Onoclea sensibilis - Sensitive fern

Fertilization Onoclea sensibilis : In autumn we must plant a good quantity of organic fertilizer of humus at the base of the shrubs . This type of fertilization, besides improving the mixture of the soil, makes macroelemnts, prevalently nitrogen, available for 3-4 months. In this manner the soil near our shrubs has a source of nitrogen which will be prolonged until the next spring.

continental : We can grow the the Onoclea sensibilis in a place where it can receive a few hours a day of direct sunlight, but where it is protected from the sun during most of the day.
The Onoclea sensibilis is a rustic plant, which doesn’t tolerate the winter cold, even when the nocturnal temperatures are very low.

alpine : Locate this plant in a partially shaded place, where it can receive a few hous of direct solar light.
The Onoclea sensibilis can stand the cold, therefore it can be grown outdoors year round.

mediterranean : We suggest a pretty sheltered location, so that the plant can receive direct solar rays only during the coolest hours of the day.
Grow the The Onoclea sensibilis in the garden, in full ground; it can stand the cold.

continental : We advise leaving the ground prevalently dry, watering from time to time, every 2-3 weeks; if there are intense rains and the weather is quite cold we can reduce the watering even more. Usually 1-2 buckets of water are used.

alpine : We suggest watering rarely, such as every 3-4 weeks with 0-1 buckets of water, but only when the weather is mild, and the substratum has been dry for days.

mediterranean : During this time of year we suggest watering only once in a while using 2-3 buckets of water, leaving the soil dry for a few days before watering it again. If the weather is cold irrigate rarely. Between one watering and the other 1-2 weeks should go by.

Treatments Onoclea sensibilis : During the cold months many pathogens spend the winter in the ground, at the feet of our plants; let’s treat the plants struck by black spot disease or by leaf curl disease with particular attention by applying a wide-range anticryptogamic treatment, to vaporize even on the ground. Let’s gather and destroy the leaves of the sick plants.
