Water Plants in the Morning

By Brian Clark Howard

The best time to water plants is usually in the morning, both to maximize the efficiency of H₂O used and to promote healthy flora.

Mornings tend to be cool and without strong winds, so the amount of water lost to evaporation is much less than during the middle of the day. Yes, evenings are typically similar, but if plants stay damp over night they are more likely to be damaged by fungal and bacterial diseases. Ideally, use a drip or soak system instead of a regular sprinkler, which wastes a lot of water and drenches the leaves, which are prone to damage as well as disease.

Most experts recommend substantial, infrequent watering for established plants, typically a total of about one inch of water per week (including rain). One or two applications a week encourages deeper rooting, which promotes stronger plants. To avoid shocking tender greenery, try to use water at or near air temperature (collected rainwater is best).

With population growth and climate change putting increasing pressure on freshwater supplies, it is becoming more important than ever to save water.
