Most Common Fall Threats to Florida Lawns

As the summer heat begins to subside, and the days grow shorter, fall arrives in Florida, bringing a welcome relief from scorching temperatures. While fall may not bring the colorful foliage seen in other parts of the country, it does bring its own set of challenges to Florida lawns. Here are the most common fall threats to Florida lawns to look out for, so you can maintain a vibrant and healthy lawn through the autumn months.

Fungal Diseases

With the increase in humidity and occasional rainfall during the fall season, fungal diseases become a significant threat to Florida lawns. Diseases like brown patch and dollar spot can quickly take hold, leaving unsightly brown patches on your grass. To prevent fungal diseases, avoid overwatering, improve air circulation, and use a well-balanced fertilizer.

Weeds are a year-round nuisance in Florida, but they can become particularly problematic in the fall. Weeds like crabgrass and broadleaf weeds thrive in the cooler temperatures of autumn. Regularly mow your lawn to keep weeds in check and consider applying a pre-emergent herbicide to prevent weed growth.

Chinch Bugs

Chinch bugs are notorious for damaging Florida lawns during the fall. These tiny insects feed on grass, causing yellow and brown patches. Keep an eye out for signs of chinch bug infestation, such as discolored grass and a strong, unpleasant odor. Treating your lawn with insecticides specifically designed for chinch bugs can help control their population.

Dry Spells

While fall typically brings relief from the summer rains, it can also bring dry spells. Inconsistent rainfall can lead to drought stress in your lawn. To combat this threat, ensure your lawn receives adequate water by using a sprinkler system or a soaker hose. Water deeply and infrequently to encourage deep root growth.

Thatch Buildup

Thatch is a layer of dead grass and organic matter that accumulates on the soil’s surface. Fall is a prime time for thatch buildup due to the falling leaves and increased grass clippings. A thick thatch layer can hinder water and nutrient absorption by the roots. Regular dethatching with a specialized machine or by hiring a professional lawn care service can help maintain a healthy lawn.

Leaf Accumulation

While the rest of the country enjoys the colorful display of falling leaves, Floridians must contend with the potential harm they can cause to their lawns. Leaves left on the lawn can smother the grass, block sunlight, and create a breeding ground for pests and diseases. To mitigate this threat, regularly rake or use a leaf blower to remove fallen leaves from your lawn.

Lawn Scalping

In the quest to prepare lawns for fall, some homeowners make the mistake of scalping their grass, cutting it too short. This practice can damage the grass and make it more susceptible to pests and diseases. Instead, adjust your mower blades to the appropriate height for your grass type and only remove a third of the grass blade at a time.


While it’s essential to feed your lawn, overfertilization can harm your grass. Fall is not the time for excessive fertilization, as it can stimulate new growth that may not have time to harden before winter. Follow a balanced fertilization schedule and consider soil testing to determine your lawn’s specific nutrient needs.
