Fescue will stop growing when dormancy occurs. The seedlings and mature grass, yellow because the cold temperatures stopped the photosynthesis process causing the yellowing. It can also be caused from frost damage. When the weather warms up the turf should recover. Organic fertilizers hardly burn grass and are less likely to cause yellowing.
Applying one will turn a yellowing turf green within weeks. Caution : Excess nitrogen can burn the roots and change the pH of the soil. Iron chlorosis occurs in lawns that have a poor soil pH, so correcting this is the first step to fixing the yellow grass. After amending the soil pH, apply an iron rich fertilizer such as Milorganite especially if the yellowing was not caused by overfertilization.
If your lawn is well fed yet it is showing signs of iron deficiency, apply an iron supplement for lawns such as Ironite. Dog urine contains high concentrations of nitrogen that burns the grass when your dog pees. To fix yellow patches caused by dog urine, do the following:.
Following your dog in the yard and training him can be a tough task but it will save your lawn from yellowing. Train your dog to only use a specific part of the garden, preferably where you do not have grass. Sometimes, dog urine spots do not re-grow, particularly when you take long before applying a dog urine neutralizer.
Pests such as chinch bugs and grubs can cause damage to your lawn that will manifest as leaf discoloration and even dead brown patches of grass. Fungal infections are also known to cause yellowing and greying of grass blades at the base of the shoots. To turn yellow grass green fast, apply a lawn fungicide such as Scotts DiseaseX.
It will get rid of most fungal infections that cause leaf discoloration and root rot. For pests, apply a grub killer in early spring to prevent the larvae from feeding on the roots of your turfgrass and causing it to turn yellow-brown. Water the lawn deeply every week. Irrigate early in the morning to give the water time to dry during the day and prevent fungus. The type of soil also will determine how fast the water drains away.
For example, grass growing in sandy soil needs more watering. To break the compact soil, you can use lawn aerators. They range from shoes with spikes for smaller lawns, to larger gas-powered lawn aerators for larger yards. They are also designed to make holes in the soil to facilitate water infiltration.
However, be wary not to water your lawn too often, as it will get waterlogged and lead to a muddy yard. Probably, once or twice a week will be enough when it is hot, but only water your garden when necessary.
New grass can turn yellow depending on factors like where you live, type of grass, and soil type. Newly germinated grass can start to lose color and look unhealthy if proper care and maintenance is not provided. A new turf established in a shaded area can quickly appear to suffer from malnutrition because of lack of adequate sunlight.
The new shoots start to elongate abnormally fast to reach for the sun. The result is a pale-yellow coloration of the grass blades. Yellow grass is not a definite sign it is dying. Grass can grow back and thrive if the underlying cause such as overwatering, underwatering, or fertilizer burn is fixed.
To help yellow grass bounce back quickly from drought, water the lawn deeply as soon as possible to revive the dying grass. Wilting and dying turfgrass from fertilizer burn can also die quickly if the excess nitrogen salts are not flushed out of the soil soon enough. Similarly, pests and diseases can kill grass if not treated early enough.
The reason why lawns turn yellow during winter is dormancy. Grass varieties that cant tolerate the cold temperatures during winter go into dormancy and come back to life during the warmer seasons starting spring. Besides dormancy, winter also brings about rust and snow mold, which are fungal diseases.
Also, since people use salt to clear drive ways and roads, the salt builds up in the soil, making it toxic for the grass. Warm-seasoned grasses cannot tolerate the cold, so they naturally turn yellow while the cold-seasoned grass can endure the winter. To prevent lawn rust, fertilize the lawn often, water and mow it as required. You can use alternatives such as sand or pets litter to prevent the salt from building up in the soil.
Summer brings about high temperatures which cause heat stress. This leads to tough soil, wilting of grass, soil compacting, and discoloration of grass. As mentioned earlier, lawn diseases, pests, and dog urine could also cause the grass to turn yellow during this season. Remember the kind of grass seed planted makes a difference as well as the type of soil in your lawn. Your lawn can get excess nitrogen from two sources: overfertilizing and dog urine.
Nitrogen is a chemical that enhances green leafy growth and is a necessary nutrient for a lush, healthy lawn. Too much nitrogen, however, can cause chemical burns to grass roots and a change in the pH of soil, leading to yellowing grass. Dog urine also contains a high concentration of nitrogen and can cause burn spots on your lawn.
Urine spots are often yellow bordered by greener grass because the diluted edges of the urine actually feed the grass like fertilizer while the more concentrated center of the urine spot burns the roots and causes the discoloration. The best way to minimize damage from excess nitrogen is to prevent it in the first place. Use caution when fertilizing and make sure to water it in deeply when applied. If damage has already occurred, water the patch immediately to drain it and then water everyday for a week.
Put in compost to replenish any lost minerals. If the grass is already dead, put sod over the area and reseed it the following season. Train your pet to urinate in other places and not go to the same spot repeatedly. Water any urine off your lawn immediately to minimize damage. Most turf diseases that cause your lawn to have yellow spots are fungal. Some of the most common fungal diseases include fairy rings, snow mold, fusarium, and smut. To help prevent fungal disease, make sure your lawn is dethatched and aerated.
Try to water in the early morning hours so the moisture has time to evaporate throughout the day and not sit overnight. Make sure to also rake up any clippings, debris, and leaves to prevent moisture from being trapped underneath.
Nutritional deficiencies can lead to discoloration of your lawn.
