why does my lawn have yellow spots

During the summer, many of us have unattractive yellow lawns. This is due to our conservation efforts with regard to water. Water rates go up in summer and much of the country is in drought conditions, so suspending water to the lawn makes sense. There are also other issues that can cause a lawn to discolor. Among these are dog urine, pests, disease, overuse, and fertilizer amounts. But do you know how to turn a yellow lawn green again? Read on for some fixes for yellow lawns. Yellow lawn problems could stem from a host of conditions. The most common is dryness but excess nitrogen is another. This is most frequently from
but can also come from. is the first number in a. It enhances green, leafy growth and is a necessary nutrient for a healthy lawn. However, too much nitrogen can cause a lawn to yellow. This is because it burns roots and changes the of the soil. This creates issues with the rootsв ability to uptake other nutrients and water. Always deeply. Similarly, dog urine has high nitrogen content and burns spots in the lawns. These are easily recognized as yellow spots bordered by greener grass. This is because the diluted edges of the urine area are actually feeding the grass, but the concentrated center is burning the roots. Train Fido to go in another area of the garden. Another potential cause is heat and sunlight.

Excessively hot weather and areas that are exposed to full sun all day will dry out quickly, and the heat stresses the lawn. This results in yellow areas. and deeply will usually correct the issue. Yellow Lawn Diseases, Pests and Deficiencies If you donвt have a dog and you water frequently, you may have to get down on your hands and knees to find the culprit. Small larvae or insects could be chomping on grass roots and affecting the color or there may be a disease. Look for patterns when determining if you have any yellow lawn diseases. Faded, yellow turf grass can also stem from disease or deficiency. or will cause the green to fade. A can indicate if there are any deficiency areas and then you can correct them with a plant food. Combat with a good applied in spring and with good cultural yellow lawn care. This includes regular watering, and, and giving the lawn food in early spring and again in early summer. If you still canвt find the issue, get out a magnifying glass and lay down in the grass. Part the blades and look in the thatch for larvae and insects. Any number of insect larvae may be eating the roots of the grass. Adult insects are not usually the problem so you need to get to the larvae when they are young. Once you have identified the culprit, use an insecticide formulated for that pest.

After you have figured out why your lawn is faded, it is time to figure out how to turn a yellow lawn green again. The easiest way is to give the lawn good care and enhance the vigor and health of the turf grass so it has the strength to combat any pest or disease problems. so plenty of sunlight can get into the area. Maintain a sharp mower and only mow when the grass is dry. and aerate to increase air circulation to roots. Rake up excess grass clippings which can make a home for pests and harbor disease. The same goes for fallen leaves. Another very important aspect of yellow lawn care is to water deeply, but infrequently, in the morning when leaf blades will have time to dry. Fertilize as recommended and watch for weed competitors which can suck resources from the lawn. Before proceeding with any type of action, make sure the grass is not turning yellow or brown because it's going dormant. Dormancy is a natural reaction in turfgrasses, prompted by seasonal temperature changes. Cool-season grasses go dormant in the heat of summer, warm-season grasses in winter. Dormancy is a resting period, do not fertilize during dormancy. Nitrogen Deficiency To look and feel their best, all types of turfgrass need to be fertilized. Lawns that are not getting enough nitrogen (the key component of lawn fertilizer) will begin to change to light green and then yellow.

The color change usually begins to show first in the lower leaves. Reduced growth is also a sign of nitrogen deficiency. Normally the entire lawn is affected. Adding nitrogen will help restore the green color if the fertilization is done properly. Applying too much at the wrong time can do more harm than good. Grass cycling adds nitrogen naturally to the lawn. Our turfgrass care tips gives you the right lawn care plan for your grass type. Iron Deficiency Another reason for discoloration could be lack of iron in your soil. Some of the more common areas of the yard that might find themselves turning yellow are those adjacent to things made of concrete. Driveways, sidewalks and concrete planters can be the culprits. The high alkaline content in concrete tends to absorb the iron found in soil, reducing the amount of iron your lawn or garden receives. Iron deficiency appears in patches. Blades may yellow but the veins retain their green color. Growth may not be affected. Alkaline soils (such as in the midwestern and western states) are especially susceptible to iron deficiencies. Iron is a natural soil supplement that neutralizes alkalinity and helps replenish the iron that occurs naturally in the soil.

Apply as directed on the package. Remove the product from masonry or concrete surfaces before watering to avoid staining. Lawn Disease or Insects Yellowing grass is also a symptom of several lawn diseases. Should there be evidence of disease or insect pests, get a positive identification of the problem before trying to treat it. Your local Cooperative Extension Service can help. Physical Damage Yellow or brown spots may be the result of a simpler problem. Gasoline spills, over-application of pesticides, foot traffic, scalping the lawn when cutting or mowing with a dull blade can all cause discoloration. Affected areas need to be repaired and reseeded. Pets The high nitrogen content of dog urine can be especially detrimental to lawn grasses. For yellowing turfgrass due to pet urine, the best treatment is to flush the area with water (as soon as possible - within the hour is best). If you think you can train your pet to "go" elsewhere in the lawn, it's worth a try. You may also want to check with your veterinarian about dietary supplements made to reduce the pH and extra nitrogen in dog urine. A soil test will determine what, if any, soil amendments are necessary to improve the soil. Maintaining the proper pH for your specific turfgrass keeps it green and growing.
