Heat Wave Watering Guide – How Much To Water During Heat Waves

It’s hot enough to fry an egg on the sidewalk—imagine what it’s doing to your plants’ roots! It’s time to step up your watering efforts, but just how much should you increase it? Learn about watering during heat waves and tips for keeping plants safe in high temperatures in this article.

Watering During Extreme Heat

When the temperature soars, it might seem like a good idea to grab a cold drink, relax, and enjoy the air conditioning, but don’t forget your plants! When it’s hot for you, it’s hot for them too. Watering during a heat wave is crucial to keep your plants from wilting. But how much should you water?

The answer isn’t simple—it depends on the plant type, air temperature, and soil type. Potted plants add another layer of complexity. Plants show signs when they need water. For instance, if a plant looks fine in the morning but droopy by mid-afternoon, it needs water. If your vegetable garden stops growing suddenly, it needs water. If your hanging baskets dry out between waterings, they need more water. Whether you hand water or use soaker hoses and irrigation systems, consistency is key.

To figure out the right amount of water, try this method: Water your plants as you think they need, then check the soil about 30 minutes later by digging a hole 8 inches (20 cm) deep. If the soil is moist but not wet, you’ve got it right. If it’s dry, water more. If it’s very wet, water less and improve your drainage for the plants’ future health.

Additional Tips for Keeping Plants Cool During a Heat Wave

Watering isn’t the only thing you can do to keep your plants cool. Here are a few more tips:

• Mulching: Apply mulch around your plants to help retain moisture and keep roots cool.
• Shading: Use shade cloths or other materials to provide temporary shade during the hottest parts of the day.
• Water Timing: Water early in the morning or late in the evening to reduce evaporation and allow plants to absorb water more effectively.
• Monitor and Adjust: Keep an eye on your plants and adjust your care routine as needed based on their responses to the heat.

By following these tips, you can help your plants survive and thrive even in extreme heat.
