What should I do with apple trees in spring if they have been gnawed by mice? - briefly
Remove all gnawed bark and shoots, then encircle the trunk with steel‑wool or a protective guard and set baited traps to prevent further feeding. Apply a balanced fertilizer and maintain regular watering to stimulate healthy spring growth.

Inspect the trees early in the season. Identify all damaged bark, shoots, and roots. Remove any dead or severely gnawed tissue with clean, sharp pruning shears, cutting back to healthy wood at least 2 cm beyond the injury. Disinfect tools between cuts to prevent pathogen spread.
Clear the area around each trunk. Gather fallen fruit, twigs, and leaf litter that could serve as food or shelter for rodents. Compost or destroy the material away from the orchard.
Apply a physical barrier to protect new growth. Wrap trunks with a 4–6 mm thick hardware cloth or metal mesh, overlapping edges by at least 5 cm and securing with staples. Ensure the barrier extends from the ground to a height of 1.5 m and is anchored firmly.
Introduce deterrents. Sprinkle rodent‑repellent granules (e.g., powdered garlic or predator urine) along the base of each tree. Reapply after heavy rain. Install motion‑activated ultrasonic devices if local regulations permit.
Set up trapping or bait stations. Place snap traps or live‑catch traps at least 1 m from the trunk, baited with peanut butter or sunflower seeds. If using poison baits, follow label instructions strictly and keep them out of reach of non‑target wildlife.
Promote natural predators. Encourage owls, hawks, and beneficial insects by installing nesting boxes and maintaining habitat diversity around the orchard.
Monitor progress weekly. Record new gnaw marks, stem vigor, and any signs of secondary infection. If fungal symptoms appear, treat with appropriate fungicide according to label rates.
Plan for the next season. After harvest, remove all residual fruit and debris promptly. Consider planting resistant apple varieties and rotating crops to reduce rodent attraction. Implement a regular spring inspection routine to catch damage before it escalates.
