Ryegrass is a perennial, clump-forming grass turfgrass with young leaves arranged in a foliate pattern in the leaf sheath. The leaf blades are smooth, but the veins are more pronounced than in grasses of early maturity. Perennial ryegrass prefers a warm, moist environment with cooler summers, so today we’ll introduce you to ryegrass lawn cultivation techniques.
Rye grass lawn cultivation techniques.
Ryegrass is suitable for growing in areas without severe cold in winter and summer heat, when the temperature is below -18 ℃ will produce frost damage, suitable temperature 27 ℃, soil temperature of about 20 ℃, 15 ℃ tiller more, spring growth is fast, hot summer is dormant, autumn also grows better. It does not tolerate drought and grows poorly in poor soil with lack of water. It is suitable for growth on slightly acidic, fertile soil with a suitable pH of 6~7. Perennial ryegrass regenerates faster and is more resistant to trampling. Disease resistance is lower than that of tall fescue and meadow fescue. According to the spike time, perennial ryegrass can be divided into early, middle and late types. Under the condition of less fertilization, the late type varieties have better lawn quality than the middle and early types because the stems grow less in midsummer.
Ryegrass establishment and management.
Perennial ryegrass is established by sowing seeds at a rate of 20-25 g/m2. Perennial ryegrass is rarely planted alone, except as a short-term temporary vegetative cover, and is usually mixed with other grasses. Seed germination is rapid, usually 3-7 days, and establishment time is about 45 days.
Perennial ryegrass can be mixed with other grasses for general lawns, golf courses, and tall grass areas. In the southern winter, perennial ryegrass can also be used as a supplemental seeding for warm season lawns. Perennial ryegrass is not tolerant of low mowing and the stubble height should be kept at 4 to 6 cm. It is less resistant to pests and diseases and should be controlled during the hot and humid season.
