TL;DR
Heat-stressed plants need careful treatment to recover without overwatering. This article outlines five proven steps, including soil moisture checks, mulching, and providing shade, to help plants survive high temperatures effectively.
Gardeners can now follow five proven steps to help heat-stressed plants recover without overwatering, according to recent expert guidance. Proper treatment is crucial as high temperatures above 85°F can cause plants to wilt and sunburn, increasing their vulnerability to pests and diseases. Learn how to water container plants in June without overwatering.
When plants show signs of heat stress, such as wilting or sunburn, the first step is to check soil moisture before watering. Using a soil moisture meter or performing the finger test can prevent overwatering, which can worsen plant health. Adding mulch around the base of plants helps retain soil moisture and keeps roots cool, reducing heat stress. Providing shade with cloths or relocating container plants to shadier areas protects foliage from sunburn and helps lower temperatures. Fertilizing during heatwaves should be avoided, as it can stress plants further and cause sunburn. Lastly, harvesting ripening fruits and deadheading faded flowers can conserve plant energy, allowing recovery and continued growth.

Experts recommend soil moisture checks, mulching, providing shade, and avoiding fertilization during heatwaves. These practices are increasingly important as climate change results in more frequent and intense heat events, making heat stress management a key aspect of summer gardening.
