Citrus management after freezing should keep up

<

Since mid-January, the Yangtze River valley has experienced a sharp drop in temperatures, with minimums falling below -4°C. Prolonged freezing conditions, often accompanied by rain and snow, have caused serious frost damage to citrus trees. Especially during dry spells or light drizzle, the combination of cold and dryness leads to "dry freezing," which severely affects tree health. If timely recovery measures are not taken, this could result in a significant decline in citrus production this year. To help citrus trees recover after the freeze, several key management practices should be implemented: **Water Spraying to Reduce Stress** Once the weather clears up after a freeze, spraying water on the trees can help slow down the temperature rise and reduce rapid thawing. This also helps minimize leaf water loss, preventing further damage. After the sun comes out, covering the canopy with straw or other materials can protect the trees from direct sunlight, allowing them to thaw gradually and reducing stress. **Soil Cultivation for Root Recovery** As soon as the soil thaws, it’s important to loosen the top 10–15 cm of soil around the trees. This improves aeration, warms the soil, and encourages root activity, helping the trees regain their vitality. In drier areas, watering is essential to replenish moisture and support both roots and foliage. This practice can also help reduce the impact of the freeze. **Fertilization for Tree Restoration** After a freeze, citrus trees often suffer weakened functions. If the canopy is heavily damaged, applying quick-acting nitrogen fertilizers and foliar sprays (like urea, zinc, and boron) can promote new growth and speed up recovery. Manure or urea can be applied directly to each tree, and foliar sprays should be repeated every 10–15 days to ensure optimal results. **Pruning Based on Damage Severity** Post-freeze pruning should be done in mid-March, depending on the extent of damage. Trees with mild damage should be pruned minimally to preserve leaves and maintain yield. For moderate damage, dead branches should be removed to encourage new growth. In cases of severe damage, frozen main branches may need to be cut back, and the cuts should be sealed with wax or fungicides like Bordeaux mixture or carbendazim to prevent infection and stimulate new shoots. **Pest and Disease Control** Frost-damaged citrus trees are more vulnerable to pests and diseases, especially resin disease. A mixture of asphalt, diesel, and water can be used to treat affected areas, along with proper scraping before application. Controlling anthracnose and spider mites is also crucial. Additionally, protecting the trunk from sunburn with lime water mixed with yellow mud and cow dung can help prevent further damage and support the tree’s recovery. By following these steps, citrus growers can significantly improve the chances of their trees recovering and producing a good harvest this season.
