Florida summers can be tough on more than just people. Extended periods of high temperatures, intense sunlight, and limited rainfall can quickly take a toll on your lawn, trees, shrubs, and ornamental plants. Without proper care, heat stress can lead to brown grass, wilted plants, weakened trees, and costly landscape damage.
The good news is that a few proactive steps can help your landscape stay healthy and vibrant, even during the hottest months of the year.
Water the Right Way
When temperatures soar, how you water is just as important as how often. The best time to irrigate is early in the morning, before the sun is high and temperatures begin to climb. Watering during the cooler hours allows moisture to soak into the soil instead of evaporating quickly.
Avoid watering during the hottest part of the day, as much of the water will evaporate before it can benefit your plants. Evening watering can also leave moisture on grass blades overnight, increasing the risk of certain fungal diseases. Deep, infrequent watering is generally more effective than frequent, shallow watering because it encourages deeper root growth and improves drought tolerance.
Watch for Signs of Heat Stress
Even well-maintained landscapes can struggle during periods of extreme heat. Common signs of heat stress include:
- Grass that turns bluish-gray or brown
- Wilting leaves or drooping plants
- Dry, crispy leaf edges
- Premature leaf drop
- Slow or stunted growth
Recognizing these symptoms early allows you to adjust your watering schedule and address problems before permanent damage occurs.
Don’t Cut Your Grass Too Short
Many homeowners think mowing shorter means mowing less often. In reality, cutting grass too low can increase heat stress. Taller grass blades provide natural shade for the soil, helping retain moisture and protect the root system from excessive heat. Follow the recommended mowing height for your grass variety, and never remove more than one-third of the blade during a single mowing.
Mulch Helps More Than You Think
A fresh layer of mulch does more than improve curb appeal. Mulch helps insulate the soil, retain moisture, regulate soil temperature, and reduce weed growth. Organic mulches also break down over time, improving soil quality and providing nutrients for plants. Applying two to three inches of mulch around trees, shrubs, and landscape beds can make a noticeable difference during periods of extreme heat.
Be Careful With Fertilizer
Plants experiencing heat stress are already working hard to survive. Applying too much fertilizer during extremely hot weather can sometimes do more harm than good by encouraging new growth when plants should be conserving energy. A lawn care professional can help determine the best timing and products to keep your landscape healthy without adding unnecessary stress.
Keep an Eye on Trees and Shrubs
Mature trees and established shrubs are generally more resilient than lawns, but they aren’t immune to heat damage. Watch for wilting, scorched leaves, branch dieback, or premature leaf drop. Newly planted trees and shrubs require extra attention because their root systems haven’t fully developed yet. Consistent watering during dry periods helps protect these valuable landscape investments.
Inspect Your Irrigation System
An irrigation system is only effective if it’s working properly. Check sprinkler heads regularly for clogs, damage, or misaligned spray patterns. Make sure every area of your lawn and landscape is receiving adequate coverage without wasting water on sidewalks or driveways. A seasonal irrigation inspection can improve efficiency while ensuring your landscape receives the water it needs. We can help.
