to handle and keep humid until they are well established. Do not plant outside until the ferns are at least 2 years old and then only in a very well sheltered position. Division. This is best done in the spring.
