Identifying the Cause of Yellow Grass
There are several reasons why your grass may turn yellow. Here, we will discuss the different causes of yellow grass and how to identify them.
One reason why your lawn may turn yellow is due to lack of water. When soil dries out, it affects the roots of the grass which can’t absorb nutrients. This ultimately leads to the grass turning yellow and dry. Water plays a crucial role in keeping your lawn healthy and green. If you live in an area prone to drought, it’s essential to water regularly.
The second reason why your lawn might be yellow is due to over-fertilization or misapplication of fertilizer. While fertilizers can be good for your lawn, overdoing it can do more harm than good. Excess fertilization can cause burnout and yellowing of the grass. It’s essential to use the right type of fertilizer for your lawn and to apply it in the recommended amount and frequency.
Another reason why your lawn might be yellow is due to disease. Fungal and bacterial diseases can turn your grass yellow and cause it to die. Symptoms of lawn disease include circular brown or yellow spots on your lawn. Other factors that contribute to lawn disease include poor drainage, overwatering, and high humidity. If you suspect that your lawn has a disease, it’s important to get professional help to diagnose and treat the problem.
One of the lesser-known reasons for yellow grass is due to pests. Insects such as chinch bugs, ants, and grubs can damage the roots of the grass, causing it to turn yellow. Signs of pest infestation include brown patches and chewed grass blades. It’s crucial to address any pest problems as soon as possible to prevent further damage to your lawn and eradicate the insects.
Lastly, it’s essential to assess the type of grass on your lawn. Some types of grass are more susceptible to yellowing than others. Warm-season grasses like Bermuda and Zoysia tend to turn yellow during colder months, while cool-season grasses like Kentucky Bluegrass or Ryegrass tend to turn yellow during the summer when it’s hot and dry. Understanding the type of grass on your lawn can help you address the issue and take effective measures to prevent yellowing.
Identifying the cause of yellow grass is crucial to fixing the problem effectively. Once you’ve identified the cause of the problem, you can take the appropriate steps to address it and restore your lawn to its green and healthy state.
Addressing Common Pest Issues in Yellow Grass
Have you noticed that your grass has turned yellow? One of the most common reasons for yellow grass is due to pests. It can be frustrating to dedicate so much time and effort to maintain a lush, green lawn just to have it ruined by pests. Here are some common pest issues that may be causing your yellow grass and how to address them:
Grubs are beetle larvae that feed on grassroots. They can cause significant damage to your lawn if they are not treated early. You can identify grubs by digging a small patch of your lawn and looking for white or grayish “C” shaped larvae. You can also spot damage by noticing brown patches of grass that can be easily pulled up because they have no roots. To address grub issues, use a grub killer or insecticide. These products should be applied before the grubs have turned into beetles.
2. Chinch Bugs
Chinch bugs feed on the sap in grass blades, which can cause the grass to brown and die. They leave behind a characteristic yellow striping, which can help you identify them. To address chinch bug issues, use a pesticide designed for these insects. You can also create a barrier by mowing your lawn regularly to prevent chinch bugs from infesting.
3. Sod Webworms
Sod webworms are the larvae of moths that live in the thatch layer of your lawn. They feed on the stems of grass blades, which can cause them to turn yellow and die. You can identify sod webworms by noticing small, light brown tubes that they create out of thatch and silk. You can address sod webworm issues by using an insecticide designed for sod webworms. You can also remove thatch by raking your lawn during the fall to reduce the likelihood of infestation.
Ants are not always damaging to grass, but they can create unsightly mounds that can cause damage to lawn mowers and cause browning around the area. Large colonies can cause grass to turn yellow and die. You can address ant issues by using ant baits or insecticides. You can also remove their habitat by mowing the lawn regularly, keeping the area dry, and reducing your lawn’s thatch layer. Avoid using pesticides that also kill beneficial insects, like bees.
It is essential to identify the specific pest that is causing damage to your lawn, and it may take a bit of research and some trial and error to get the right solution. However, with the right effort and care, you can address common pest issues in yellow grass and achieve a lush, green lawn once again.
Reseeding and Resodding Yellow Grass Areas
If you have a lawn with yellow patches, then reseeding or resodding is the best way to get it back to its former green self. Reseeding your lawn means re-planting grass seeds in the yellow patches. This process takes about a week to see the first level of growth and up to 2 months to completely see the new grass integrate with the old. With good watering and feeding practices, your lawn can soon become healthy again.
If the grass in the yellow area is too dead for reseeding to work, then resodding it is the better option. Resodding your lawn is a bit more expensive than reseeding, but it is also faster. You can do it within a day and have your lawn looking good as new. In resodding, all the old grass and soil in the yellow patches are removed and replaced with new sod. The new sod is installed with precision and care, ensuring that the edges fit perfectly into place. After installation, the grass must be regularly watered for four weeks, as it will require time to establish itself. Within six to eight weeks, the new grass will become fully rooted in the ground.
Reseeding Yellow Grass Areas
Reseeding your yellow patches is a great option if you want to rejuvenate your lawn without incurring too much cost. However, for reseeding to work, you need a suitable growing environment for the new grass. Before planting, remove any dead grass and weeds from the affected area, and loosen the soil. You can use a rake or tiller to accomplish this task. The surface must also be firm so that the new seeds have an ideal base. Afterward, add some new soil, and spread the seeds over the yellow patches. Using gentle water, water the seeds regularly so that they remain moist and germinate well. To ensure that the new grass grows healthy and vigorously, remove any weeds that appear in the lawn and also provide nutrients with modern fertilizers.
Resodding Yellow Grass Areas
If you decide to go with resodding, then you need to prepare your yard for the new sod. Remove any dead grass and weeds, and make sure that the dirt is free from any big rocks. In leveling the surface, use a rake or tiller, and ensure the surface is flat. Afterward, add topsoil and fertilizers, and level the surface again. It is also essential to provide ample moisture for the new grass to thrive. Before adding the new sod, it’s crucial to measure the depth of the soil and calculate how much sod you’ll need. The new sod should neatly fit the area, with no overhanging edges. After installation, water the new grass for about four weeks, ensuring the surface remains moist. Overwatering the grass may lead to fungal diseases setting in, which you want to avoid.
The Bottom Line
Reseeding and Resodding yellow grass areas is an excellent way of rejuvenating and bringing back your lawn to life. The choice will be based on whether your grass is still viable. Reseeding is the most common practice, but it requires additional care for the freshly planted seed. On the other hand, resodding is a quicker option and does not involve many steps than reseeding. The result is the same with both options: a healthy, green lawn that you can enjoy for years to come.
