What are the latest precautions for autumn pruning of cherry trees?
Cherries have a very large market demand in our country, are welcomed by many people, and have a relatively wide planting area. When growing cherry trees, we need to do a good job of pruning according to seasonal changes. Especially in autumn, autumn pruning work has a very large impact on the growth of cherry trees the following year, and there are also many points that require our attention. So what precautions are there for autumn pruning of cherry trees? Let's take a look below!
1. Smooth cut
When pruning cherry trees, we must be sure to keep the branch cuts smooth enough. Generally, a surface of about 45 degrees should be kept with the bud at the cut. Cutting should start downward from the opposite side of the bud, and at the same time the slanted surface of the cut should be kept level with the tip of the bud at the cut. In this way, the wounded surface can be reduced as much as possible, the healing speed can be improved, and the growth speed after the bud sprouts can be maintained. Finally, for the cuts left by thinning branches, they should be removed at the branch point, and no stubs should remain.
2. Sectional work
When pruning cherry trees in autumn, we should adjust the pruning method according to the tree shape and tree age of the cherry tree. For example, when pruning branches and trunks, we should mainly use the sectional work method. First, we should saw a cut at a position about 20 cm above the saw cut. From the lower end of the branch upward, make a cut with a depth kept at about half of the branch. Then saw off the branch from the upper end, keep the stub, and finally remove the stub from the previous saw cut. In this way, splitting of the branches and trunk can be effectively prevented.
3. Flat saw cut
When pruning, in addition to keeping a smooth cut, we should also pay attention to making the saw cut flat enough. Because after pruning, it is inevitable to encounter adverse weather such as rainy days. If the saw cut is not flat enough, then after being exposed to rain it is prone to rot, and it is also prone to infection by pathogens, causing various diseases and pests. So after sawing a cherry tree, we should promptly use copper sulfate solution and so on to disinfect the saw cut. Then apply an appropriate amount of protective agents such as protective wax to the saw cut. This can not only avoid rot and drying of the saw cut, but also improve the healing speed of the saw cut.
4. Pruning time
The autumn pruning time for cherry trees also requires our attention. Generally, autumn pruning of cherry trees should be carried out after September. Because at this time the new shoots on the cherry tree have basically stopped extending, and growth is in a semi-stopped state. The cherry tree will not react too strongly to pruning, but there will still be some tender green parts growing at the tips of the new shoots, consuming excessive nutrients. Therefore, we should pay attention to cutting them off in time to save nutrients. However, because every fruit grower has their own management habits, and the conditions of every orchard are somewhat different, whether to prune and the pruning time should still be determined according to the actual situation.
The above is a brief introduction to the precautions for autumn pruning of cherry trees. That is all for today's introduction. This article is for reference only, and we hope it can help everyone!
