When is the best time for winter pruning of peach trees? The latest answer is here
Peaches are a relatively popular fruit. Peach trees are planted in all parts of our country, and when planting peach trees, the various management tasks are naturally indispensable. Among them, pruning is especially important, and pruning is divided into spring pruning, summer pruning, winter pruning and pruning in other seasons. Now that winter has arrived, when is the best time to carry out winter pruning of peach trees? Below, the editor will give everyone a brief introduction. Let's take a look!
1. Winter pruning time
When carrying out winter pruning on peach trees, it should be done within the period from December to February. The pruning time is very important and must not be too early or too late. Pruning too early or too late will cause the peach tree to consume a large amount of nutrients. This will have a great impact on the tree vigor, thereby affecting the peach tree's flowering and fruiting the following year. Moreover, when pruning, we should also pay attention to the planting variety, which is generally divided into southern varieties and northern varieties. Among them, southern varieties should undergo winter pruning in December. If it is a northern variety, then it must not be done in January when the temperature is at its lowest; it is best to carry out winter pruning in early to mid-February.
2. Winter pruning methods
Besides the main pruning time, the winter pruning methods for peach trees also cannot be ignored. This is because peach tree flower buds are pure flower buds and have the characteristic of being lateral. Therefore, when we carry out winter pruning on peach trees, we should mainly use heading back, supplemented by thinning and renewal pruning. During winter pruning, retain the flower-bud-like short fruit branches produced by the peach tree in the current year, and all other branches should be headed back. Also, the flower-bud-like short fruit branches should be thinned or left unpruned, while upright-growing competitive branches such as scaffold branches and extension branches should also be thinned. At the same time, if there are fruiting branch groups that have grown too long or too dense, then they should be properly renewal-pruned.
3. Degree of winter pruning
Then we should also pay attention to controlling the degree of winter pruning. First, we should prune according to the actual conditions of the planting area. For example, if the annual precipitation is not much, then the growth amount of peach tree branches will not be very large either, so heavy heading back should be carried out to promote fruiting shoots. Then pruning should be carried out according to the growth characteristics of the planted variety. For example, southern varieties of peach trees grow relatively moderately, so when heading back, it should be appropriately heavier. And some medium and long fruit branches should be retained. On the contrary, because northern varieties grow relatively vigorously, they should be lightly headed back, and the fruiting branches should mainly be medium and short fruit branches and flower-bud-like short fruit branches.
Finally, we should also prune according to the type of branch. When pruning extension branches, the pruning should be kept to a degree that produces many branches and does not leave the base bare. When pruning water sprouts, apart from retaining some outer branches and branch groups in bare areas of the inner canopy for fruiting, all water sprouts should be thinned from the base. For another example, when pruning overgrown fruiting branches, the principle should be heavy heading back, allowing them to bear about 4 fruits, and then grow multiple long, medium and short fruit branches, cultivating them into fruiting branch groups.
The above is a brief introduction to when is the best time for winter pruning of peach trees. That is all for today's introduction. This article is for reference only, and we hope it can be of some help to everyone!
