When to Water Plants During a Heat Wave

During a heat wave, it can be challenging to keep plants hydrated. High temperatures and dry air cause soil to dry out quickly, which can stress plants and even lead to their death. Knowing when and how to water your plants is essential to keep them healthy during a heat wave.

Watering Techniques

Watering your plants early in the morning or in the evening when the temperatures are cooler will help prevent evaporation and allow your plants to absorb water more efficiently. Avoid watering your plants during the hottest part of the day, as the water will evaporate quickly and not reach the roots effectively.

It is also essential to water the soil, not the foliage. Wet leaves during the hot sun can cause scorching and damage to the plant's foliage.

Watering your plants thoroughly and deeply will allow the water to reach the plant's roots, which will encourage the roots to grow deeper and allows the plant to better withstand drought conditions. A deep watering session of around 30-60 minutes every three to four days is recommended during a heat wave.

How to Test for Dry Soil

It is essential to water your plants when the soil is dry. However, how do you know when the soil is dry? One method is to use your finger to check the moisture level of the soil. Stick your finger about two inches into the soil around the plant. If the soil is dry, it's time to water the plant.

Another method is the weight test. Pick up a pot or container and feel its weight when it's fully watered, then pick it up again when it's dry. This strategy will help you get a sense of when to water the plants to avoid over or under-watering.

Signs of Overwatering

During a heatwave, overwatering plants can cause root rot and weak growth. Keep an eye out for signs of overwatering, such as yellowing or wilting leaves. If you notice these signs, reduce the amount and frequency of your watering sessions.

Signs of Underwatering

If you notice your plant's leaves are turning brown, dry, or crispy, this is a sign of underwatering. The soil around your plant may also appear hard and cracked. In this situation, increase the frequency and amount of watering sessions to prevent the plant from wilting and dying.

Conclusion

During a heat wave, it's essential to monitor and adjust your watering techniques to keep your plants healthy. Remember to water early in the morning or in the evening, water the soil, not the foliage, and water deeply and thoroughly. Use the finger or weight test to decide when your plant needs water, and be aware of the signs of over and underwatering. Follow these tips, and your plants will flourish throughout the hot summer months.
