Do you know the worst times and the best time to water plants in hot weather? It may sound simple but watering your garden at the right times can play a major factor. If you live in a region where the weather is significantly warm in Summer you need to read this.

Watering Myth Debunked

You may have heard somewhere that watering plants in the morning can scorch them. This is a common myth and we’ll explain why. This once-believed theory behind why watering your plants when it’s hot is bad for them was thought to be that the sun’s focus on water droplets intensifies leaving plants susceptible to scorching.

The truth is even in hot climates, the sun doesn’t have this level of intensity. In fact, areas where the heat is really intense during Summer will result in evaporation long before water droplets can cause scorching. That being said, it’s still not an ideal time to water plants when the sun is at its peak.

Watering Guide

There are two prime times to water your garden. For outdoor gardens and flowerbeds the best time to water plants is either early morning or late evening. Watering first thing in the morning gives your plants enough time to absorb water as it reaches the roots before the heat results in evaporation. It also allows plants to handle heat better as water is available throughout the day.

If mornings aren’t ideal due to busy schedules the next best time to water plants is late afternoon or evening. By this time the sun it’s beyond the hottest point of the day and plants will be able to take in water before it evaporates. Watering at either of these times is also more pleasant for you as you’re not dealing with the oppressive heat.

Late Evening Watering

There is a rule of caution when watering late in the afternoon. Do so while there is still enough daylight left for plant leaves to dry before nightfall. When leaves remain damp at night they become more susceptible to fungi growth. This is the powdery mildew you might find on leaves of plants and it can be harmful to your garden.

If you happen to miss that time frame and it’s close to nightfall use a watering can with a spout for direct target watering. Water plants at the base of the stem to avoid getting the leaves wet. Avoid oversaturation as there will be no sunlight to evaporate or dry out the soil.

Create a Watering Schedule

An easy way to ensure your plants receive the required watering they need is to stick to a schedule. If your plants require frequent watering choose the ideal time that works best with your schedule (morning or afternoon). If you have a large garden or landscape you can install a watering system and set a timer to a set schedule for convenience. Just be mindful of the weather and adjust the timer accordingly during periods of heavy rain.
