Trillium grandiflorum - White trillium

Fertilization Trillium grandiflorum : We should enrich the soil of newly planted bulbous plants with organic fertilizer; it’s not necessary to fertilize summer flowering bulbous plants during this period of the year.

continental : Plant which favours shady locations, avoid exposing it to direct solar rays.
The Trillium grandiflorum is a rustic plant, which doesn’t tolerate the winter cold, even when the nocturnal temperatures are very low.

alpine : Let's choose a partially shaded place, protected by direct solar rays.
The Trillium grandiflorum can stand the cold, therefore it can be grown outdoors year round.

mediterranean : Avoid as much as possible that the plant be exposed to direct solar rays; therefore let's choose a shady location.
Grow the The Trillium grandiflorum 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 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 1-2 weeks.

alpine : In this period of the year we must water only when the soil is perfectly dry, using 0-1 glasses of water; usually watering every 2-3 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 glasses of water, when the soil is clearly dry. Typically watering is done every 0-1 weeks.

Treatments Trillium 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.
