Imperial Geranium

Imperial Geraniums

The imperial geranium also known as Pelargonium grandiflorum is native to southern Africa. It is a herbaceous plant characterized by not too large stems and lobed green leaves with notched sides. Flowering takes place in a specific time frame: from May to August. The inflorescences are very particular compared to the other species of flowers, in fact, it is precisely for this reason that it has this name. Their colors range from lilac, pink, white, to red and the central part of each flower starts with an increasingly darker coloration and then gradually clears; some also have veins. During the planting of this variety, care must be taken to choose an area that is not exposed to the wind and, in winter, which is not subject to severe frost.

The pruning of the imperial geranium mainly follows two phases: the first is given by the elimination of the now dry inflorescences, in such a way as to favor the birth of new and more luxuriant flowers, while the second phase is put in place when the plant is at rest and consists of a reduction pruning. Watering must take place according to precise rules with the aim of not having a soil that is too dry but not too wet. During the spring and summer season, it is necessary to irrigate the plant of this variety in order to have a damp soil. In winter and autumn watering must be significantly reduced and it is necessary to wait for the earth to dry. You have to be very careful, during this practice, not to wet the leaves and flowers to prevent the plant from being hit by Botritys.Imperial Geranium: Diseases and Pests

If preventive practices are not implemented, the imperial geranium can be attacked by innumerable pests and diseases. It can be subject to the aggression of aphids, red spider mites, cochineal and fungus attack. The presence of these parasites is visible to the naked eye, due to the presence of black and yellowish spots in the lower region of the leaves, cobwebs (in the case of red spider mites) and the presence of a sticky substance inside which the cochineal nestles. All these pests can be removed manually, if the region is reduced. The cochineal, for example, is removed using a cotton pad soaked in water and alcohol; it passes over the affected area and then the plant is washed. Alternatively, it is possible to spray fungicides or pesticides onto the plant.
