White clover (Trifolium repens) is a common broadleaf weed that many homeowners find creeping into their lawns. It is one of the most prevalent perennial weeds in Kansas and across the United States, and you probably have some growing in your lawn right now!

White clover is a broadleaf weed that’s commonly found in turfgrass throughout Kansas City. It has 3 rounded leaflets that are usually bright green in color, which typically show off a faint white chevron shape (but not always). These leaves are accompanied by tiny white flowers as the plant matures. White clover can grow between 6 and 12 inches tall, but it is typically only 2-4 inches when found in residential lawns.
White clover is a low-growing perennial weed that thrives in many types of soil and climatic conditions. It tends to grow in patches rather than as individual plants, forming dense clusters that stand out against the surrounding grass. It has a lower growth habit than most turfgrasses, giving affected lawns an uneven appearance. Since it remains green even during drought conditions, it can become particularly noticeable when the surrounding grass turns brown.
Key Characteristics:
While white clover does have some ecological benefits, such as attracting pollinators and improving soil fertility, most homeowners view it as a weed that disrupts the uniformity of their lawns. Despite any ecological benefits, bees and pests are not typically unwanted in residential lawns, which is another reason so many homeowners want to rid their property of white clover as quickly as possible. Some of the primary reasons why white clover is considered undesirable include the following:
White clover is a highly adaptable plant that spreads through both vegetative and seed propagation. Its primary method of expansion is through stolons (above-ground stems) that root at various points as they creep across the soil. These stolons allow white clover to form dense mats that choke out surrounding grass.
In addition to its creeping growth habit, white clover also produces seeds that can remain viable in the soil for years. A single seed head can produce up to 100 seeds that are often spread by wind, animals, or foot traffic, making it easy for clover to establish itself in new areas. Because the seeds are highly durable, they can germinate even after lying dormant for extended periods.
Most troubling of all for your lawn, clover is also a survivor in adverse conditions. Unlike many common turfgrasses, it can thrive in compacted, nutrient-poor soil where grass struggles. Its ability to fix atmospheric nitrogen through a relationship with bacteria in its roots allows it to flourish in areas with low fertility, giving it a competitive advantage over grass in nutrient-deficient lawns.
Several factors contribute to the presence and spread of white clover in lawns. The exact root cause is not always easy to identify, but any lawn that is neglected or improperly cared for is at risk of a white clover invasion. Understanding these conditions can help homeowners take proactive steps to reduce or eliminate it. Below are some of the most common causes of white cover infestations.
If white clover has already taken over large areas of your lawn, a selective broadleaf herbicide can help eliminate it without harming your grass. Look for products containing ingredients like 2,4-D or dicamba to target clover while sparing most turfgrasses in the surrounding area. For minor infestations, manually pulling clover can be effective, but leaving fragments of the taproot intact in the soil could result in new weeds forming.
The most effective way to control white clover is to take preventive measures. Preventing white clover in your lawn is usually just a matter of following a good maintenance routine to encourage healthy grass growth. Follow the tips below to keep your lawn weed-free.
1) Improve Soil Health: Since white clover thrives in low-nitrogen soil, regular fertilization can help suppress its growth. Use a balanced lawn fertilizer with a higher nitrogen content to encourage grass growth and discourage clover. Organic options, such as compost or manure, can also improve soil fertility over time.
2) Mow at the Right Height: Mowing your grass slightly taller, about 3 inches or higher, can help shade out white clover and prevent it from spreading. Taller grass provides more competition, making it harder for clover to establish itself. Avoid scalping the lawn, as this weakens turfgrass and creates ideal conditions for clover.
3) Aerate and Dethatch Your Lawn: Compacted soil makes it easier for clover to take over. Aerating your lawn once or twice a year helps loosen the soil, allowing grass roots to grow deeper and access more nutrients. Dethatching also removes excessive organic material that can harbor clover and other weeds.
4) Water Properly: Deep, infrequent watering encourages deep root growth in grass, making it more resilient to drought and competition from clover. Frequent, shallow watering favors weeds like clover, which can quickly take advantage of weak grass.
5) Reseed Bare Spots: After removing clover, reseed bare areas with high-quality grass seed to prevent reinfestation. Thick, healthy grass is the best defense against future weed invasions.
