Why watering your plants at midday won't damage their leaves

Описание: It is a long-held idea that midday watering will scorch plants' foliage and damage their health – but this isn’t supported by the evidence, says James Wong

The theory is that tiny water droplets can act like lenses, focusing the sun’s rays onto sections of leaves just like a magnifying glass would, resulting in scorched foliage and reduced plant health.

However, the sun’s intensity at these times is too low to cause any harm. Even if the intense light of the midday sun did somehow come at the most potent angle, the heat at this time of day would invariably cause the water droplets to evaporate before they had an effect.
