Plum Harvest Consequence Park Management Points
After harvesting your peaches, it's crucial to take proper care of the trees to ensure their health and productivity for the next season. Here are five essential post-harvest practices you should follow:
**1. Fertilization**
Once the fruit is picked, it’s important to fertilize the tree promptly. This helps restore its energy and strengthen its overall vigor. The primary type of fertilizer needed is nitrogen-based. The amount of fertilizer should be adjusted depending on the tree’s size and the previous year’s yield.
**2. Pest Control**
Pest management after harvest is critical to prevent damage that could affect next year’s crop. Several pests are common during this time:
- **Peach Leafhoppers**: These insects feed on leaves, causing them to turn gray and eventually fall off. From August to September, they become most active. To control them, first spray the tree with a broad-spectrum fungicide, then apply 50% malathion diluted at 1,000 times or 40% acephate at 1,000 times. This helps suppress egg-laying and reproduction.
- **Leaf Spot Disease**: This fungal disease affects leaves and shoots. It’s common in plum orchards. To manage it, use 75% chlorothalonil diluted at 700 times. Adding a new high-fat film can enhance the effectiveness of the treatment.
- **Mulberry Caterpillars**: These pests are active in early August and again in mid-September. Apply 40% acephate EC diluted at 1,000 times mixed with 95% paraffin oil emulsion at 150 times. Adding a high-fat film can help overcome resistance and improve control.
- **Moth and Butterfly Larvae**: These larvae feed on leaves. Inspect the tree regularly after harvest and treat any infestations immediately.
- **Red Spider Mites**: Active in late summer, these mites cause leaf discoloration. Use 5% abamectin EC diluted at 1,500 times combined with 73% tebufenozide EC diluted at 2,000 times. In severe cases, add a high-fat film to boost efficacy.
**3. Pruning**
Prune the tree after harvest to improve air circulation and light penetration. Remove competing branches, dense growth, and leggy shoots. Focus on thinning the outer and upper parts of the canopy. If the tree is too crowded, consider cutting back some large branches. Pruning reduces nutrient consumption, improves photosynthesis, and promotes better flower bud development for the following spring.
**4. Soil Cultivation**
In September, perform deep plowing to a depth of 20–30 cm. This improves soil structure, enhances root activity, and increases the tree’s ability to absorb water and nutrients. It also strengthens the tree’s resistance to drought, poor soil, and pests, while boosting its photosynthetic efficiency.
**5. Applying Base Fertilizer**
Along with deep plowing, apply a base fertilizer in September. This is a key step in ensuring steady production and high yields. Combining base fertilizer with deep cultivation helps improve soil quality and root absorption. The fertilizer will be available for the roots before the leaves fall, aiding in root recovery and growth. It also supports better leaf function and nutrient storage, which benefits the tree’s performance in the coming year.
By following these steps, you’ll give your peach trees the best chance to recover and thrive, setting the stage for a successful harvest next season.
