They are very rustic plants, that do not suffer from cold.

Fertilization Blechnum penna-marina : Houseplants are exposed all year long to a climate favourable for their growth, therefore they do not have an actual rest period, even though the poor insolation in autumn and winter slow their growth. Try to give a liquid fertilizer all year long, dissolved in normal waterings. Increasing the supply of fertilizer in spring, decreasing it during the rest of the year. It is possible to mix with the topsoil in the pot some slow-release granular fertilizer, in two supplies, one at the end of winter and the other one at the end of summer.

continental : These plants prefer dry soils, therefore avoid to water them too often; it can be necessary to intervene more often during summer, in very hot and dry periods.

alpine : We suggest occasional waterings; intervene occasionally from April to September, when the soil is completely dry. During the rest of the year avoid watering, or slightly dampen the soil only when it has been very dry for few days, in case the plant is starting to fade.

mediterranean : Waterings will be rather poor and less frequent, remember to increase waterings during the hottest periods of the year. The soil can remain dry also for few days before the plant needs new waterings.

Treatments Blechnum penna-marina : Normally we intervene in case parasites are on the plant; in any case a precautionary treatment against fungal diseases in spring can be useful, applying Bordeaux mixture on the buds before they grow too much.
