- Watering in the morning will help maximize water uptake needed for plants to survive the heat. Watering during a heat peak can increase evaporation causing water in the soil to be unavailable for the plant.
- Prune or trim plants lightly during summer months. By leaving enough foliage to cover the base of a plant, you will prevent sunburn on the stem and other parts needed for plant health. Foliage will also act as insulation to the plant’s root zone causing water in the soil to be less prone to evaporation.
- Prevent over-fertilizing. Over-fertilizing will force the plant to work harder on initiating new growth instead of focusing on surviving a heatwave.
- Shade cloths will also help with heat stress. Covering plants to prevent direct sun exposure can improve the plant’s ability to survive a heatwave. Although this practice is used on nonnative plants, it is often seen on native plants that are in extreme heat stress. Temporarily covering plant will help the leaves recuperate and bounce out of stress.
- Walk garden or yard periodically and inspect irrigation. In some cases, one day of no irrigation can cause a plant to go into stress. Always look for moisture patterns on soil surface and make sure to adjust run times when needed.
- When on vacation always have someone walk your property this will insure that any potential problems are caught on time.
See you soon,
