How Warm is Too Hot for Pot Plant Water?

Watering your pot plant seems like a simple enough task, but there are some factors to consider when it comes to the temperature of the water you’re using. Water that is too hot can damage your plant’s delicate roots and even cause it to die. So, how warm is too hot for pot plant water? Let’s find out.

The Ideal Temperature Range

The ideal temperature range for pot plant water is between 65°F and 75°F (18.3°C and 23.8°C). Water within this range is not too hot and not too cold, making it the perfect temperature for your pot plant’s roots to absorb the water and the nutrients it contains. If you’re like most people, you probably don’t have a thermometer on hand when you’re watering your plants, but you can get a good idea of the temperature of your tap water by feeling it with your hand.

Watering with Hot Water

Water that is too hot can cause heat shock to your plant’s root system, which can lead to root damage or even death. If the water coming out of your tap is too hot to comfortably touch, it’s best to wait a few minutes until it cools down before using it to water your pot plants. Alternatively, you can cool the water down by adding some room temperature water to it before watering your plants.

Watering with Cold Water

Water that is too cold can also harm your pot plant by slowing down the plant’s metabolic processes. This can lead to stunted growth, nutrient deficiencies, and even plant death. If the water coming out of your tap is very cold, you should let it sit for a while to come to room temperature before using it to water your plants.

The Bottom Line

When it comes to watering your pot plants, the temperature of the water you’re using is just as important as the frequency and amount of water you’re giving your plants. Remember to test the temperature of your tap water with your hand before using it to water your plants, and if it’s too hot or too cold, wait until it reaches a suitable temperature before using it. By taking care to use water that is not too hot or too cold, you’ll help your pot plants thrive and grow into healthy, vibrant specimens.
