Athyrium niponicum

continental : Place The Athyrium niponicum in a shady location, away from direct sunlight.
They can tolerate short slight frosts; in case of intense frost cover the aerial part with frost cloth.

alpine : We suggest to grow this plant in a shady location all year long.
We suggest to cover the plants with frost cloth in autumn even though they can tolerate slight frosts; place them in the greenhouse if possible.

mediterranean : Avoid to expose The Athyrium niponicum to direct sunlight, which can cause leaves sunburns.
The Athyrium niponicum can generally tolerate slight frosts without any problem, therefore they can be grown in the garden without any problem.

Fertilization Athyrium niponicum : 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 : Remember to water The Athyrium niponicum only when the soil is dry. During waterings try to dampen deeply the substrate, avoiding to drench it excessively.

alpine : The Athyrium niponicum prefer fresh but not soaked soils, therefore water only when the soil has been dry for few days; providing more frequent waterings in summer and avoid to give water in winter or during the coldest periods of the year.

mediterranean : The Athyrium niponicum needs very regular and generous waterings; give a good amount of water every week from March to October, but remember to allow the soil to dry out between two waterings. During very cold months or particularly rainy periods we can avoid watering.

Treatments Athyrium niponicum : 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.
