Tall Fescue Lawn Autumn Management Points
By the end of the summer and the arrival of autumn, the second growth peak of Tall Feather Turfgrass has arrived. In order to ensure that the tall fescue turf can grow robustly, it is the time to smoothly manage the winter. Remove grass damage For well-grown tall fescue lawns, weeds are difficult to grow through normal pruning. For poorly growing lawns, especially for newly-established lawns, the accumulation of nutrients is very short, and the number of tillers is small, coupled with the high temperatures that cause the lawn to sleep and die, the weeds will grow vigorously. The turfgrass died due to excessive trampling, and weeds will grow on the plane. Therefore, weeding should be used to remove the weeds. A small amount of weeds should be removed manually. Herbicides should also be used for weeds. Pruning as soon as possible for the lawn to safely summer, the summer will generally reduce the frequency of pruning, improve the height of the lawn. Therefore, tall fescue turf grasses are relatively slender. During the peak of growth in the fall, choose a pruning as soon as possible in the morning or evening after the dew is dry to promote the rapid growth of the lawn and increase the birth. After that, trim once a week or so, leaving a 5 to 6 cm height. As the weather gradually turns cold, the growth rate of turfgrass slows. In order to make it able to have enough nutrients for wintering, the number of pruning is gradually reduced after late autumn, and the height of pruning is appropriately increased. Pay close attention to the clean high temperature weather caused many tall fescue lawns to die. In pruning, the trimmed grass clippings are not completely removed, and the formation of the weed layer accumulates. The existence of a subtilis layer is not conducive to the ventilation and ventilation of the lawn. It is also extremely beneficial to the occurrence of diseases and insect pests. The large lawns are equipped with special clearing and drying machinery. For small lawns, some solid beddings can be customized for manual removal. Through rinsing, it can also achieve the purpose of scratching the turf, inhibiting the growth of moss and algae. Fertilized and watered Tall Fescue lawns are generally not fertilized during the summer, especially without nitrogen fertilizer. In the cool autumn climate, it is necessary to intensify fertilization, promote more turfgrass, and ensure the safe wintering of the lawn. At the same time, a robust lawn can delay the yellowing of the lawn and extend the green period. Fertilizer can use economical and practical common nitrogen, phosphorus and potassium compound fertilizers. In order to prolong the green period, the amount of nitrogen fertilizer can be appropriately increased, urea can be added to the compound fertilizer, and applied to the lawn together. After each fertilization, water should be immediately poured to allow the fertilizer to penetrate into the soil. Watering at the same time can remove the fertilizer stuck to the grass and avoid burning the leaves. Prevention and treatment of diseases due to pruning, desiccation, fertilization and other effects, will cause a lot of wounds on the turfgrass, bacteria can easily invade from the wound, resulting in turfgrass disease. Therefore, after completing the above work, spray protection should be performed immediately. Medicinal agents such as thiophanate-methyl, chlorothalonil, triadimefon, etc. may be used. Immediately after replanting, for the parts that have died in the film, after doing a good job of weeding and loose soil, depending on the weather conditions, the original varieties of grass seeds should be selected for timely reseeding at the end of October, and the dosage should be 35 g/m2.
