The Case for Early Morning Plant Watering

If you live in an area with hot weather, you might be wondering what the best time of day is to water your plants. After all, you don’t want to water them during the heat of the day, when the sun is at its strongest and evaporation is at its highest. However, you also don’t want to water them at night, when they are more susceptible to fungal diseases. So, what’s the best time to water your plants? The answer is early in the morning, before the sun gets too strong. Here’s why:

1. Cooler temperatures = Less evaporation

When it’s cooler outside, there is less evaporation, which means that more of the water you apply to your plants will be absorbed by their roots. In hot weather, on the other hand, a lot of the water you apply will simply evaporate into the air before it has a chance to reach the roots.

2. Leaves are dryer in the morning

Another reason to water your plants in the morning is that their leaves will be dryer. If you water them at night, their leaves will stay wet all night long, which makes them more susceptible to fungal diseases. Morning watering also gives the leaves a chance to dry out before nightfall, which further reduces the risk of disease.

3. Plants can absorb water more efficiently in the morning

Plants can absorb water more efficiently in the morning because they are actively transpiring (releasing water vapor into the air). This process helps to cool the plant and regulate its internal temperature. As such, watering in the morning allows plants to make better use of the water you apply.

So there you have it! Three good reasons to water your plants in the morning instead of at night. Not only will they lose less water to evaporation, but they’ll also be less likely to develop fungal diseases and they’ll be able to make better use of the water you apply. So next time you’re wondering when the best time to water your plants is, remember: early morning is always best!

  2. Reduce Transpiration.
  3. Limit Runoff.
  4. Store Water in the Soil.

How do you grow a drought garden?
