Water Early. This is perhaps the most important thing you can do for your plants during the Oklahoma summer months.
Use Drought-Tolerant and Native Plants. Drought-tolerant and native plants are better adapted to hotter weather and consume less water. Their root structures dig deeper into the soil or they know how to conserve water compared to other plants.
3. Create Shade.
For more heat-sensitive plants, consider putting up shade to protect them from the blaring sun. This could look something like erecting an umbrella or temporary shade to keep them cooler.
4. Don't Forget to Weed.
Plants tend to grow like crazy in hot weather and weeds are no exception. If you don’t manage them during the summer months on a regular basis, then your beautiful landscaping will become overgrown with plants you don’t want.
5. Add a Layer of Mulch. Mulch is your friend during the hot summer months because it adds a protective layer that will keep the temperatures down in the garden bed. The extra layer helps retain the moisture from watering, keeping your plants from getting thirsty more often.
6. Refrain from Cutting the Grass Short.
Keeping your lawn short during the summer months actually causes it to burn. Allowing it to grow at least three inches tall in hot weather will provide shade for the roots and new growth.
