Athyrium niponicum

Fertilization Athyrium niponicum : 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 : Plant which favours shady locations, avoid exposing it to direct solar rays.
In autumn these plants are grown in the garden; they can tolerate temperatures a few degrees below zero without problems.

alpine : Let's choose a partially shaded place, protected by direct solar rays.
Autumn temperatures are easily tolerated by the The Athyrium niponicum which usually doesn’t get damaged by short freezing; if the temperatures should go below -5°C, let’s protect our plant with a non-woven fabric.

mediterranean : Avoid as much as possible that the plant be exposed to direct solar rays; therefore let's choose a shady location.
The Athyrium niponicum can stand temperatures a few degrees under zero, therefore they can be usually cultivated as garden plants.

continental : We suggest quite frequent and regular watering, in the matter of 1-2 buckets of water, but without exceeding; we should always remember to wait for the soil to dry completely between one watering and another; usually we should water every 2-3 weeks.

alpine : In this period of the year we must water only when the soil is perfectly dry, using 0-1 buckets of water; usually watering every 3-4 weeks can be enough.

mediterranean : During the autumn months these plants don’t need too much watering; we should remember anyhow to act regularly with 2-3 buckets of water, when the soil is clearly dry. Typically watering is done every 1-2 weeks.

Treatments Athyrium niponicum : 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.
