Outdoor plants have the potential to thrive in a variety of climates and environments, but they can also be easily damaged by extreme temperatures. This includes both excessively hot and cold temperatures. Cold water is often used to cool down outdoor plants during hot days, but it is important to understand the effects of cold water on outdoor plants before doing so.
Effects of Cold Water on Outdoor Plants
When cold water is applied to an outdoor plant, it will cause the plant’s cells to shrink. This can cause damage to cell walls, reducing their ability to absorb nutrients from the soil and reduce their ability to photosynthesize. In extreme cases, cold water can even cause frost damage or death of the plant.
How Cold is Too Cold?
The exact temperature at which cold water becomes dangerous for outdoor plants depends on the climate and type of plant. Generally speaking, temperatures below 60°F (16°C) are considered too cold for most outdoor plants. If you plan on using cold water on your outdoor plants, it’s best to avoid temperatures below 50°F (10°C).
What Should You Do Instead?
If you need to cool down your outdoor plants in hot weather, there are several things you can do instead of using cold water. Adding mulch around the base of your plants can help keep them cool in warm weather.
Additionally, you can cover your plants with a light material like burlap or cheesecloth during especially hot days.
Conclusion: Is Cold Water Bad for Outdoor Plants?
In short, yes – cold water can be bad for outdoor plants if it is too cold or if it is used too often. When using cold water on your outdoor plants, it’s best to avoid temperatures below 50°F (10°C) and make sure that you are not over-watering them.
