10 Main Lawn Diseases and Problems

1. The bald spots

The cause of the appearance of patchwork on a young ornamental lawn is often explained by the poor germination of poor-quality seed material.
But there are a number of other reasons for the formation of proletrics:

  • Insufficient thorough preparation of the site.
  • In particular, if the soil has been badly dug up, with the subsoil turning upward, in some places the fertile layer may simply be absent, which means that the seeds in these areas are doomed to death due to a lack of nutrients.


  • Extreme weather conditions, such as drought or prolonged rains, can suppress the development of seeds, and the shoots will be thin.
  • Unprotected crops can be hunted by birds;
  • Seeds, partially lost their germination due to long-term storage.
  • Uneven shoots due to poor drainage of the site. Rot, developed from excessive moisture, kills the seed material even before they begin to germinate. To reduce the harmful effect of rot, it is recommended to treat the seeds with a fungicide before sowing.

2. Spots of yellowed or dead grass (brown patches)

Great trouble threatens the decorative lawn because of the so-called black leg, when the stems of young grass grow black at the base and fall. The grass turns yellow and effortlessly pulled out of the ground. Usually, a black leg develops in wet weather in thickened crops, most often the disease affects the field. The disease quickly captures the entire English lawn, so measures must be taken immediately to save it. Once you have found the infection, treat it with a foundation.

The herbal cover can turn yellow not only from infection. If the grass has not fallen down, then the following reasons are possible:

Improper preparation of the site before sowing. The most common mistake & ndash; Left infertile soil. Unharvested bricks and construction debris can also become one of the reasons for the formation of yellow spots on the surface of the lawn.

Drying or vice versa, wetting of the lawn surface, as a result of prolonged drought or heavy rainfall, respectively

3. Rare weak sprouts

It happens that the shoots are dense, and the grass grows well, but the grass cover turns out to be a rare, bald, with a translucent earth between the grass. Perhaps the following happened:

Incorrect calculation of optimal seed consumption for lawn sowing. On each package with seeds there is an instruction, if it is not available, or you purchased seeds by weight, then the approximate expenditure for sowing 10 sq feet Meter area of 1-1.2 ounce of seeds.

It is unlikely, but the cause of sprouting can be birds. Usually birds hatch crops unevenly, hence the bald spots.

Like many other problems of a young lawn, a loose grass can be formed due to poor preliminary preparation of the site. Poor drainage, the formation of the upper layer from the subsoil instead of fertile land. Try to feed the sown lawn, but, unfortunately, this cause can not be completely eliminated.

4. Pale color and cessation of growth of young grass

If the young lawn grass loses its color, then you must feed the lawn.

It happens that the young grass loses color and practically does not grow. Perhaps the emergence of this problem is associated with a lack of nutrients in the soil, especially in the spring. Feed the decorative lawn with growth stimulators containing nitrogen. In order not to oppress the vitality of a young lawn, refrain from the use of general herbicides, as well as complex fertilizers, which include herbicides. It is best to feed the grass with a liquid nitrogen fertilizer with a very low concentration. Try not to overload the young lawn, let the grass grow stronger.

5. Formation of cracks on the surface of the sown lawn

With irregular and sparse watering, the surface of the young landscape lawn crackles. Quite often this problem occurs in areas with heavy soil. To eliminate cracks, the lawn needs to water abundantly and cover up the damaged area by adding a few grass seeds to the mulch. If, after the restoration of the surface of the lawn, dry weather has set, then regularly water it to prevent the formation of new cracks.

6. Formation of cracks on a laid lawn.

The problem is shrinkage of the turf. In this case, the plates diverge and ugly crevices appear between them. As a rule, sods sit down from a lack of moisture during irregular or weak watering during the dry period. If the plates were not laid tightly, and the joints were not sealed with mulch, the shrinkage of the turf with bad watering occurs more quickly, and the resulting cracks become even more ugly. Eliminate this defect by intensive turf irrigation. Then, when the surface of the decorative lawn is saturated with moisture, and the sod becomes the original size, fill the gap between them with a mixture of garden soil and sand.

7. Formation of depression on the lawn

The lawn grate helps to strengthen the lawn, broken on the slope.

Poor preliminary preparation of the site, namely incorrectly compacted soil, leads to the formation of depressions on the surface of a young lawn due to shrinkage of the earth. On a sown lawn, the formation of depressions is facilitated by birds that like to swim in the dust. If the decorative lawn is broken on the slope, then there is a possibility that the depressions formed as a result of erosion of the soil after heavy rains. You can even out the relief by covering the depressions of mulch. And to strengthen the lawn on the slope, use the lawn grate.

8. Weed plants

If before planting a lawn you thoroughly cleared the site of weeds, then later you will not need to take drastic measures to combat them. Naturally, weeds will from time to time appear on a landscape lawn, but not in such horrendous quantities. In addition, most weeds do not withstand regular haircuts and die. However, there are kinds of weeds that are not afraid of haircuts and perfectly develop on the lawn, spoiling its appearance. Such uninvited guests should be weeded out manually, and do this without waiting for them to grow up.

If, because of excessive haste, you missed the important technological stages of preparing the site for sowing or laying turf, then the weeds on the lawn could grow so much that you can not cope with them manually. In this case, you will have to arm yourself with chemicals, but remember that herbicides can be used on a young seeded lawn, not earlier than a year after sowing seeds and 6 months after laying the turf.

9. Stones

Stones have the property of coming out of the earth to the surface. Therefore, before each haircut, carefully inspect the garden lawn in order not to break the lawn mower.

10. Restoration of a young lawn

It is necessary to restore the decorativeness of the grass cover very carefully. Areas on which formed bald spots or places with sparse shoots gently loosen the rake, so as not to damage the flat surface of the lawn. Then, mix 1 part of the seeds with 10 parts of the soil mixture consisting of garden soil and sand. The resulting mulch fill up the problem areas and slightly rake the rakes.
