Remove weeds before flowering and fructification to prevent seed spreading. Mulching: During the seed stage, cover with sawdust, straw, or black mulch to effectively inhibit seed germination and seedling growth. Generally, this method is used in winter or spring. If the weeds have already flowered and fructified, use this method to isolate the seeds to prevent the seeds from falling into the soil. Pulling out: Before the weeds fructify, wear gloves or use tools to pull them out. The day before pulling out the weeds, water and loosen the soil with a spade, then dig deep to get the root. A weeding fork will help remove the roots completely. From then onward, observe the area regularly and immediately clear the new buds. Homemade herbicide: If weeds grow around plants that you do not want to hurt, you can mix an equal amount of hot water with vinegar to form an environmentally friendly herbicide. Then add a small amount of salt and detergent to spray on the weeds to prevent them from further growing. Plowing: Before cultivation, plow the soil, collect and discard the roots of perennial weeds, then expose them to the sun, bury them deeply, or use them for retting organic fertilizer and composting. Chemical control: Using appropriate herbicides can effectively remove the weed from the area. Note: When removing weeds, wear gloves to avoid direct contact with the weeds, especially for poisonous, thorny, and allergenic weeds. When removing weeds at the flowering stage, wear special masks to prevent allergic reactions caused by pollen inhalation.
