No matter which kind of plant is pruned, autumn is the most suitable, especially geranium, which almost enters the semi dormancy period in summer and stops growing. Autumn pruning can promote germination of new buds, and cut off the thin, yellow, infected with diseases and insect pests, as well as the inward growing branches. When pruning, keep the height of the branches consistent.
When pruning geranium, it is necessary to select it above the stem and leaf, preferably close to the base, otherwise it is easy to cause half cut branches, sometimes even if pruned above the stem and leaf, there will be pit necrosis. If there is yellowing under the cut after trimming, it is necessary to remove the yellowing part in time and apply healing agent on the wound, otherwise, it will lead to black necrosis of the wound.
