Strip renewal method: For grasses with stolons and segmented roots, such as buffalo grass, zoysia grass, and dogtooth grass, after growing to a certain age, the grass roots are dense and aging, and the spreading ability is degraded. You can dig out a 50 cm wide strip every 50 cm, add peat soil or compost soil, and re-level the empty strip. After one or two years, it will be full, and then dig out the remaining 50 cm. Repeat this cycle, and it can be fully renewed once every 4 years.
Root cutting renewal method: Due to soil compaction, the lawn degenerates. We can regularly use a puncher to make many holes in the lawn ground on the built lawn. The depth of the hole is about 10 cm, and fertilizer is applied in the hole to promote the growth of new roots. In addition, you can also use a nail barrel with a tooth length of three or four centimeters to roll, which can also loosen the soil and cut off the old roots. Then spread fertilizer on the lawn to promote the germination of new buds to achieve the purpose of renewal and rejuvenation.
For some plots with thick dead grass layer, compacted soil, uneven lawn grass density and long growing period, rotary tillage and root cutting cultivation measures can be adopted. The method is to use a rotary tiller to turn the soil once, and then water and fertilize, which can not only achieve the effect of cutting off the old roots, but also make the lawn grass produce many new seedlings.
Replanting turf: For slight dead grass or local weed invasion, remove the weeds and replant seedlings in a timely manner. The turf should be trimmed before transplanting, and it should be stepped on after replanting to make the turf and soil tightly combined.
One-time renewal method: If the lawn is degraded and dead grass reaches more than 80%, it can be turned over by a tractor and replanted. Strengthen maintenance and management after planting, and the replanted lawn will soon become strong.
