The Best Time of Day to Water Garden Plants

It’s no secret that plants need water to survive. But did you know that when you water your plants can be just as important as how much water they’re getting? That’s right; the time of day that you water your garden plants can make a big difference in their health and growth.

In this blog post, we’ll explore the best time of day to water garden plants so that you can get the most out of your gardening efforts.

Why Does Timing Matter?

Watering your plants at the right time of day can help them better absorb the moisture they need to thrive. When watering during the daytime, evaporation can cause up to 30% of the water you apply to be lost before it ever reaches the roots of your plants. Watering in the evening or at night can help reduce evaporation and give your plants a chance to slowly absorb the moisture they need.

Additionally, watering in the evening or at night can help reduce the chances of fungal diseases developing on your plants. Fungal diseases like powdery mildew and gray mold love warm, humid conditions. By watering in the cooler evenings, you can help create conditions that are less favorable for these diseases to take hold.

When is the Best Time to Water?

The best time to water your garden plants is in the evening, after the sun has gone down and things have cooled off a bit. If you can’t water in the evening, early morning is also an acceptable time to water. Avoid watering during the middle of the day if at all possible, as this will only contribute to water loss due to evaporation.


By following these simple tips, you can help ensure that your garden plants are getting all the moisture they need to thrive. Watering in the evening or early morning will help reduce evaporation and give your plants a chance to better absorb moisture. And by avoiding midday watering, you can further reduce evaporation and help prevent fungal diseases from developing on your plants.
