Light or Heat Source Damage

• Don’t water or mist the plants in the afternoon when the sun is active; it will cause leaf burns.
• Resist the urge to remove partially dead leaves, and especially don't cut too hard. Leaves, dead or alive, will shade foliage that hasn't been burned, and those with some greenery will continue to photosynthesize.
• Water generously. 
• Use drip or soak hoses for more efficient use of water; water is lost due to evaporation when the sprinkler is used.
• Apply the mulch to a depth of 2 to 3 inches. Any organic matter will help retain soil moisture and even out soil temperature.
• Create a shading for plants during the hottest days – for example, cover them with white fabric.

The main key to solving the problem with this disease is the presence of strong root systems in plants. This should help them prepare for the high temperatures that come with summer weather. It is important for gardeners to take preventive measures against heat stress. If your plants are in pots, move them indoors or to an area with shadow. Place temporary shading, such as shade clothing, over plants to keep them cool and block out the sun's rays. Deep water plants first only early in the morning and do not fertilize them during times of heat stress.
