Problem Solver: Sunburn and Excessive Heat

In areas where intense sun and heat may scorch your tree, precautions should be taken to reduce damage. Trunks can be wrapped using appropriate materials available at garden supply stores. Another method is to mix a 50:50 solution of white latex paint and water. Use the dilute paint to whitewash trunks and exposed branches. One application is usually sufficient for a summer of sunburn protection.

The roots of potted citrus trees may also become overheated due to excessive sun exposure. One solution is to nest the pot into a larger one which will buffer heat on the roots. Whitewashing the pot with white latex may also be a viable solution in certain circumstances.

Another solution is to provide afternoon shading in the hottest summer months, using shade cloth or a temporary structure.
