Keeping Your Lawn and Plants Healthy in the Summer Heat

During summer’s heat, you may find your lawn and garden looking less than their best. Here we provide tips for what to do, and what not to do, for your lawn and garden to help them stay healthy during summertime.  


It may seem counterintuitive, but regularly dousing your dry, dead-looking lawn and plants with water will do more harm than good. Indeed, this can kill your lawn and plants rather than save them.  

Another common problem is to provide frequent, but shallow watering. This will encourage roots to grow near the surface only, making plants susceptible to heat and drought. 

Instead, provide deep, but sporadic watering. This will help plants root and give them what they need to weather the heat and drought. For more tips, visit our article on timing your watering.  


Simply put, do not fertilize during this time. Indeed, this is one of the worst things you can do because the fertilizer ingredients mixed with hot temperatures can quickly kill your lawn and plants. 

Lawn Care

To begin with, ensure that you are mowing your grass to the correct height. That height can vary depending on the type of grass, but you should allow your grass to grow a bit taller to help shade and cool the soil while also protecting the roots.  

Next, determine whether you will allow your lawn to go dormant by no longer watering. It won’t look good but will be healthy. However, you cannot allow your lawn to go dormant and later try to bring it back. You must wait until cooler temperatures return in the Fall to bring your lawn back to life. 

Likely, though, you will prefer to keep your lawn green during the summer. To do this, water deeply about twice a week to keep your lawn alive and growing. Ensure that you do not miss a watering, though, as your lawn may then go dormant.  

If your grass or patches of it die, though, then you can bring it back. First ensure that your grass is dead, not dormant. If dead, follow our tips on how to revive dead grass.  

Flower and Plant Care

Keeping your plants healthy during summer means using lots of mulch and deep, infrequent watering methods. The mulch helps keep moisture from evaporating, so the plant has time to use it. Mulch should be about two to three inches thick in most garden beds.  

Water early in the morning before the temperature warms up. Early morning watering will ensure that the water will reach the roots but any excess will be gone before nightfall. 

Container plants should receive frequent watering through the hottest, driest part of summer. Water will evaporate quickly and so you must replenish it immediately to keep your plants from withering.
