Homeowners have a love-hate relationship with clover (Trifolium). Excessive growth of this benign weed in your yard may mean your soil is using clover to send you a distress signal. So while other plants and grasses in your yard may be barely limping along in low-nitrogen soil, clover will flourish. In addition to providing nitrogen to neighboring plants, clover attracts pollinators, which feed on the nectar of clover flowers. However, if you're really not a fan, there are a few ways you can prevent clover weeds from taking over your lawn.
