To cultivate peach trees, it is first necessary to understand their requirements for environmental conditions. 1. Temperature: Peaches prefer a cool and mild temperate climate, with an average growing season temperature of 13°C to 18°C for pot cultivation. Peaches have a certain degree of cold resistance, with most varieties able to withstand low temperatures of -25°C to -22°C. Peaches require a certain amount of low temperature in winter to pass through dormancy normally, ensuring normal budding, flowering, and fruiting. Generally, the number of hours below 7.2°C is calculated, requiring 600 to 1200 hours. In southern China, due to the inability to meet the low-temperature requirements, phenomena such as the inability of flower buds to swell or the upper flower buds opening while the lower flower buds remain dormant, leading to the inability to bear fruit normally, can occur.
2. Light: Peaches prefer sunlight. Insufficient light can lead to poor root development, excessive growth of branches and leaves, few and poor-quality flower buds, severe flower and fruit drop, and poor fruit coloring, thus reducing the ornamental value of potted peach trees.
3. Soil: Potted peaches prefer well-drained, organic-rich, fertile slightly acidic to slightly alkaline potting soil, with a pH below 4.5 and above 7.5 being unsuitable for growth. In alkaline potting soil, yellow leaf disease is prone to occur. Additionally, peaches have poor flood resistance, so potting soil should not be waterlogged for extended periods, as root hypoxia can lead to yellow leaves and even plant death.
Most peach varieties are self-pollinating and can bear fruit, but some require pollinating peach trees or artificial pollination to bear fruit. Flowering consumes a large amount of nutrients, and the more flowers there are, the more nutrients are consumed. In potted peach trees, it is common to see a large number of flowers retained, which, after flowering, leads to a severe deficiency of nutrients in the tree, resulting in weakened growth of the branches and leaves, yellowing leaves, and thus causing massive flower and fruit drop, or even no fruit at all. Therefore, it is necessary to supplement fertilizers before and after flowering to replenish the nutrients consumed by flowering.
To ensure flowering and fruiting in potted peaches, I suggest you start from the following two aspects.
One, summer pruning. The main purpose of summer pruning is to convert branches into good fruiting branches and form a sufficient amount of high-quality flower buds. The main targets of summer pruning are young trees that have not yet produced fruit or have produced little fruit. 1. Remove suckers: In early spring, when branches grow to 3cm to 5cm, remove suckers from latent buds, upright branches on the back, and double buds on the nodes (retaining one). 2. Pinching: Frequent pinching is required for vigorous growth, while fewer pinches can be done for weaker growth, usually 2 to 4 times a year. The main targets for pinching are strong upright branches with obvious apical dominance, which can be pinched in the middle and lower parts where there are lateral buds to facilitate flower bud formation, with the lower the cutting position, the better. After mid-to-late August, all tender tips (apices) that have not stopped growing in potted peaches should be removed to fill the branches and improve flower bud quality. For young trees, the main branches can be pinched to fully utilize secondary branches to accelerate shaping. In May, when the branch tips grow to 40cm, select a suitable direction and healthy secondary branches in the middle and upper part of the branch for pinching, and usually no further pinching is done to prevent the growth of underdeveloped tertiary branches. 3. Branch pulling: The targets are usually smaller-angled, vigorous multi-year branches and new shoots that have produced a large number of lateral buds, with better results in July to August. 4. Thinning branches: During the pinching process, individual vigorous branches that are difficult to control can be thinned, and by mid-August, according to the density of the branches, strong upright branches (with more than 3 to 4 lateral branches) can be thinned appropriately, but care should be taken not to thin too much, as this may affect the growth of the potted peach. 5. Girdling and root pruning: For some vigorous potted peaches, root pruning can be done in mid-to-late July, cutting off or removing part of the root system, with the pruning amount controlled at about 15%.
Girdling of the trunk (without stripping) can also be performed, which can significantly inhibit the vigorous growth of the tree and promote flower bud formation.

Two, flower promotion methods. 1. Water control: Starting in mid-to-late July, reduce the amount of watering until the leaves show mild wilting, and continue this for about a month. 2. Pruning: In addition to trunk girdling, the method of twisting branches can also be used to inhibit the elongation of branches, accumulate photosynthetic products, and promote flower bud differentiation. 3. Strengthen comprehensive management: In satisfying the environmental requirements of potted peaches, it is necessary to strengthen fertilization and water management, as well as pest and disease control, to prepare a material foundation for flower bud differentiation. For example, for potted peaches that have not yet borne fruit or have borne little fruit, and with vigorous new shoot growth, the application of inorganic nitrogen fertilizer should be reduced and avoided throughout the year, and phosphorus and potassium fertilizers should be increased. For trees with a large number of flowers and fruits, 1 to 2 applications of 0.2% to 0.3% inorganic nitrogen fertilizer should be applied before and after flowering to make up for the nutrient deficit caused by flowering, while promoting new shoot growth, increasing leaf area, manufacturing and accumulating nutrients, preparing a material foundation for flower bud differentiation, and promoting the formation of flower buds.
