How to maintain the lawn throughout the year and how to maintain the lawn in June

1.Weeding and mowingFor lawns, weeds need to be removed regularly. Spring is generally the peak season for lawn growth, and it is also the season when weeds are abundant.

Weeds should be pulled out so as not to affect lawn growth. If weeds grow too much, they can rob the lawn of its moisture and nutrients, causing the lawn to stop growing, with very serious consequences. In addition, it is not okay for the lawn to grow too fast, it will affect the appearance and easily breed diseases and pests, so it is necessary to mow regularly to keep the lawn flat.

2.Loose soil lawns used for ventilation will have dense root systems that become intertwined at the beginning of flat growth, so that low-lying areas are prone to water accumulation and root rot. Moreover, if the lawn is trampled too much, the soil will become compact, affecting root respiration and drainage, so it is necessary to loosen the lawn.

A common method is to punch holes in the lawn with a hole punch to keep the soil ventilated and ventilated. The punching depth is about four centimeters, and the edge can be trimmed after punching. 3.

Fertilizer and water and fertilizer management are also important for lawns. In order to promote the growth of lawn tillering, it is necessary to apply some compound fertilizer, which can better promote the tillering of plants, improve resistance, and make the lawn grow better. In general, more fertilization should be applied during the growing season.

After fertilization, it should be watered, and there should be enough moisture during the growing period of the lawn. When the lawn turns green in the spring, there should be enough moisture for the lawn to grow quickly. Water thoroughly every time you water so that the root system can take deep roots.

Water more often in the summer.

Lawn Four Seasons Maintenance Method:

1. Spring management of the lawn

In the spring, the lawn should be trimmed early to fill in the frozen and cracked soil. When the lawn is just starting to regreen, chlorophyll can be sprayed to promote early regreening of the lawn. For the over-compacted lots, the topsoil should be filled with holes, scratches and other aeration treatments, and the finely managed lawn should be mowed when it has not completely returned to green, and when the temperature is stable above 0, it should be watered and fertilized.

For areas with serious pests and diseases, ground insect removal can be used in the soil to control underground pests (grubs, ground tigers, mole crickets, needleworms, wheat root soil, crickets, etc.), and spray aseptic control of lawn diseases. (When the lawn is planted, 10g of water-retaining agent can be applied to the topsoil at 10cm per square meter in the process of land preparation, and then watered thoroughly, which can greatly improve the early resistance of turfgrass and reduce the number of watering.) )

2. Summer management of the lawn

In summer, the trimming of cool-season turfgrass should be carried out in strict accordance with the 1 3 rule, and must not be pruned in place at one time, so as not to cause serious damage to the plant. Generally, watering should be done thoroughly at one time every time, and nitrogen fertilizer should not be applied excessively in summer, but potassium and phosphorus fertilizers should be applied at least once to improve the disease resistance and heat tolerance of the lawn. Summer is the high incidence period of lawn pests and diseases, and it is necessary to do a good job in the prevention and control of pests and diseases.

Scientific weeding of lawns with heavy weeds.

3. Autumn management of the lawn

Lawn repairs are carried out on damaged lawns, holes are punched for trampled and compacted lawns to loosen the soil, and aesthetically affecting trash is also removed from the lawn.

The mowing time can generally be mowed once a month or so, but the last mowing of the lawn before wintering should leave 6 8 cm of stubble, so as to facilitate the normal wintering of the lawn. The fertilizer is mainly nitrogen fertilizer such as ammonia sulfate or urea, which can be sprayed or irrigated. Watering is subject to one-time thorough watering.

After autumn, underground pests such as ground tigers, mole crickets, beetles and other pests begin to be active in the ground, and ground insect removal can be used to control underground pests in soil increase, and the effect is not obvious.

Fourth, the winter management of the lawn

Turfgrass has entered the dormant period in winter, most of the aboveground parts have turned yellow, and the physiological activities of turfgrass have basically stopped. In order to improve the ornamentality, we can spray chlorophyll to prolong the green holding period, with unexpected effects. During the dormant period of the winter lawn, the dead grass layer is removed.

Turfgrass is susceptible to low temperatures, and can be mitigated by spraying the leaves with magic frozen water or watering the roots when the soil is not frozen before winter.

January: There is basically no maintenance work to be done, but the lawn should be protected from excessive trampling to avoid damage and severe wear and tear. Do a good job in the year's lawn maintenance work plan, including the purchase of chemicals, fertilizers, tools, machinery and equipment and machine maintenance.

February: If the temperature is high, the management of early spring should be strengthened to check the budding and regreening of the lawn. In case of drought, it should be watered appropriately.

March: Comprehensively inspect the soil leveling of the lawn, and the low-lying areas of the lawn should be appropriately paved with a thin layer of fertilizer. When the low-lying area is more than 2cm, the lawn should be shoveled first, and then filled with fertile soil, and then the removed lawn should be restored.

And poured through the water, suppressed and leveled.

For lawns that are over-trampled and the soil is compacted, apply multi-tooth tools to loosen the soil surface, grass roots, water or fertilize, and then suppress and level.

Replant the missing lawn in time.

April: In early January, that is, around the Qingming Festival, the temperature warms, the summer green grass begins to enter the recovery and growth stage, and the winter green lawn begins to sprout. Obvious signs are also set up to restrict visitors from entering.

The first mowing should be started in mid to late then, leaving the grass at a height not exceeding.

If the lawn is found to have poor growth and abnormal color, fertilizer should be applied in time to promote the green leaves to regreen. Pull out weeds in a timely manner.

May: The lawn enters the vigorous growth period (pay attention to the newly planted lawn grass), which is also the beginning of regular lawn mowing, generally cut once every 10 or 15 days, and the stems and leaves are upright such as ryegrass.

Stick grass and purple fescue are pruned every 10 days, and they are creeping like knotted weeds.

Manila, dogtooth roots.

Cut once every 15 days. The mowing is required to be smooth and beautiful, the general height is controlled within the limit, and the lawn is required to be full, and if the ground is exposed, it should be replanted immediately.

June: The lawn enters the summer maintenance and management stage, and in the rainy season in the first and middle of the year, there is more rain, so attention should be paid to drainage to prevent the lawn from accumulating. In the second half of the year, it is necessary to enter the high temperature and drought period, and it is best to loosen the topsoil with multi-tooth tools such as nail rakes before drought-resistant watering, so as to improve the soil water storage capacity.

Watering should be scheduled before 10 a.m. and after 3 p.m. If earthworms are found.

To dig the soil, you should find the earthworm hole in time, inject 1 2 tablespoons of carbon disulfide to fumigate, or use 1000 times trichlorfon.

Liquid poisoning. Mowing is also done once every 10 to 15 days, and if the weather is particularly dry, the mowing grass can be left in the lawn as it can reduce ground evaporation.

July/August: Same as June.

September: This month belongs to the maintenance period, and the mowing interval can be appropriately extended, generally 20 days. Remove any remaining grass from the lawn.

October: The regular mowing work ends this month, and the last mowing can appropriately increase the length of the grass by 5 6cm, so as to facilitate the normal wintering of the lawn. At the same time, remove debris in the lawn and make up for the lack of lawn.

November: Remove fallen tree leaves from your lawn and keep your lawn clean.

December: last mowing with a height of 5 6 cm and compound fertilizer applied at the same time. (Mainly to promote early germination in the coming year).

According to the annual plant growth law and climate characteristics, formulate a year-round maintenance plan for greening management.

The climate can be roughly divided into four phases: namely: spring and dry season; wet rainy season; autumn dry season; Frost season.

1) One-year management plan for mixed turf.

1. Spring and dry season: (February 1 - May 10).

Climatic characteristics: the temperature is rising day by day, the weather is dry, the wind is strong and the rain is less; Warmer daytime temperatures; Temperatures are lower at night, with occasional light frost; It is characterized by a large temperature difference between day and night. The lawn is beginning to grow again, mainly due to the increasing demand for water and fertilizer.

The focus of conservation is to ensure that the lawn survives and regreens as soon as possible.

Specific management measures:

1) Pruning: Timely pruning according to the growth of the lawn; Every 10-15 days;

2) Irrigation: According to the environmental conditions of the lawn site, determine the amount of watering every 1 or 2 days, and provide water when the temperature rises;

3) Fertilization: depending on the growth of the lawn and the water conditions, an appropriate amount of nitrogen and potassium elements should be supplemented, and foliar fertilization can be used to supplement nutrients for local lawns; Pay attention to avoid fertilizer damage and grass growth;

4) Weeds: weeds on the lawn, which are manually removed;

5) Diseases and insects: pay attention to the control of leaf spot disease and noctuidae pests.

2. Wet rainy season: (May 19 - September 10) Climatic characteristics: the rainy season has begun, with the increase of rain, the environmental humidity increases, the grass growth rate accelerates, and the focus of maintenance is grass cutting and the prevention and control of pests and diseases.

Management measures: (1) Mowing: The lawn is in the fast growing season, and it should be mowed once every 8-9 days; When mowing the grass, seize the opportunity to do so; (2) Irrigation:

Depending on the weather conditions, if it does not rain for a few days, it is necessary to carry out appropriate watering to replenish the moisture of the lawn in time.

2) General lawn maintenance.

Month. 1. Weed control: apply herbicides 2 to 3 times, or use artificial methods to control the spread of weeds.

2. Irrigation: irrigation if necessary.

3. Prevention and control of diseases: brown spot, blight, leaf spot disease began to occur, sprinkler irrigation preventive fungicides, such as carbendazim, mancozeb and chlorothalonil, etc.

4. Prevention and control of armyworm: armyworm can occur in 2 to 4 generations a year, which is extremely destructive to the lawn. Timely detection is the key to armyworm control. Within 3 instars, 1 2 insecticide applications can be controlled.

August. 1. Sow new lawns: Early autumn is the best time to plant new cool-season lawns.

2. Prevention and control of diseases: high temperature and high humidity are the conditions for the occurrence of many diseases. Fungicides are applied, sprayed every 5-7 days, and applied 2-3 times consecutively.

September. 1. Fertilization: Autumn fertilization is the season with the most fertilizer in the year. Fertilization promotes lawn restoration, and the application rate should be higher than in March.

2. Vertical pruning: Remove dead grass through vertical pruning to create conditions for the growth of new grass.

3. Reseeding: Select excellent varieties and reseed the sparse lawn.

4. Prevention and control of rust: see April for methods.

October, November.

1. Fertilization: Fertilization in late autumn can increase the green period of the lawn and return to green early.

2. Clean up fallen leaves: If there are fallen leaves on the lawn, clean them up in time to prevent damage to the lawn.

December. 1. Carry out winter irrigation in time.

In June

The lawn should be mowed regularly during the summer maintenance management phase, and the blades should be kept sharp. The trim height should be appropriately high, generally around 6 cm.

Spray pesticides in time after each pruning to prevent bacterial infection. The main pesticides are carbendazim, mancozeb, methyl tobuzin, etc.

Fertilization should be based on potassium fertilizer, avoid nitrogen fertilizer, and the amount of fertilizer should be 15 grams of square meters as the standard.

Watering should avoid high temperature time, try to water in the morning, and avoid standing water on the surface.

Lawn maintenance requires technology, no technology is all weeds can not become a lawn, friendly reminder must not sow grass seeds, must be lawn laying.

It is mainly general maintenance and spraying fungicides.

Summer is the time when lawn diseases are at their worst, so spray lawn-specific drugs regularly.

Lawns are susceptible to disease after mowing, so lawn mowers need to be disinfected every time they run out of use.

Watering and fertilizing.

What to do if your lawn is dry? How to maintain it in summer?

Lawn Maintenance:

1. Weeding and pruning

For the lawn is the need to regularly remove weeds, spring is generally the lawn growth season, but also the season of weeds luxuriant, to pull out the weeds, to prevent it from affecting the growth of the lawn, if the weeds grow too much, will rob the lawn of water and nutrients, so that the lawn to stop growing, the consequences are very serious. In addition, it is not okay for the lawn to grow too fast, it will affect the appearance, and it is also easy to breed diseases and pests, so it is necessary to mow regularly to maintain the flatness of the lawn.

2. Loosen soil and ventilate

At the beginning of the growth of the lawn, the root system will be relatively dense and intertwined, so that it is easy to accumulate water in low-lying areas, resulting in root rot, and if the lawn is trampled too much, the soil will become compact, affecting root breathing and drainage, so the lawn needs to be loosened. A common method is to use a hole punch to punch the lawn to keep the soil ventilated and breathable, and the depth of the hole is about four centimeters, and the hole can be mowed after punching.

3. Fertilize and water

Water and fertilizer management is also very important for the lawn, in order to promote the tillering growth of the lawn, it is necessary to apply some compound fertilizer, which can better promote the tillering of plants, improve resistance, and make the lawn grow better. Watering should be carried out after fertilization, and there needs to be sufficient water during the lawn growth period, and there must be enough water to make the lawn grow quickly in the spring, and each watering should be thoroughly watered to let the root system deepen, and the number of watering times in summer should be more.

4. Pest control

Many lawns are susceptible to pests and diseases, so they need to be controlled in advance, and regular mowing should be done to clean up grass clippings and debris so that the lawn is not obscured. And it is necessary to check it from time to time, and if there are pests and diseases, it must be dealt with in time, and pesticides can be sprayed to prevent large-scale wilting of the lawn.

Mowing is an important job in lawn maintenance, almost throughout the entire growing season of turfgrass, the general lawn should be mowed at least 4-5 times a year, and for some highly managed lawns mowing up to hundreds of times a year, this issue will talk about the technical points of lawn mowing throughout the year!

Number of mowings for different types of lawns:

Cool-season lawn: Enters the dormant period in summer, generally mowed once every 2-3 weeks, in spring and autumn when the temperature is suitable and rainfall is abundant, the plant grows rapidly, and the pruning frequency is higher than that in winter and smiling summer, at least once a week.

Warm-season lawns: dormant in winter and slow growth in spring and autumn, so the frequency of mowing of warm-season lawns should be higher in summer than in spring and fall.

Lawn mowing height:

The basic principle of lawn mowing is the 1 3 principle. This means that each time you mow it, the cut part should not exceed 1 3 of the natural height of the turfgrass (the height before cutting). When the height of turfgrass is greater than 1 2 of the suitable height for mowing, it should be pruned according to the principle of 1 3.

Do not harm the rhizome, otherwise it will affect the normal growth of turfgrass due to the imbalance between the growth of aboveground stems and leaves and the growth of underground roots.

Note: In the summer, to increase the turf's tolerance to heat and drought, cold-ground turfgrass can be kept higher.

Mowing of the winter lawn:

Generally speaking, lawn mowing starts in March and ends in October. However, after the beginning of winter, if the turf grass grows too long, it can be mowed, in addition, as the temperature drops in winter, the lawn will gradually enter the yellowing period, which is very prone to fire, especially in places with frequent personnel activities, so the last mowing should be carried out around mid-November.

What are the precautions for lawn mowing?

1. The direction of mowing can not be fixed: each time the mowing should be slightly changed (change the imitation line of the mowing road), so as to avoid the soil in the lawn due to uneven squeezing and the wheel pressure groove.

2. When the same lawn is mowed, the same way cannot be used: it is necessary to prevent repeated mowing in the same place and in the same direction to avoid the grass growth weakening and the phenomenon of "texture".

3. Can not be watered and fertilized immediately after pruning: the wound is still healed after pruning, and it is easy to be attacked by pests and diseases.
