Basically, maples should be cut as little as possible, as these trees have a strong tendency to bleed and also quickly become infected with various pathogens. The red maple (Acer rubrum), native to North America, is no exception to this rule. However, as the very positive experiences of many bonsai lovers show, pruning is definitely possible and in many cases even makes sense under certain conditions and when observing various rules.
When and how do I properly cut a red maple?
Caution is advised when cutting the red maple (Acer rubrum): only cut when necessary and in a frost-free period before the leaves emerge. Use sharp, disinfected tools and avoid cutting old wood. Seal cuts with wound closure agent.
Do not cut more than absolutely necessary
When it comes to pruning, the red maple is quite sensitive, as it - like all maples - tends to bleed. In addition, pathogens quickly penetrate through the open wounds, which in turn leads to a weakening of the tree and the death of the affected parts of the plant, if not the entire tree. In addition, red maple, which is also typical of various types of maple, does not sprout from old wood. However, pruning may be necessary for various reasons, for example
- to remove dead shoots and branches
- cutting away diseased or fungal plant parts
- to stimulate bushier growth
- keeping a potted plant or bonsai small
- forcing the tree into a certain shape
Instructions for a successful pruning
Of course, necessary pruning does not always result in the tree dying, as long as you adhere to the following rules:
- Always prune in the right season.
- Only use disinfected and sharp tools.
- Seal cuts with a wound closure agent.
- Suitable wound closure products are available primarily from bonsai specialist shops,
- because they have a long experience with maples.
- Never cut into old wood
- or. only if it is absolutely necessary.
- Do not cut shoots and branches directly at their origin, but leave a small stub.
- This dries up over time.
- Always cut a few centimeters before a bud.
- From here the tree can sprout again.
The right time to prune
Due to their tendency to bleed, maples should never be cut during the growing season as sap pressure is very high at this time and bleeding cannot be stopped. Since pruning should not be done in late autumn or winter due to the risk of infection, it is best to use pruning shears in spring. To do this, choose a frost-free period before the leaves emerge.
Tip
Dead plant parts can be cut back at any time as long as he althy shoots and branches are not affected.
