Why Watering Plants in the Sun Can Be a Bad Idea

For many plant enthusiasts, watering plants in the sun seems like a natural thing to do. However, this is not always the best approach, and may even harm your plants in certain circumstances. In this article, we’ll explore why watering plants in the sun can be a bad idea.

The Sun Can Cause Water to Evaporate Too Quickly

One of the main reasons why watering plants in the sun can be a bad idea is that the sun’s rays can cause water to evaporate too quickly. This means that even if you water your plants thoroughly, the water may not be able to penetrate the soil deeply enough to reach the roots. As a result, your plants may not get sufficient water, which can lead to wilting, stunted growth, and other issues.

Water Droplets Can Act Like a Lens

Another issue with watering plants in the sun is that water droplets can act like a lens, focusing the sun’s rays onto leaves and potentially causing damage. This is particularly true if the water droplets are left on the leaves for an extended period of time, as the concentration of sunlight can increase over time. In some cases, this can even lead to sunburn or scorching of the leaves, which can cause long-term damage to your plants.

Sunlight Can Heat Up the Water to Uncomfortable Temperatures

Another potential issue with watering your plants in the sun is that the sunlight can heat up the water to uncomfortable temperatures. This may not be an issue in some cases, but if the water gets too hot (above 80 degrees Fahrenheit), it could actually harm your plants. This is especially true for plants that prefer cooler temperatures, such as many types of houseplants.

What to Do Instead

So, if watering plants in the sun can be a bad idea, what should you do instead? Well, one option is to water your plants early in the morning or in the evening, when the sun’s rays are less intense. This will help to minimize evaporation and ensure that your plants get sufficient water. Alternatively, you could use a watering can or a drip irrigation system, which will allow you to water your plants more slowly and deeply.

Conclusion

In conclusion, while it may be tempting to water your plants in the sun, doing so can be a bad idea in many cases. The sun’s rays can cause water to evaporate too quickly, water droplets can act like a lens and cause damage, and sunlight can heat up the water to uncomfortable temperatures. Instead, it’s best to water your plants early in the morning or evening, or to use a watering can or drip irrigation system to ensure that your plants get sufficient water.
