The St. Louis area is finally experiencing consistent warm temperatures and with the summer right around the corner, the growth of the lawns is intensifying.  This is also the time of year when common lawn problems start to surface such as weed growth and disease.  One such disease that often appears in late spring is leaf spot which is a fungal disease that affects grass blades.  It is important for homeowners to be able to correctly identify leaf spot and take the proper actions to eliminate it.

Leaf Spot Identification

The main symptom of leaf spot is the yellow, dark-centered circles that appear in blades of grass and give the lawn an overall yellowish color.  Leaf spot typically forms in cool moist weather or on grass blades that are mowed too short.  The disease progresses into a more serious melting out stage when the weather warms up.  The melting out stage can be identified by the large, discolored turf patches that form on the lawn.  Fortunately, lawns can overcome leaf spot with the proper care and attention.

Treating Leaf Spot

If your lawn is over taken by leaf spot by the time the weather warms up, you may want to make the following changes to your lawn care regimen.  The first thing you should do is water your lawn in the morning hours.  If you water later during the day or at night, standing water may accumulate and contribute to the development of leaf spot in the lawn.  It may also help to water less frequently in lawns with leaf spot.

Another way to help eliminate leaf spot disease is by adjusting your mower blade to raise the height of the grass.  Cutting the lawn too short can contribute to the spread of leaf spot while cutting the grass blades longer will allow the lawn to better combat the disease.  Keeping the lawn free of debris and trimming overhanging tree branches will also help the lawn fight disease by improving air movement.  The most effective way to eliminate or prevent any disease including leaf spot is to regularly fertilize your lawn to help promote a strong healthy root system.

If you notice leaf spot forming in your lawn, make sure to take immediate action to eliminate the disease for a healthier, greener lawn.  Many lawn diseases can be tricky to deal with but leaf spot is a lawn disease that can be overcome with the right care and maintenance.  Make sure to contact a professional lawn care provider such as Green T Lawn Care if the leaf spot in your lawn is too much for you to handle with these tips.  The technicians of Green T can safely and effectively treat your lawn for leaf spot and many other common lawn diseases.

How to Treat Problems Hiding in Your Lawn

The spring season is fully upon us which means that it is time to kick lawn care into full gear.  Homeowners should be looking out for any potential problems in their lawns as the spring season is the time to address them.  The most common problems a lawn faces are weed growth, grubs and other pests, and diseases which are often treated with herbicides, pesticides, and fungicides respectively.  However, these problems are generally symptoms of an underlying cause that must be corrected in order to effectively eliminate the problem.  If the underlying causes are not corrected, then the symptoms will appear year after year and require another round of herbicides, pesticides, or fungicides.


Lawns are typically treated each and every year with herbicides to stop the growth of weeds but weed growth is usually a symptom of a larger problem.  By discovering the underlying cause and correcting it, you can eliminate weeds more effectively without having to apply repeated herbicide treatments to your lawn.  Crabgrass, for example, thrives in bare or weak turf patches where it can easily overtake the lawn.  Fixing the weak and bare patches with aeration and over seeding will help prevent crabgrass from thriving.  Other conditions that may encourage weed growth include nutrient content and soil pH so make sure to have the soil tested to keep the pH and nutrient level balanced.


Another common problem that lawns receive treatment for every year is grubs.  A grub infestation could result in significant damage to the lawn but insecticide treatments are administered with little attention being paid to what conditions are favorable to the survival of grubs.  Grubs tend to thrive in lawns that are well watered and well fertilized, especially late in the summer, because there is a healthy root system providing food for them.  Reducing the watering and fertilizer applications late in the summer helps prevent large grub populations from developing in the lawn.  By this point in the season, the lawn should be healthy enough from the watering and fertilization it has received to handle a moderate population of grubs without the need for grub control treatments.


Lawn diseases are another common issue that affects many lawns and certain conditions such as shade, airflow issues, and competition for water can contribute to their development.  The most effective way to reduce the development of lawn diseases is to eliminate these conditions as opposed to applying fungicides to your lawn every year.  You can reduce shaded areas by keeping trees and shrubs trimmed to allow more sunlight to reach the lawn and if an area is shaded by the house, it may be wise to plant a species of grass that grows well in shade.  Keeping trees and shrubs trimmed may also improve airflow in the lawn which can help prevent certain diseases from forming such as dollar spot and brown patch.  The competition for moisture between trees and the lawn may contribute to the formation of lawn diseases as well so it is important to balance the watering so the trees do not take water from the lawn.

Each year, lawns across the country are treated with herbicides, pesticides, or fungicides to alleviate common problems such as weeds, grubs, and diseases, but you can provide more effective lawn care by eliminating the underlying causes of these issues to avoid the repeated use of chemical treatments.  Green T Lawn Care provides services to our St. Louis customers that help correct the underlying conditions of these problems such as aeration, over seeding, and soil pH testing.  Contact Green T Lawn Care to learn more about our services and effective methods for preventing weeds, grubs, and lawn diseases.
