Aralia spinosa

continental : They prefer locations where they can receive direct sunlight for at least few hours.
They can tolerate short slight frosts; in case of intense frost cover the aerial part with frost cloth.

alpine : It is advisable to place these plants in a very bright location, exposed to direct sunlight.
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 : Place these plants in a very bright location, possibly exposed to direct sunlight.
The Aralia spinosa can generally tolerate slight frosts without any problem, therefore they can be grown in the garden without any problem.

Fertilization Aralia spinosa : Houseplants are exposed all year long to a climate favourable for their growth, therefore they do not have an actual rest period, even though the poor insolation in autumn and winter slow their growth. Try to give a liquid fertilizer all year long, dissolved in normal waterings. Increasing the supply of fertilizer in spring, decreasing it during the rest of the year. It is possible to mix with the topsoil in the pot some slow-release granular fertilizer, in two supplies, one at the end of winter and the other one at the end of summer.

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 Aralia spinosa 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 Aralia spinosa 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 Aralia spinosa : 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.
