- Check that all the trunk parts of citrus and young trees that are exposed to the sun are painted white. This keeps them cooler and protects them from sunburn. Use white latex paint diluted with water (1 volume white flat latex paint for 1 volume water).
- Cut your grass higher (2 to 3 inches) to decrease the water use.
- Check your drip watering system. Verify the ground humidity around all plants. Check your drippers every other day to see if any popped out now that heat is making the hoses softer.
- Plant pumpkin, winter squash.
