Persimmon tree autumn and winter management techniques
The development of persimmon farming offers a promising path for farmers to increase their income, and based on years of experience, proper autumn and winter care plays a crucial role in ensuring healthy growth and high yields. Here are some key practices that should be followed:
First, branch training and pruning. The best time to perform branch pulling is in September. Focus on the main and secondary branches, adjusting the base angle of the main branches to around 90 degrees. If the angle is less than 70 degrees, it should be pulled downward; if more than 70 degrees, pull upward. Ensure the direction is balanced—pull left when needed, and right when necessary. Pruning during winter helps young trees bear fruit earlier, maintains productivity in mature trees, and rejuvenates older ones. Winter pruning is typically done after leaf fall and before spring budding. Adjust the intensity based on tree vigor, soil conditions, and pest issues. If severe infestations like persimmon keratosis or persimmon worms are present, and the tree shows signs of weakness, heavy pruning is necessary. Otherwise, keep it light.
Second, proper fertilization and irrigation. Autumn basal fertilization should be applied between mid to late September and early October, when microbial activity is at its peak, allowing organic matter to break down quickly and be absorbed by the roots. Use mainly organic fertilizers, with supplements like NPK as needed. Water immediately after application. In areas without irrigation, snow can be placed around the tree’s base, and ice blocks can be added to increase moisture levels and help the tree survive the winter.
Third, disease and pest control. Autumn and winter are critical times for managing pests and diseases in persimmon trees. One important step is to remove all diseased fruits, fallen leaves, and dead branches. This helps eliminate overwintering pathogens such as angular spot, round spot disease, and anthracnose, reducing the risk of infection in the next growing season. Additionally, for pests like Shikita and Caesalpina, scrape off the rough bark on trunks and branches, destroy any hanging insect-infested fruits, and remove them properly. Combine this with ground treatments to target overwintering eggs. After scraping, whitewash the trunk to protect it from sunscald and further damage.
By following these practices, farmers can ensure strong, healthy persimmon trees that produce high-quality fruit year after year. Proper care in the off-season not only improves yield but also enhances the long-term sustainability of the orchard.
