When to plant Bermudagrass seeds
The web tells everyone about the knowledge of when to plant Bermudagrass seeds and the planting methods and timing of Bermudagrass in the field of green plants and flowers. Next, the editor will introduce them.
Bermudagrass, scientific name Bermuda, is a low矮草本 plant of the Gramineae family and Bermudagrass genus. The culm is thin and tough, the lower part creeps on the ground for a long distance, often producing adventitious roots at the nodes, up to 30 cm high, the culm wall is thick, smooth and hairless, and sometimes slightly compressed on both sides.
The leaf sheath is slightly keeled, the ligule is only a ring of villi; the leaf blade is linear, usually hairless on both sides. The spikelet is grayish green or purplish, small flowers; the anther is light purple; the stigma is purplish red. The caryopsis is oblong cylindrical. Flowering and fruiting from May to October.
It is widely distributed in the provinces south of the Yellow River and in warm regions all over the world; it often grows near villages, roadsides, riverbanks, and wasteland slopes. Its rhizomes spread strongly, widely covering the ground, and are good soil conservation plants, commonly used for laying lawns or playing fields; but when growing in orchards or cultivated land, they become harmful weeds that are difficult to eradicate. The type specimen was collected from southern Europe. The rhizomes can be fed to pigs, and the leaves are liked by cattle, horses, rabbits, chickens, etc.; the whole herb can be used as medicine, having the effects of blood purification and antipyresis.
Bermudagrass has developed rhizomes and long creeping stems, with strong creeping stem expansion ability, up to 1*-2cm long, each node takes root on the ground, and can propagate into new plants; the leaves are lanceolate or linear, 2-10cm long, 1-7cm wide, with two dark lines on both sides of the main vein, and the ligule is short. Bermudagrass prefers warm and humid climates and moist soils, is not cold-resistant, grows poorly in cold climates, and is easily affected by frost; it likes light and heat (can tolerate 43-degree high temperature), grows suitable when the daily average temperature is above 24 degrees; when the daily average temperature drops to 6-9 degrees, the growth slows down and begins to turn yellow; when the daily average temperature is 2-3 degrees, its stems and leaves wither, and it relies on its rhizomes and creeping stems to survive the winter, and grows from the dormant buds of the overwintering part the following year.

Cultivation Techniques
Bermudagrass sowing is generally carried out in late spring and summer, when the temperature is high, and the seeds are easy to germinate, with a sowing rate of 30-35 grams/square meter. After sowing, the soil should be covered immediately to ensure that the seeds and soil are fully in contact, with a soil cover thickness of 2MM directly accompanied by soil broadcasting is also possible. After sowing, water should be irrigated in time, and fogging pipes should be used for irrigation equipment, which has a high degree of atomization and can prevent large water droplets from washing the seeds out of the soil. Then, a layer of straw or non-woven fabric can be covered to reduce evaporation and benefit seedling growth.
It is extremely important to level the lawn bed before planting, as an uneven lawn bed will cause many problems for future lawn management. Before tilling, all construction waste such as stones, broken tiles, various weeds, and withered leaves in the lawn bed should be completely cleaned up. Tilling is divided into rough and fine tilling, with a recommended tillage depth of 20-25cm, leveling the lawn bed surface, loosening the tillage layer, and using a light-duty roller (150-200kg) to roll once. To ensure good growth and development of Bermudagrass, sufficient base fertilizer should be applied before tilling, mainly organic fertilizers such as decomposed chicken manure and human urine manure. Irrigation and fertilization
Irrigation is one of the main methods to ensure the timely and adequate supply of water required for the growth of lawn grass and an important measure for lawn maintenance and management. Due to the relatively shallow root distribution of Bermudagrass, irrigation should be carried out in time during dry summers. When irrigating, it should be watered thoroughly at once, and no water should be stopped halfway, so that the roots can spread to the surface, reducing their drought resistance. The amount of water and the frequency of irrigation depend on the specific situation.
Fertilization can provide the nutrients required for lawn grass, and fertilization is one of the main factors affecting the resistance and quality of the lawn. Bermudagrass lawn fertilization can be carried out in early summer and mid-summer, with fertilizers mainly containing N, P, and K, with an application rate of about 30 jin per mu. After fertilizing, irrigation should be carried out in time to fully dissolve and infiltrate the fertilizer into the soil for Bermudagrass to absorb and utilize, improving fertilizer utilization.

Maintenance Management
Lawn maintenance management is an important measure to obtain and maintain high-quality lawns. If the maintenance management is improper, the quality of the lawn will decrease and its lifespan will be shortened. The main measures for lawn maintenance management include lawn mowing, irrigation, and fertilization.
Mowing Management
Mowing is the most basic and important task in lawn maintenance management. Mowing can control the height of lawn grass growth, keep the lawn flat and beautiful, and increase the density of the lawn. At the same time, mowing can also suppress diseases caused by dense branches and leaves. Before mowing, stones, wires, branches, plastics, and other debris in the lawn should be cleared to avoid damaging the lawnmower and affecting the mowing quality. The mowing frequency mainly depends on the growth rate of Bermudagrass. The mowing frequency is different at different times. The mowing height should follow the 1/3 principle. Bermudagrass, as an excellent soil conservation and slope protection plant, is generally mowed 2-3 times a year.
Disease and Pest Control
Diseases and pests severely affect the quality of the lawn. As long as the environmental conditions are suitable, pathogens will infect the lawn grass, causing diseases in the lawn. Timely mowing, improving the ventilation and light transmission performance of the lawn, can reduce the occurrence of diseases and pests. At the same time, the cut grass should be removed from the lawn in time. Scientific and reasonable fertilization should be carried out according to the different growth periods of Bermudagrass, applying more N fertilizer in spring; more P and K fertilizers in summer and autumn to improve the resistance of Bermudagrass to diseases and pests. For lawns with diseases and pests, fungicides and insecticides should be sprayed in time for prevention and control, and preventive measures can be taken for lawns without diseases and pests.
Bermudagrass has strong competitiveness with weeds, and general weeds are difficult to invade. Weed control should adhere to the principle of "removing early, removing small, and removing completely." Before Bermudagrass forms a lawn, there may be weeds invading, which should be removed manually in time or selectively herbicides should be sprayed for control.
Lawn establishment: Bermudagrass is a perennial herbaceous plant of the Gramineae family and Bermudagrass genus, which is warm-season grass. It has rhizomes and creeping stems, with strong creeping stem expansion ability. The leaves are dark green, slightly shade-tolerant and drought-tolerant, prefer warm and humid conditions, and have certain cold resistance. The suitable soil pH range is very wide (5.5-7.5), among which, it grows better in moist and well-drained medium to heavy clay soils, and also grows well in light sandy saline-alkali soils. The optimal growth temperature is 20-35℃, when the temperature reaches 24℃, the growth is pleasing; when the daily average temperature drops to 16℃, the growth stops; when the soil temperature is lower than 10℃, it begins to fade and gradually enters dormancy, with a green period of about 250 days in the East China region. The sowing time for Bermudagrass in East China is from March to September every year. If sowing too early in spring due to low temperature will lead to slow germination and affect the formation speed of the lawn; if sowing too late in autumn due to low temperature will lead to slow lawn growth, and the seedlings cannot survive the winter safely. The manual sowing rate is 10-12g/m2; the spray seeding rate is about 15g/m2, and it can also be mixed with other warm-season or cold-season grass species.
Suitable Planting Areas
Due to the strong trampling resistance, invasiveness, regenerative ability, and resistance to harsh environmental conditions of Bermudagrass lawns, as well as the developed root system, they are often used for landscape greening in machine scenes, soil and water conservation on dykes and reservoirs, and slope stabilization greening projects on both sides of highways and railways, making it a good soil and water conservation plant variety. Choosing high-quality grass seeds from Seed China, the improved Bermudagrass lawn can form a strong, high-density lawn, with strong invasiveness, delicate leaf texture, lawn color ranging from light green to dark green, with strong rhizomes, creeping growth, and can form dense sod, with a wide and deep root distribution, and can be used for golf course construction, park green spaces, and villa area lawns.
