Onoclea sensibilis - Sensitive fern

continental : Place the Onoclea sensibilis in a semishady place, with few hours a day of direct sunlight.
Normally these are very rustic plants, therefore can be grown in the garden all year long.

alpine : These plants do not like to be exposed to direct sunlight for long periods.
The Onoclea sensibilis are rustic plants, they can tolerate without any problem also intense frosts; during particularly rigid winters cover the aerial part with frost cloth.

mediterranean : These plants prefer semishady locations, but can be exposed for few hours to direct sunlight without any problem, above all during the coldest periods of the year.
They are very rustic plants, that do not suffer from cold.

Fertilization Onoclea sensibilis : At the end of winter bury an organic fertilizer at the base of the plant, or a slow-release granular fertilizer, we can intervene again at the end of summer. Acidophil plants may need 2-3 supplies of greening fertilizer during the year, every 3-4 months.

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 Onoclea sensibilis : When spring starts we can apply a sulphur fungicide treatment; the other treatments will be applied only in case the parasites are on the plants. Avoid the use of any treatments on the plants during bloom, which can injure the bees.
