Late Management of Middle-early Apple Orchards

The comprehensive management of an orchard should be carried out throughout the entire growth cycle of fruit trees, regardless of the season. However, I have noticed that many apple growers tend to neglect post-harvest care, especially for medium-early maturing varieties. They often believe that once the fruit is sold, their work is done, and some even leave the orchard untouched. This mindset is particularly problematic in seasons with unusual weather conditions, such as the summer droughts we experienced this spring and summer. To address these issues, I strongly recommend focusing on the following key areas: First, pest control. After periods of continuous rain, the risk of pests and diseases increases significantly. It's crucial to monitor for fruit rot, borers, and red spider mites. Early detection is essential—small lesions can be treated with a 200–300 times dilution of Guinness + Roushuitong, applied every 5–7 days using a small brush. For larger lesions, cutting the affected area first and then applying the solution is more effective. In cases of brown spots or red spider infestations, spraying with 5000–6000 times diluted Guinness + Roushuitong mixed with Abamectin at 3000–4000 times is recommended. Second, nutritional supplementation. After harvest, trees are depleted of nutrients, so it's important to provide them with a balanced dose of nutrition. A combination of fruity friend amino acid and ginkgo extract is ideal—it supports both recovery and disease prevention. Third, field management. Once the fruit is harvested, the tree’s energy shifts, and new shoots begin to grow. This period is critical for managing early-maturing apple trees. For medium-early varieties, pruning and training during late May to early June (spring shoots) and late July to early August (summer shoots) is essential. However, many growers overlook the importance of autumn shoot growth, which, though short, plays a vital role in nutrient accumulation. Neglecting this phase can lead to poor flower bud formation and reduced yields the following year. Proper pruning techniques are key. For example, removing overlapping branches after mid-August helps control the canopy and stabilize tree vigor. Autumn growth heals quickly, making it a good time for major pruning. Back branches should be managed carefully—strong ones should not be removed, while weaker ones can be redirected or pruned to encourage renewal. Similarly, main and lateral branches should be pruned gradually to avoid shocking the tree. Fourth, branch transformation. If any branches haven't been properly trained, mid-August is an ideal time to start. The rapid growth during this period allows for quick healing. However, medium-early varieties typically have poor wound healing, so any cuts should be wrapped in plastic film immediately to prevent dieback. Fifth, applying autumn basal fertilizer. As the fruit trees enter their third root growth peak in September, it's the perfect time to apply organic fertilizers like cooked chicken manure or sheep dung—ideally less than 3,000 pounds or 20 bags of dry manure. Avoid overusing chemical fertilizers, and apply them at a depth of about 20 centimeters for optimal absorption. In conclusion, post-harvest management is just as important as pre-harvest care. With proper attention to pest control, nutrition, pruning, and fertilization, growers can ensure healthier trees, better yields, and long-term sustainability.
