Lawn Turns Yellow In Winter: What Is The Reason?

Lawn Turns Yellow In Winter: What Is The Reason?

In the cold season, the lawn has winter rest. It is not fertilized, watered or even cut. In winter, the grass does not grow, so maintenance is unnecessary. Nevertheless, the lawn can change in winter, for example, it can develop yellow spots. This is especially noticeable when it is not under a thick blanket of snow.


There are two main causes when the lawn turns yellow in places in winter. One is too much fertilization and the other is waterlogging, which damages the roots of the grasses. The dying grass then turns yellow. Too many nutrients or incorrect fertilization in the fall make the grass susceptible to frost damage, also then it dies.

Other causes Can be:

  • too little air under snow or leaves, the grass suffocates
  • compacted soil, favors waterlogging
  • fungal or other lawn diseases


The most important measure is good care of the lawn during its growth phase. This includes regular mowing, fertilizing as needed and sufficient watering. In this way, a robust, green lawn will develop that can survive the winter without damage and will not turn yellow.

Patience is necessary

When yellow spots appear in the lawn, it should not tempt you to want to take immediate action. Despite the spots, you should always remember that the lawn is in winter dormancy and most measures then do more harm than good. This is especially true for watering or fertilizing. The grasses do not absorb water or nutrients, instead watering leads to waterlogging which exacerbates the problem.
If insufficient air circulation is responsible for the yellow spots, it already helps if the lawn is cleaned of all other things, especially leaves and other plant debris.

“Note: If the lawn has received autumn fertilization, it is impossible that it will suffer from a lack of nutrients in the winter

After the winter dormancy.
Really treat the lawn only when it starts to grow again, that is, depending on the weather and location, in late March, early April.

Attention: in case of persistent wetness, do not walk on the lawn, it will only further compact the soil.

Thoroughly clean the entire area. Remove all plant debris, tree branches, and any debris that may have flown up.When soil is reasonably dry, scarify lawn to increase aeration.

Resume lawn care. However, wait to cut until the grass is strong enough and has gained about 10 inches in length.

Arrange for soil analysis and resume fertilization as needed.

Irrigate during drought conditions.

If yellow patches do not disappear on their own as a result of these measures, but bare patches develop in the lawn, these must be reseeded.


This includes proper care in the fall. Fertilizing is stopped in time before the winter dormancy. The lawn should always be fertilized very sparingly and preferably only after a soil analysis. This is the only way to ensure that exactly the nutrients that are lacking are supplied. Although nitrogen-rich fertilization ensures rapid growth, it also weakens the plants, causing them to develop soft, less resistant leaves.

Too much water also harms the grass. Especially in loamy, heavy and compacted soils. It is then better to water less, but thoroughly, to encourage the grass plants to grow longer roots.

You can prevent the lawn from turning yellow by removing falling leaves in the fall. Do not mow the lawn too late or too short and do not leave the cuttings lying around.

In the case of compacted soils, additional scarifying can be useful. This breaks up the soil, aerates it better and protects it from waterlogging. Afterwards, however, the area should no longer be walked on, or as little as possible.

If snow falls on a lawn, it does not necessarily have to be cleared. It protects the grass from temperatures that are too low. However, when shoveling snow, avoid bringing more snow onto the lawn.

Note: Thaw water that forms due to possible snow melt should be able to drain well
