Flowering season to promote flowers
Apple tree flower buds originate from the transformation of leaf buds. In the first year, during summer and autumn, these buds undergo differentiation, and in the second year, they bloom and bear fruit. However, only when the trees are healthy, with full foliage and strong photosynthetic capacity, can high-quality flower buds be formed. This process takes approximately 150 to 180 days, laying a solid foundation for a bountiful harvest.
First, thinning flowers and fruits is essential to reduce excessive nutrient consumption and encourage better flower bud development. The key is to act early—during normal weather conditions, it's advisable to remove about 10–20% of the flowers to prevent frost damage. It’s better to thin flowers than to thin fruits, and even better to thin buds before flowering. The earlier the intervention, the higher the stored nutrients, allowing for more concentrated growth of flowers, fruits, and leaves.
Second, promoting early growth of branches and leaves is crucial. Fertilizer management plays a significant role in this process. For mature fruit trees, balanced fertilization and irrigation should be maintained, following the principle of controlling nitrogen, stabilizing phosphorus, supplementing potassium, and adding trace elements. Using a scientific fertilizer formula helps ensure strong tree growth and improved stress resistance. Especially during the critical period of flower bud differentiation in June, increasing fertilizer application supports both fruit enlargement and bud formation.
Third, pruning during the growing season should focus on suppressing excessive growth to encourage short branch development and flowering. Throughout the season, light pruning techniques such as pinching, not cutting, and reducing heavy cuts are preferred. Before the end of the growing season, removing leaves, shoots, and strong branches, along with redirecting growth direction, helps redistribute nutrients and promote flowering. In summer and autumn, pruning involves cutting back upper, leggy, dense, and competitive branches, which helps conserve energy and improve overall tree health.
Lastly, pest control is vital throughout the growing season, with an emphasis on protecting the leaves. Diseases like early defoliation and brown spot, as well as pests such as the golden moth and two-spotted mite, must be monitored and controlled effectively. A comprehensive and proactive approach ensures that the tree remains healthy and productive.
