Once weeds are flowering and firm, it is difficult to effectively control them, so the best time for weeds to be removed is before flowering and firming; once flowering and firming, the seeds will spread very quickly and need to be removed frequently, and prevention should be made in the next year. Pull out: Before weeds are strong, wear gloves or use tools to dig out weeds. If the soil is difficult to remove due to drought, it can be used to thoroughly remove the roots of weeds after being irrigated with water. After removal, it can be used in conjunction with deep cultivation to prevent weed roots from remaining. This method is particularly suitable for weeds at the seedling stage or with a relatively low size. Pruning: Pruning before weeds can effectively control the spread of weeds, especially for annual weeds. Frequent pruning can suppress the growth and fruiting of weeds, which can effectively remove weeds that year. Tilling: Tilling the soil before cultivation, picking up and discarding the perennial weed roots, discarding, exposing or burying deeply, it can also be used to make organic fertilizer and compost with weeds. Chemical control: The weeds can be effectively removed by competing herbicides. Grazing: Use vigorous grass growing in autumn to compete with weeds. Appropriate fertilizers and good grazing management can increase the competitiveness of pasture turf and effectively suppress weed growth. Note: When removing weeds, you need to wear gloves to avoid direct contact between the body and the weeds, especially for some toxic, thorny, sensitive mucous weeds. When cleaning weeds during flowering, you need to wear a special mask to prevent allergies caused by inhaling pollen
