When to prune an apple tree
Are you curious about the content of green plant flower planting, such as when apple trees bloom? It will definitely bring you help. Let's learn about it together!
Apples are deciduous trees that can grow up to 15 meters tall, but cultivated trees are generally only 3-5 meters tall. It usually takes 2-3 years after planting for apple trees to start bearing fruit. So, when do apple trees bloom?
1. When do apple trees bloom
The blooming period of apple trees depends on the local climate, but it generally集中s in April to May. In some low-temperature areas, it may be postponed to early May to June. Apples are cross-pollinated plants, and most varieties cannot bear fruit with self-pollination.
2. When to prune an apple tree
Shaping and pruning of fruit trees is a time-sensitive task in the comprehensive management of fruit trees. When is the most suitable time for pruning is a topic of discussion among fruit farmers. According to the phenology of trees in winter, it can be said that pruning can be done from after the leaves fall off to before the next year's germination, but the best period is from December to the following January.
Too early or too late is not suitable. If it's too early, the sap is still flowing vigorously, and the cut ends can easily dry out; if it's too late, the backflow starts, and the tree loses water. From December to January, the water content of the tree is low, and the fruit tree completely enters the dormant period, with enhanced resistance to wind and dryness. This is the most suitable time for pruning, reshaping, and removing large branches.
Adjust according to the tree's condition, pruning weak trees first and then strong ones. Weak and old trees should be pruned early and first because the tree first allows nutrients to heal the wounds and then grows branches. Early pruning ensures that the wounds are almost healed by the time of germination, with balanced nutrient supply, ensuring normal growth. Pruning weak and old trees first also greatly increases their resistance to drought and severe cold, reducing frost damage and helping them survive the winter safely.
For strong and young trees, pruning should be delayed, allowing them to concentrate nutrients on healing wounds after germination before sending nutrients to the flower buds, without extra nutrients to promote branching and shooting. This is also the law of the tree's nutrient distribution.
The main purpose of winter shaping and pruning is to create a reasonable tree structure, ease the contradictions between the distribution of nutrients within the tree, regulate the relationship between nutrient growth and reproductive growth, and ensure a stable future tree vigor, good fruiting, and high yield.
