Symphytum grandiflorum

Fertilization Symphytum grandiflorum : During autumnal months let’s diminish the fertilizations to medicinal plants; if we’re treating perennial plants, as the cold temperatures arrive, we should add some organic fertilizer which will be used by the plants until spring arrives.

continental : plant which needs to be exposed to direct sunrays.
The Symphytum grandiflorum 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 Symphytum grandiflorum in a very luminous place, preferably sunny.
The Symphytum grandiflorum 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 Symphytum grandiflorum in the garden, in full ground; it can stand the cold.

continental : We suggest quite frequent and regular watering, in the matter of 2-3 glasses 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 1-2 glasses 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 3-4 glasses of water, when the soil is clearly dry. Typically watering is done every 1-2 weeks.

Treatments Symphytum grandiflorum : 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.
