Berberis gagnepainii var. lanceifolia - Darwin's berberis

Fertilization Berberis gagnepainii var. lanceifolia : 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 gagnepainii var. lanceifolia 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 gagnepainii var. lanceifolia in a very luminous place, preferably sunny.
The Berberis gagnepainii var. lanceifolia 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 gagnepainii var. lanceifolia in the garden, in full ground; it can stand the cold.

continental : We suggest quite frequent and regular watering, in the matter of 1-2 buckets of water, but without exceeding; we should always remember to wait for the soil to dry completely between one watering and another; usually we should water every 2-3 weeks.

alpine : In this period of the year we must water only when the soil is perfectly dry, using 0-1 buckets of water; usually watering every 3-4 weeks can be enough.

mediterranean : During the autumn months these plants don’t need too much watering; we should remember anyhow to act regularly with 2-3 buckets of water, when the soil is clearly dry. Typically watering is done every 1-2 weeks.

Treatments Berberis gagnepainii var. lanceifolia : 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.
