Can you water plants in the heat of the day?
The "Leaf Burn" Myth:
It is a common misconception that water droplets act as magnifying glasses and scorch leaves in the sun. You will rarely cause plant damage by getting foliage wet, though it can promote fungal disease in humid climates.
The Ideal Times:
Early morning is the best time to water, as cooler temperatures and low winds minimize evaporation. Late evening is the second best, but try to water the soil directly so leaves aren't left damp overnight, which invites slugs and diseases.
How to Water in the Heat: Focus your watering at the base of the plant (the soil) where the roots can actually drink it. If you use a hose that has been sitting in the sun, let it run for a few minutes until the water turns cool before spraying.
Protecting the Soil:
Apply a 2 to 4-inch layer of mulch around your plants to help the soil retain moisture during severe heat waves.
So yes, it is perfectly fine to water plants during the heat of the day if they are actively wilting or severely dry. However, it is not the ideal time because significant water is lost to evaporation, meaning your plants won't get as deep a drink.
