Propagation by cuttings is an easy and quick way to get new plants. However, the mother plant should be strong and healthy so as not to unnecessarily burden it. After a few weeks, the first roots usually form, then the cuttings can be individually moved into a planter and gradually poured more. When raising cuttings in autumn, they should be kept in a cool, but frost-free place. Keep the plant substrate much drier than cuttings in spring. At the beginning of spring, the young plants again brighter and warmer, after the last late frosts move outside.

Diseases & pests
With care mistakes, the geraniums become much more susceptible to diseases and pests. The causes of diseases often include permanently wet leaves. As a precautionary measure, always water the plants from below and not directly over the leaves. Extremely cool weather, a persistent lack of light and excessive fertilization also weaken the pelargonium's immune system. Pests can be combated with environmentally friendly home remedies, however, the treatment must be repeated often because they can be very persistent. If it has come to a particularly strong infestation, then the affected parts of plants are completely removed. Otherwise, the pests spread extremely fast and infest in the worst case, the neighboring plants.
