What are the best treatments to protect cedar outdoor tree boxes from pests?

Cedar outdoor tree boxes are a beautiful and durable addition to any garden, but they can be vulnerable to pests like termites, beetles, and fungi. To protect them, consider these effective treatments:

1. Natural Oils: Apply cedar oil or neem oil, which act as natural repellents against insects without harming the wood.

2. Wood Preservatives: Use borate-based solutions to prevent termite and fungal infestations while being safe for plants.

3. Sealants and Stains: Waterproof sealants or UV-resistant stains create a barrier against moisture and pests.

4. Physical Barriers: Install metal mesh or gravel around the base to deter burrowing insects.

5. Regular Maintenance: Inspect and clean the boxes periodically to catch early signs of damage.

By combining these methods, you can ensure your cedar tree boxes remain pest-free and last for years.
