What Happens If You Feed Plants Hot Water?

As a plant lover, you may have wondered if the temperature of the water affects the health and growth of your beloved plant. Water is an essential ingredient for plant growth, and the temperature of the water we feed our plants may impact their well-being. Read on to find out what happens if you feed plants hot water.

Hot Water vs. Cold Water

The temperature of water affects plants because it changes the temperature of the soil, which impacts the root system. Hot water can cause the soil to become too hot; likewise, cold water can make the soil too cold. Coldwater can shock the roots, causing them to become vulnerable to disease or damage from soil-dwelling pests. Conversely, warm water can soothe the roots and help nutrient uptake, but hot water can stunt growth and even kill plants.

Effects of Hot Water on Plants

Hot water can scald plant roots, leading to root damage, impaired growth, and even death. When the water temperature exceeds 120°F, it can rapidly increase the water uptake by the plant from the soil. This rapid uptake of water can lead to an oversupply of water in the plant, resulting in root rot for some species of plants. On the other hand, colder water temperatures tend to slow down the water uptake process, and the roots can "keep up" with water uptake more efficiently. In some cases, plants can handle a wide range of water temperatures, but generally speaking, it is best to avoid feeding plants hot water.

The Best Water Temperature for Plants

Temperature is just one factor in making sure your plants are healthy. The best way to feed your plants is to use room temperature water that ranges from 65°F to 75°F. At this temperature range, plants can take in the water and its nutrients without stressing the roots. It is essential to note that when filling a watering can with tap water, the temperature of the water may change throughout the day, so it is recommended to let the water sit out for at least a few hours before feeding your plants.

Exceptions to the Rule

There are some exceptions to the rule, and some plants may benefit from a little warm water. For example, some tropical plants thrive in warm, humid conditions and benefit from regular misting with warm water. Additionally, some seeds require warm water to kickstart germination, such as peas or beans. Finally, for those who cultivate hydroponic plants, still, others might use warm or hot water in their nutrient solutions.

Conclusion

The temperature of water can impact the growth and health of your plants; it is generally recommended to feed plants with room temperature water, which is best for plants' roots. Hot water can scald the plant's roots, causing damage that can become fatal over time. However, some plants may require warm water to grow, such as tropical plants, hydroponic plants, or germinating seeds, in these cases, it is essential to follow specific guidelines for the best results. With the right watering practices, your plants will flourish and thrive under your care.
