In addition to weeds, maintaining healthy turfgrass is a crucial aspect of lawn care. Weeds often have stronger vitality than the grass you've planted, and if not removed promptly, they can absorb essential soil nutrients, hindering the growth of your desired grass. Proper weed control ensures a lush, even lawn and promotes long-term turf health.
(1) Manual Weeding
Manual weeding is an effective method for removing small or hard-to-reach weeds that are not suitable for herbicides. This process should be organized by zones, sections, or blocks, with consistent, scheduled efforts to ensure thorough coverage. When performing manual weeding, it's important to kneel rather than sit or bend over, as this helps maintain posture and prevents strain. Use tools like a trowel or weeding fork to remove the entire root system along with the weed, rather than just the above-ground portion. After pulling out weeds, dispose of them in a trash bin immediately to prevent reseeding. Work in blocks, patches, and areas to ensure complete coverage and efficiency.
(2) Herbicide Application
For large infestations of stubborn weeds, selective herbicides can be used under the guidance of a professional gardener or technician. The application must be approved by the greenery maintenance manager, and the correct type of herbicide should be selected based on the specific weed species and grass type. When spraying, press down the spray gun to avoid mist drifting onto nearby plants. After use, thoroughly clean the sprayer, including the gun, barrel, and machine, using clean water. Do not pour the rinse water near plants or in sensitive areas. Avoid applying herbicides near flowers, shrubs, or young seedlings, and never use them on any type of grass unless specifically recommended. Always keep a record of herbicide usage for future reference and safety.
(3) Weed Control Quality Standards
The lawn should not have any grass taller than 15 cm, and no more than five weeds per square meter should exceed this height. The entire lawn should be free from visible broadleaf weeds, and there should be no blooming weeds present. These standards help maintain a neat, well-managed appearance and ensure the long-term health of the turf. Regular inspections and timely interventions are essential to meet these quality benchmarks.
