Berberis thunbergii - Barberry

Fertilization Berberis thunbergii : 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 needs to be exposed to direct sunrays.
The Berberis thunbergii is a rustic plant, which doesn’t tolerate the winter cold, even when the nocturnal temperatures are very low.

alpine : Let's locate the The Berberis thunbergii in a very luminous place, preferably sunny.
The Berberis thunbergii can stand the cold, therefore it can be grown outdoors year round.

mediterranean : These plants favour sunny exposures, where they can enjoy, even for the whole day, some direct solar rays.
Grow the The Berberis thunbergii in the garden, in full ground; it can stand the cold.

continental : Let’s water every 1-2 weeks with 1-2 buckets of water, or even more often if the weather is hot and dry; we should always try to keep the ground slightly damp.

alpine : Water regularly, every 2-3 weeks, wetting the soil thoroughly by using 0-1 buckets of water and keeping it always a bit moist, although avoiding to soak it too much.

mediterranean : For a balanced development these plants need constant and abundant dampness; during this time of year it is good to water frequently, about 2-3 buckets of water at least every 0-1 weeks.

Treatments Berberis thunbergii : 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.
