Arisaema sikokianum - Jack in the pulpit

continental : Place the Arisaema sikokianum in a semishady place, with few hours a day of direct sunlight.
They can tolerate short slight frosts; in case of intense frost cover the aerial part with frost cloth.

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 : 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.
The Arisaema sikokianum can generally tolerate slight frosts without any problem, therefore they can be grown in the garden without any problem.

Fertilization Arisaema sikokianum : Bulbous plants are fertilized in spring and summer, using a specific fertilizer, to improve the storage of nutritional substances in the bulbs, in order to have a generous bloom the next year.

continental : It is advisable to water regularly, specially during the hottest months of the year, avoiding to leave the soil dry for very long periods; the Arisaema sikokianum like slightly humid substrates all year long. In autumn and winter you can avoid watering, or intervene during warmest days only.

alpine : Try to keep a mostly humid soil, remember to water generously specially in summer; we can avoid watering during the cold season, or decrease waterings, intervening only in case of long duration drought.

mediterranean : Water the Arisaema sikokianum rather regularly from March to October, always allowing the soil to dry out well between two waterings. Avoid water excesses or stagnating water; during the cold season waterings can be decreased or suspended.

Treatments Arisaema sikokianum : 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.
