Why Is My Lawn Turning Yellow?

If you’re wondering “Why is my lawn turning yellow?”, don’t worry. We’ve got some answers. While there are more than 11,000 grass species out there, there are only a handful of reasons why you would be dealing with a yellow lawn.

Find out what could be causing grass turning yellow from natural occurrences like lawn dormancy to more serious lawn diseases such as snow mold or fusarium.

Lawn Diseases

Disease is a common reason for grass turning yellow and the most common lawn disease in this instance is fungal. Fungal diseases include dollar spot, fairy rings, fusarium, snow mold, and smut. If disease is the reason your lawn is yellowing, it’s essential to get control of its moisture levels and make sure your lawn is well aerated.


Too much water in your lawn can lead to a limited supply of oxygen in the soil thanks to waterlogging. This causes your grass to then develop shallow roots and eventually suffer from an inability to uptake oxygen, nutrients, and water. This is when your grass starts to turn yellow.

Watering your lawn too much can also lead to insect infestation and fungal diseases because of its reduced resistance to attacks.


If you’re still wondering, “why is my lawn yellow?” another reason could be overfertilization. Too much fertilizer can actually burn your lawn and this is particularly true when it comes to synthetic fertilizers. This reason could be an easy one to spot as you will likely see your grass turning yellow soon after applying the fertilizer.

Nutrient Deficiency

From too much fertilizer to too little, your lawn may also be yellowing because of a nutrient deficiency. When there are spots in the lawn that have missed out on fertilizer, you’ll be able to notice a fluorescent or yellow discoloration on the leaf blades while the rest of the lawn could be deep green. To help get the balance under control, it could be best to call in a professional like  https://whenappearancematters.com/service-area/baton-rouge/.

Lawn Dormancy

Lawn dormancy occurs when your grass goes to sleep to protect itself from upcoming harsh weather conditions. This usually happens during particularly cold or dry seasons. Similar to a cactus, this is your lawn’s way of conserving what little water it has to keep its roots alive.

Dog Urine Spots

Another reason for a yellow lawn that might be right under your nose, is dog urine. If you have dogs that tend to pee in the same area, you may start to find yellow patches around your lawn. This is because dog urine contains high nitrogen compounds.
