Yellow spots in the lawn

Yellow spots from urine

dogsthat have access to a green space and some wildlife are a common cause of circular yellow spots. Urine and feces contain various substances that are corrosive. Since dogs like to do their business in the same place, large amounts of pollutants accumulate there.

The most important thing is to dilute the urine. Pour ten to twenty liters of water on the affected area, preferably immediately after the dog has loosened there. This measure must be taken at the latest when the first slight discoloration appears.

Fence that race or spray deterrents to discourage animals from using the green as a toilet. The grass will not recover if it is severely discolored. Scrape away the diseased grass and sow new gas.

Incorrect mowing can damage the lawn

Two mistakes lead to lawn stains: Leaving a cutting height of less than three centimeters or stalks that are longer than four centimeters on the lawn. Too low a cut is dangerous in the heat, the grass will burn in the sun. Long stalks that remain on the lawn after mowing suffocate the grass underneath.

Mow the grass when it is eight centimeters long to a height of four centimeters. Leave the clippings on the surface for mulching.

Use fertilizer properly

Research has shown that most lawns are over-fertilized. Many gardeners fertilize their lawn several times a year without doing a soil analysis. If the green shows spots, try to combat them often with fertilization measures. This exacerbates the problem.

Take a soil sample from the lawn and have it examined by a specialist retailer. Follow the recommendations that you will receive after the analysis.

Get through the summer without heat damage

Lawns need regular water. Many gardeners go completely wrong when it comes to watering. It is of no use to the grass if you give it a small amount of water every day. The water does not get to the roots. The lawn dies of thirst even though you water it regularly.

If the lawn is not damp in the early morning and is bluish in color, it is time to water. Long and even sprinkling is important so that the soil is moisturized. Soak the lawn for three to four hours in the evening. The water seeps into the ground at night instead of evaporating.

One square meter of lawn needs between 15 and 20 liters so that enough water can get to the roots. Set up a rain gauge to check the amount of water.

Bad soil damages the grass

If you don't make any mistakes when mowing, fertilizing and watering and the lawn still shows yellow spots, it is often due to the soil quality. Mosses in the grass are a clear sign of compacted soil. If the ground seems hard as stone, it is time to aerate. Aeration means making holes in the lawn to loosen it up.

You need a corresponding device from a specialist retailer. Ask about a scarifier and aerator to rent. Scarifying First to cut open the root felt. When you ventilate the room afterwards, you will make small holes in the floor. Scatter sand that loosens the soil.

Chemicals as the cause 

If your lawn has brown or yellow spots in some places and is otherwise lush green, chemical substances are usually the cause. Think about gasoline or oil from the mowing machine leaks or whether you spilled something while filling the tanks. Maybe you are fertilizer fallen next to the fertilizer wagon?

Dig up the affected area and dispose of the soil with household waste. Put new garden soil in the hole and sow new lawn in the area.
