Lawn care can come with unique challenges. Sometimes, there are bare patches, or worse, bare patches where weeds have begun to grow. Or, perhaps your lawn requires too much water or simply takes too much work. But, there's an easy way to fix some of these issues—microclover. Microclover is a crop that can be grown mixed with your lawn’s existing grasses or planted as a total replacement. Ahead, we reached out to experts to explain what microclover is and weigh the pros and cons of using microclover in your yard.

What Is Microclover?

Microclover is a smaller variety of the more common Dutch clover, Trifolium repens, says Teresa Watkins, horticulturist and University of Florida Master Gardener. Microclover sits low in the grass—just 4 to 6 inches tall—so it doesn’t stand out like a weed and instead fills in the richness of the lawn. It can be used as a complete ground cover or to supplement an existing lawn.
Microclovers tend to be hardy and very cold-tolerant. They can be grown in colder climates up to USDA Hardiness Zone 2. At the same time, they can handle a little heat and can be grown in climates as warm as Zone 9 (though during a hot summer, they may go slightly dormant).
Benefits of Planting Microclover
Our experts outline some of the benefits of growing microclover on your lawn.
Erosion Control
Microclovers can help control erosion because they develop a relatively deep and fairly strong root system—roots that can help hold soil in place and prevent rain-induced washouts. "It is well known that clover species stop erosion and lower the need for fertilizers and herbicides," says Watkins.
Nitrogen Conversion
"[They’re] also good for converting climatic nitrogen into important nutrients used by turf and plants," says Watkins. Microclover is a member of the legume family—and like other legumes, it can take climatic nitrogen from the environment (a form useless to plants) and create a helpful form that can be utilized by plants and soil, increasing the health of the soil.
Reduced Mowing and Watering
"Growing shorter than the white and red clovers, microclovers can blend in most turf grasses easily and don't mind being mowed," says Watkins. "Microclover is also water-conserving, and its smaller, dense leaves can help prevent weeds."
Durability
Clovers tend to be pretty durable, so if your yard sees a lot of foot, pet, or wheel traffic—particularly concentrated in the same region—microclovers will generally stand up to the stress better than grass.
Disadvantages of Microclover

For all its many wonderful benefits, microclover isn’t without a downside or two.
Blossoms
One potential disadvantage is that microclovers do bloom. The blossoms tend to be less conspicuous and less abundant than those of other clovers, but some homeowners may think the blossoms look too much like weeds. The blossoms can also attract pollinators—generally a good thing! But it may not be ideal for anyone with insect allergies who spends time on the lawn.
That said, mowing will remove the blossoms.
Sun Requirements
Microclover needs plenty of sun; it won’t thrive as well in overly shaded areas. You may want to skip microclover if your lawn is overly shady.
Potential Spread
Your neighbors are another consideration. "The main disadvantage of clovers is that they do tend to spread, and you might end up with confused or angry neighbors," says Jennifer Rensenbrink, master gardener volunteer with the University of Minnesota Extension. "If you’re going that route, it’s best to talk with them first and make sure they understand why you’re planting it and why it’s great for lawns."
How to Establish Microclover
The specifics of seeding microclover will depend on whether you're adding microclover to your existing lawn or starting from a blank slate to achieve a lawn with solid microclover.
If you plan to add microclover to an existing lawn, prepare by mowing the grass short, then raking up any bare areas for seed. It's wise to test your soil pH before seeding (and amend as necessary) to give your microclover seeds the best possible start. "Microclover requires an organic-rich soil and full sun," says Watkins. You can mix the microclover seed with sand to make it easier to sow and then sow as instructed on the seed package. Keep the seed watered regularly during the germination period. With the right conditions, microclover can take about two months to become fully established, says Watkins.
Watkins notes that while microclover is a perennial plant, reseeding will still be necessary as you go along. "Microclover will need to be reseeded every three to five years or mowed each year only after the flowers have gone to seed," says Watkins.
