With warmer weather around the corner, many homeowners are preparing their lawns for spring. While the ultimate goal is lush, green grass, the last thing any homeowner wants is a yellow lawn. So what is causing those offensive spots and how can you fix them? Here we take a look at the 4 top reasons for a yellow lawn and how to fix it.
Physical damage to your grass can come in many forms. Cutting your grass unevenly, too short, or with dull blades on your mower can result in it turning yellow as the grass is weakened and destroyed. If you have items sitting on your lawn (such as children’s play equipment or lawn furniture), you will often see yellow spots pop up around them as a result of soil compaction. In this case, oxygen and water are unable to reach the roots of the blades in order to circulate.
When mowing your grass, make sure the mower is working properly and the blades are sharpened. Set the blades at the proper height for the type of grass you have. Aeration can help resolve the issue of soil compaction and allows your grass to get the oxygen, water and other nutrients it needs to thrive.
Amount of Water
Too much or too little water can wreak havoc on your lawn, resulting in those unsightly yellow patches you’re trying to avoid. Overwatering leads to poor root development and a limited supply of oxygen. It can also lead to fungus and pest infestations. Underwatering can dry out the blades, making them brittle and undernourished, which can also cause them to turn yellow.
Double check your sprinkler system to make sure they aren’t overwatering certain areas of your lawn and that they are reaching all of the areas of your lawn. Keep an eye on the weather to make sure your lawn is getting just the right amount of water (e.g. turning off sprinklers during rainstorms). Identify what type of grass you have and make sure your watering schedule is appropriate.
Lack of Nutrients
Fertilization provides the nutrients your lawn needs to grow and thrive. Yellow patches can appear when your lawn lacks the proper amounts of these nutrients. On the other hand, overfertilizing can burn the turf, also causing the grass to turn yellow. It is important to find the proper balance of nutrients necessary for the type of grass you have.
Choose a fertilizer that is appropriate for your turf type. Make sure to read the directions carefully and apply evenly across your yard. A nutritional supplement may also need to be added in addition to the fertilizer to help replenish your lawn.
Diseases and Pests
Many lawn diseases manifest as yellow or even brown patches. Some of the most common diseases include lawn fungus and dollar spot. Most lawn diseases are fungal and are caused by excessive moisture. These diseases slow the growth of your lawn and can cause the blades to spot and wilt. This excessive moisture is also a major attractant for pests which can also damage your grass and cause it to turn colors.
The first step is to get rid of the excess moisture in your yard. A fungicide may need to be applied depending on the severity of the disease. Lawn diseases should be treated as soon as you start to see symptoms. Try to avoid overwatering the areas and follow good mowing habits, as well. The damaged areas can sometimes be repaired by raking away the thatch and reseeding in the fall.
