Most plants suffer when the weather turns hot enough for a certain period of time. It causes irreversible damage by way of plant function or development. This isn’t merely droopy leaves in the heat of the afternoon; it’s things like stunted growth, leaf drop, leaf scald, failure to flower, or failure to produce seeds.
Can plants recover from too much heat?
Plants partially welt as a technique to conserve water and reduce moisture loss from their leaves when exposed to intense sun, even if they are well hydrated. In most instances, the plants fully recover after the sun has set or once they are in shade without additional water.

The best time to water plants is in the morning or evening.
Morning watering is actually preferable to evening watering as the plant has time to dry before the sun goes down. At night, water tends to rest in the soil, around the roots, and on the foliage, which encourages rot, fungal growth, and insects.
When should you water plants when its hot?
In the current hot breezy weather it is probably best to water in the early evening. This gives the plants enough time to dry out, but there is still the chance for overnight water uptake by the roots. And if you want to water in the morning then start very early – before the sun is shining.

Answer: Early morning (5:00 to 9:00 am) is the best time to water the garden when using a sprinkler, garden hose, or any other device that wets the plant foliage. When watering is completed, the plant foliage dries quickly. The rapid drying of plant foliage helps guard against the development of fungal diseases.

How do plants survive heat stress?
Plants have a heat shock response (HSR), which is activated via fluidity changes in the plasma membrane and heat-responsive cyclic nucleotide-gated ion channels (CNGCs), which use Ca2+ and reactive oxygen species (ROS) as messengers to mediate a signaling pathway, leading to the upregulation of heat-induced mRNA in
