Arisaema griffithii - Jack in the pulpit

continental : Place the Arisaema griffithii in a semishady place, with few hours a day of direct sunlight.
These plants do not tolerate temperatures below zero, therefore in winter they are grown in the apartment or in the hothouse.

alpine : These plants do not like to be exposed to direct sunlight for long periods.
These plants do not tolerate frosts, not even slight ones; it is advisable to grow them in a sheltered place or in the greenhouse.

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.
We suggest to avoid to expose these plants to winter cold; we can place them in the greenhouse or in a sheltered location, or cover the aerial part with frost cloth.

Fertilization Arisaema griffithii : 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 griffithii 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 griffithii 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 griffithii : 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.
