Mallow weeds in landscapes can be especially troubling for many homeowners, wreaking havoc in lawn areas as they seed themselves throughout. For this reason, it helps to arm yourself with information on mallow weed control. Keep reading to learn more about how to get rid of common mallow in the lawn and garden.

About Common Mallow Weeds

Common mallow (Malva neglecta) came from Europe to North America and is a member of the Malvaceae family, which also includes such desirable plants as hibiscus, okra and cotton. Depending on the climate it is in, common mallow weeds are annuals or biennials.

Frequently found in open areas, cultivated lands, gardens, landscapes and even new lawns, mallow weed control is a popular topic of conversation amongst gardeners. Mallow weeds are particularly troublesome in new lawns where they can produce a tremendous number of seeds long before a homeowner may even know that there is a weed control problem.

Mallow weeds have an extremely deep tap root and spread close to the surface of the ground. One plant can reach as far out as two feet. Leaves are rounded with two to five lobes and tiny pinkish white flowers appear in the spring, lasting through the fall.

Some people get it confused with ground ivy, whose stems are square, while the mallow is round. Although mallow weeds may be obnoxious to gardeners, the leaves are edible and taste lovely in salads.

How to Get Rid of Common Mallow

No matter how tasty mallow may be, it is not often a welcome visitor in the garden or lawn. Getting rid of this persistent plant is not an easy chore either. Mature mallow seems to be incredibly resistant to most common herbicides.

One of the best ways to control this weed in lawns is to make sure your turf is thick and healthy. A healthy turf will choke out the weed and not allow the seeds to spread.

If you have a small problem section, you can also pull the weeds before they go to seed, though all of this may prove ineffective, partly because seeds can lay dormant for years before sprouting. Controlling mallow can definitely be a frustrating task at best. Pulling, hoeing or weeding works well when plants are very young, and you must keep a constant eye to keep up on them.

If you choose to use an herbicide to reduce the number of mallow weeds in your landscape, be sure to read the directions thoroughly and take the necessary safety precautions. Herbicides work best, like weeding, when the plants are young and in their vegetative state. Do not allow pets or children on a sprayed lawn area immediately after spraying. Never eat a mallow plant that has been sprayed with an herbicide.
