Protect Your Tennessee Lawn From Heat, Drought, Disease, and Preventable Mowing Damage
Tennessee summers bring high temperatures, humidity, and periods of limited rainfall. As a result, even healthy lawns can begin to show signs of stress.
A successful summer lawn care Tennessee routine requires more than regular mowing and occasional watering. Homeowners must also consider their grass type, soil conditions, and current weather.
Tennessee sits in a transition zone where both cool-season and warm-season grasses are common. However, these grasses respond very differently to summer weather. Tall fescue may thin or turn brown during prolonged heat. Meanwhile, Bermuda grass and zoysia usually grow most actively during summer.
Avoiding the following seven mistakes can help protect your lawn throughout the hottest part of the year.
1. Treating Every Type of Grass the Same
One of the most common mistakes is following the same routine for every lawn.
Tall fescue is a cool-season grass. Therefore, it grows best during spring and fall. Summer heat can slow its growth and increase stress.
Bermuda grass and zoysia are warm-season grasses. In contrast, they grow actively during late spring and summer. They may need more frequent mowing while temperatures remain warm.
Before making major changes, identify the grass growing on your property. This will help you choose the correct mowing height, watering schedule, and fertilization plan.
It is also possible to have more than one grass type on the same property. For example, tall fescue may grow in shaded areas while Bermuda grass spreads through sunnier sections.
2. Mowing the Lawn Too Short
A closely cut lawn may look neat at first. However, mowing too short can place additional stress on the grass.
Longer grass blades provide more shade for the soil. They also help protect the crown of the plant from intense sunlight. In addition, taller turf can support a stronger root system and improve access to soil moisture.
During summer, raising the mowing height can help protect the lawn from heat and moisture loss. Tall fescue should generally remain taller than warm-season grass varieties.
The correct setting will depend on the grass variety and equipment. Still, lowering the mower simply to extend the time between visits can damage the lawn.
3. Removing Too Much Grass at Once
Waiting too long between mowings creates another problem. When the grass becomes overgrown, homeowners may remove several inches in one visit.
Instead, follow the one-third rule. Avoid removing more than one-third of the grass blade during a single mowing.
Removing too much can shock the plant. As a result, the lawn may look yellow, thin, or uneven after mowing. Scalping can also expose the soil to more heat and encourage moisture loss.
During periods of rapid growth, Bermuda and zoysia may need more frequent mowing. However, tall fescue may grow more slowly during extreme heat. Therefore, the mowing schedule should follow the lawn’s growth rather than a rigid calendar.
4. Watering Lightly Every Day
Frequent shallow watering may seem helpful during hot weather. Unfortunately, it can encourage roots to remain close to the soil surface.
Those shallow roots dry out more quickly. Consequently, the grass becomes less prepared for heat and drought.
Instead, water deeply and less frequently. This encourages moisture to move farther into the soil. It can also help the lawn develop a stronger response to dry conditions.
Avoid watering automatically simply because the weather is hot. First, check for signs of drought stress. These may include:
- Grass blades that begin to curl
- A dull or gray-green appearance
- Footprints that remain visible after walking
- Areas that do not spring back after being pressed
Also, remember to account for rainfall. Irrigation systems should be adjusted after storms so the lawn is not watered unnecessarily.
5. Watering at the Wrong Time
The time of day matters almost as much as the watering method.
Watering during the hottest part of the afternoon can result in greater evaporation. Therefore, less water may reach the root zone.
Evening watering can create a different problem. Grass blades may remain wet throughout the night. Prolonged moisture, warm temperatures, and poor airflow can create favorable conditions for lawn diseases.
Early morning is usually the best time to irrigate. Temperatures are cooler, and the lawn has time to dry as the day progresses.
Also, check sprinkler coverage regularly. A damaged sprinkler head or poorly positioned nozzle can leave some areas dry while oversaturating others.
6. Applying Fertilizer Without a Plan
Fertilizer is not always the solution to a struggling summer lawn.
Applying too much fertilizer can increase stress and create excessive growth. It may also raise the risk of fertilizer burn during hot, dry conditions.
More importantly, fertilization timing depends on the grass type.
Warm-season grasses such as Bermuda and zoysia actively grow during summer. Therefore, they may benefit from properly timed fertilizer applications based on soil conditions.
Tall fescue is different. Heavy summer fertilization can push new growth while the grass is already struggling with heat and humidity. Instead, major feeding for tall fescue is generally better suited to its active growing seasons.
A soil test is the best starting point. It can identify nutrient deficiencies and help prevent unnecessary treatments.
7. Assuming Every Brown Area Needs More Water
Brown or thinning grass does not always indicate drought.
Several problems can create similar symptoms, including:
- Brown patch and other fungal diseases
- Uneven sprinkler coverage
- Mower damage
- Compacted soil
- Insect activity
- Fertilizer burn
- Pet urine
- Heat stress or summer dormancy
Adding more water without identifying the cause can make certain problems worse. For example, excessive moisture may contribute to fungal disease.
Brown patch commonly affects tall fescue during warm and humid weather. Meanwhile, insects and summer weeds can also become concerns during the growing season.
Before treating a damaged area, examine the shape and location of the discoloration. Also, check the soil moisture and sprinkler coverage.
A correct diagnosis can prevent wasted treatments and further lawn damage.
Better Summer Lawn Care Starts With Consistency
Summer lawn care does not require treating the lawn every day. However, it does require careful observation and consistent maintenance.
Mow at the proper height. Follow the one-third rule. Water deeply when the lawn shows signs of stress. Also, avoid applying fertilizer or pesticides without understanding what the lawn needs.
Most importantly, adjust your routine based on the grass type and current weather. A tall fescue lawn will not respond to summer in the same way as Bermuda or zoysia.
