Decoration and cutting is a very complex and important thing, but some people don't pay much attention to the trimming of geranium, often have some incorrect understanding, for example, some people think that they can't cut the geranium again when the shape is not good-looking, some people are reluctant to cut it, some people think it's neat and tidy without cutting. However, it should be noted that only when the cut is neat can it heal quickly, especially for the thick plant, it needs a neat incision. It is better to disinfect the cutting tools, once for each cutting. In order to prevent the necrosis of branches, the cut of pruning should be daubed with grass ash, ash or plant wound healing water. When the branches are stained with water, the nodes of the stems will turn black. The more close they are to the bottom, the more serious it is because of the mould. At this time should be more sun, or eventually will become rotten leaves.
1. Tools: the scalpel and razor can be trimmed and sharp tools should be selected as much as possible.
2. Time: autumn. Because it is easy to recover growth, plants have a certain self-protection system in summer, so after summer, plants are weaker. To promote its new branches and buds, it needs to be properly pruned.
3. Main points: the length of pruning is divided by observing the proportion of mother plants. When pruning, pay attention to the height and try to keep consistent. The branches that are too thin and long to the inside are cut off. The cutting position should also be on the top of the stem, as close as possible to the node of the stem, otherwise half of the stem will rot or necrosis, sometimes even on the node of the stem. In addition, if there is yellowing under the trim, it must be broken off, if not treated, there will also be necrosis.
