Causes of Lawn Death Why does Lawn die suddenly

1. The moisture is not timely after the lawn is planted

After the summer lawn is planted, watering is the key to survival, and the lack of water is one of the important reasons for the yellowing and death of the new lawn. In the case of high temperature, the upper transpiration is large, if the roots lack water for two hours, there will be retraction and wilting, and the lawn that dies due to lack of water will be difficult to treat in the later stage, so after the lawn is planted, sufficient water ** is essential.

Watering precautions: the newly paved lawn must be watered thoroughly when watering, because there is a gap around each lawn, and it is easy to water through all around, and ignore the middle area, you can choose a few lawns from the middle of the newly paved lawn in the early morning of the next day after the watering is completed, and turn them over to check whether the middle part of the lawn is watered thoroughly.

2. The grass roll was shelved and not planted in time

If the summer lawn is left for a long time after rolling, the inside of the rolled lawn is not ventilated and easy to heat.

Causes root burning, and burns after lawn planting.

The roots cannot be recovered, showing weak growth, slow roots, or no roots, and finally the entire lawn dies.

In the high temperature season, reducing the shelving time of the grass roll, planting as soon as possible, and watering in time can effectively avoid the lawn drying and dying.

3. The newly laid lawn is not fully bonded to the soil

The lawn is not stepped on after being paved, causing the lawn to hang in the air, and the turfgrass root system can not absorb water from the soil well, causing the lawn to wither and die.

4. Disease causes the death of newly laid lawns

In summer, the high temperature and humidity make the lawn prone to brown spot disease.

and diseases such as Pythium wilt. After planting, if the water is not enough, the lawn has few roots, the growth is weak, and the weak lawn dies directly after the invasion of brown spot disease; However, if the humidity is too high, the drainage is poor, and the soil is alkaline, Pythium wilt is easy to occur in a large area, resulting in root rot, stem rot and leaf rot of turfgrass.

It is extremely destructive and can cause the death of a series of turf patches.

Sickness or weather, too heat, not enough water, resulting in too much drought.

It should be watering too much and the cells are swollen and dead.

Lawn diseases, lack of water, lack of fertilizer, lack of light, poor drainage leading to stagnant water, excessive mowing, etc.

Whether it is a lack of water, fertilizer, sunlight, or a pH test paper to measure the pH. See if the underground pH is abnormal.

Excessive pruning will prevent the aboveground part from providing enough assimilation products for the root system, hindering the growth of the root system, and the lawn will die due to nutrient deficiency.

When the lawn grows high enough, the lower leaves are shaded for a long time, unable to see sunlight, and have adapted to the shade environment, when the upper leaves are cut off, the lower leaves are exposed to the sun, which can cause leaf burns due to excessive light.

Lawn Mowing Principles:The principle of 1 3 should be mastered when mowing the lawn, the tall lawn can not be cut to the required height at one time, each time pruning, cut off 1 3 leaves, so that the retained leaves can carry out photosynthesis normally, for the root system to supplement the assimilation products.

It is possible that the mowing is too low, the lawn leaves are all cut off, and the nutrients cannot keep up with the death.

Maybe you haven't mowed for a long time and suddenly build too much, the general rule of lawn mowing is not to mow more than one-third of the total height of the lawn at a time.

Most lawn diseases belong to fungi, such as rust, powdery mildew, anthracnose, etc., which can make the lawn yellow or die. Prevention and control drugs commonly use methyl tobuzin, carbendazim, chlorothalonil, etc. The pests that harm the lawn are armyworms, ants, mole crickets, etc., and the commonly used insecticides are insecticidal double, inulin-killing, trichlorfon, etc.

Watering after mowing can easily infect the lawn with diseases.

I don't understand.

1. Drought, too dry soil will cause turfgrass not to grow yellow, and even cause death.

2. Waterlogging, in the summer of high temperature and rain, some low-lying lawns are easy to accumulate water, resulting in yellowing of the lawn and not long, and death in serious cases.
