Explanation of pruning methods for persimmon trees (key points for reasonable pruning, retaining branches and management of persimmon trees)

1. Pruning young trees

Sapling persimmon trees usually refer to small persimmon trees that are still growing and developing and have not yet borne fruit.

Because this tree is young, its roots, stems and branches are relatively weak. Therefore, when pruning, the main focus is on cultivating the skeleton, stretching the branches and shaping the tree shape. At the same time, pinching is also used to promote the growth of fruiting branches.

1. Cultivate skeleton pruning

Regarding fruit tree pruning, there is a folk saying that "big branches pull apart the main frame, and the fruits are on the small branches."

The so-called "big branches" grow from young branches, so when the young tree is still small, the branches on the main trunk are the key parts to open the angle to form the backbone. When pruning, you must cut what should be cut and keep what should be kept according to the tree's vigor.

For those that remain, we need to open their angles and let them grow in a balanced manner in a direction that is conducive to light and ventilation.

After pruning young trees, the branches that remain on the trees will not only form the skeleton of the big tree in the future, but also serve as the backbone connecting the roots and fruiting branches, acting as a link for nutrient transport.

Therefore, in the next two or three years, before the trees bear fruit, they are still the focus of "cultivation", and efforts are made to make them grow in a sparse tree position that is conducive to light and ventilation.

2. Prune to create a chick shape

Winter pruning of young persimmon trees not only plays a role in cultivating the skeleton, but is also the key to supporting the tree shape in the future.

Therefore, during the growth stage of young trees, it is necessary to cut off excess side branches and overgrown branches during winter pruning so that the whole plant has a rough frame shape when viewed from a distance, and the tree appears balanced when viewed from close up, which is conducive to lighting and ventilation.

2. Pruning of mature fruit trees

When persimmons begin to bear fruit, they have reached adulthood. Pruning at this time is similar to pruning young trees. However, as the annual rings increase, the plants will grow taller and the branches will become more vigorous, and the workload of winter pruning will gradually increase each year.

1. Dwarfing pruning

Persimmon trees are large trees with deep roots. As they grow year after year, they inevitably become too tall, making them difficult to pick. Therefore, if they grow in places where it is inconvenient to pick them by machine, they should be dwarfed during winter pruning.

The pruning method is to first shorten the main trunk that is still growing, then shorten the excessively high skeleton branches, and finally apply protective material to the affected area.

2. Modeling and pruning

If the grown persimmon trees are not shaped when pruned, they often have branches and leaves that are long and uneven, which not only causes unnecessary nutrient waste, but also affects the beauty of the tree shape and the ventilation of the orchard.

Therefore, when pruning in winter, it is advisable to cut off branches that are too high or too long, or branches that affect the beauty of the tree shape, according to the tree's vigor.

3. Lighting and pruning

There is a folk saying that goes: "Small trees depend on the number of branches to produce fruit, while large trees depend on the light and ventilation to produce fruit." This means that small trees depend on the number of branches to produce fruit, while large trees depend on the light and ventilation to produce fruit.

Based on this, when we prune large persimmon trees with vigorous stems and branches, in addition to cutting off sick, weak and dry branches, we also need to cut off densely growing, crossing and overlapping branches to ensure that they receive even light and are well ventilated.

4. Disease prevention pruning

Winter pruning of persimmon trees is a "spring cleaning" to remove rotten and old leaves, eliminate weak and keep strong leaves, and prevent and cure diseases.

During every winter pruning, people first prune off the diseased and weak branches and dry branches that are host to pathogens and burn them.

In addition, the subsequent disinfection and sterilization process naturally plays a good role in preventing and curing diseases, making the persimmon trees less "troubled" by many diseases and growing well.
