Pelargonium grandiflorum - Geranium

Fertilization Pelargonium grandiflorum : Annual plants tend to wither during the autumn period, usually we fertilize regularly up until the plants are flush, otherwise watering and fertilizing is interrupted.

continental : plant which needs to be exposed to direct sunrays.
During the autumn these plants can be left outdoors, but we suggest moving them to a place where they are sheltered from the frost as soon as the minimum temperatures go below zero.

alpine : Let's locate the The Pelargonium grandiflorum in a very luminous place, preferably sunny.
In this period of the year we suggest paying attention to sudden freezing, since the The Pelargonium grandiflorum can’t stand temperatures below zero; if the autumn climate is particularly harsh we suggest locating the plants in a sheltered place or in a cold greenhouse.

mediterranean : These plants favour sunny exposures, where they can enjoy, even for the whole day, some direct solar rays.
In this period of the year The Pelargonium grandiflorum can be cultivated outdoors; it can’t always stand quick dropping temperatures, therefore we suggest locating it in a sheltered spot. They can’t stand frost.

continental : Let’s water every 0-1 weeks with 3-4 glasses 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 1-2 weeks, wetting the soil thoroughly by using 2-3 glasses 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 4-5 glasses of water at least every 0-0 weeks.

Treatments Pelargonium 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.
