5 Tips for Caring for Plants During Charleston’s Summer Heat

Even the toughest plants need a little extra care when the temperatures soar. Here are five essential tips to help your landscape beat the heat:
​

1. Water Deeply and Early
   Water in the early morning to reduce evaporation. Aim for less frequent but deep watering to encourage strong root systems.
   
   
2.  Add a Layer of Mulch
   Mulch helps retain soil moisture, regulate temperature, and reduce weed competition. Apply 2–3 inches around your plants (but keep mulch away from trunks and stems).
   
   
3. Watch for Signs of Stress
   Wilting, scorched leaves, or leaf drop can be signs your plants are struggling. Adjust your watering schedule or provide temporary shade to help them recover.
   
   
4. Avoid Fertilizing During Peak Heat
   Fertilizing in mid-summer can stress plants and encourage new growth that may burn in the heat. Wait for a break in the weather or fertilize earlier in the season.
   
   
5. Plan Ahead with the Right Plants
   Choose heat-tolerant, Charleston-tested varieties like the ones above to set your landscape up for success. Right plant, right place = happy plants all summer long.
