The plant prefers light (sandy) and medium (loamy) soils and requires well-drained soil.The plant prefers basic (alkaline) soils. and can grow in very alkaline soils.It can grow in semi-shade (light woodland).It requires moist soil.
Requires a well-drained position and lots of old mortar rubble in the soil. Requires a humid atmosphere and some shade. A good plant for growing on a shady part of an old dry-stone or brick wall, also succeeding in full sun. A very ornamental fern, it is very tough but slow to establish.

Spores – best sown as soon as they are ripe on the surface of a humus-rich sterilized soil. Keep the compost moist, preferably by putting a plastic bag over the pot. Germinates in spring. Spring sown spores germinate in 1 – 3 months at 15°c. Pot on small clumps of plantlets into individual pots as soon as they are large enough to handle and grow them on in light shade in a cold frame or greenhouse. Keep the plants humid until they are well established. Once the plants are 15cm or more tall, plant them out into their permanent positions in the spring. Division in spring.
The fronds are astringent, deobstruent, emmenagogue, expectorant and ophthalmic. A distilled water made from the fronds has proved of benefit in the treatment of many eye complaints. The plant is also considered to be useful in the treatment of coughs and ruptures in children. It was at one time used as a herbal remedy for rickets and its tannin content renders it suitable for stopping bleeding from small wounds. The fronds are harvested in late spring and dried for later use
