Protecting Avocado Trees from Sun Damage

During the hottest months of the year sun damage is a concern, prolonged exposure to intense sunlight can lead to sunburn, stress. In this post, we go over simple yet effective ways to prevent sun damage in avocado trees.

Proven Ways to Prevent Sun Damage

1. Shade Young Trees

Newly planted or young avocado trees often need extra help adjusting to direct sunlight. Providing temporary shade using shade cloth can significantly reduce the risk of sunburn. Be sure to allow for airflow.

2. Whitewash the Trunks

Painting the trunks with a mixture of water and flat white latex paint is a tried-and-true method for reflecting sunlight and reducing bark temperature. This is especially helpful after pruning or if the tree is exposed to more sun than usual.

3. Use Surround WP

Surround WP is a powder that, when mixed with water and used as a spray, coats leaves and bark in a protective, reflective layer. It helps reduce leaf temperature and prevents sunscald. Apply it in early summer and reapply after heavy rains.

4. Mulch for Moisture and Insulation

Apply organic mulch around the base of the tree to help retain soil moisture, reduce heat stress on the roots, and moderate soil temperature.

More Tips

Gradual Exposure: If moving trees from shade to full sun (such as in transplanting), do so gradually over a few weeks.

Avoid Over-Pruning: Pruning too much at once can expose previously shaded bark and branches to sudden sun, increasing the risk of burn.

Monitor Regularly: Keep an eye on your trees during heatwaves and dry spells. Early signs of sunburn can often be reversed with prompt action.

By taking preventive measures like shading, whitewashing, spraying with Surround WP, and mulching, you can shield your avocado trees from the harmful effects of intense sunlight. A little protection goes a long way in ensuring your trees grow strong and healthy.
