How to Identify and Kill Common Mallow in Your Lawn

Written by Chase Coates | Feb 16, 2023

Common mallow may have a sweet-sounding name, but it’s an aggressive weed that can quickly take over your Idaho Falls yard.

Often mistaken for ground ivy, this low-growing pest is much harder to eliminate due to its deep taproot and prolific seed production.

If you don't catch it early, mallow can survive even the hottest Eastern Idaho summers.

Identifying common mallow is the first step: look for rounded, geranium-like leaves with ruffled edges. Unlike many garden weeds, mallow is highly resistant to standard DIY sprays once it matures.


To truly banish it, you need a combination of pre-emergent barriers to stop seeds from germinating and professional-grade broadleaf treatments to kill established plants.

Here is how to identify common mallow in Idaho Falls, along with the best professional strategies to keep it out of your lawn for good.

First, What Does Common Mallow Look Like? 

This weed is easily recognized by its geranium-like leaves that have five or seven lobes. Its flowers seem small and drab compared to its dramatic display of leaves.

What Weeds Does Common Mallow Get Confused With?

Common mallow is often mistaken for ground ivy. How to tell the difference?

Ground ivy leaves are opposite on the main stem and have rounded edges. Mallow leaves have deep, ruffled edges. 


Also, if you crush a ground ivy leaf in your fingers, it smells like mint. If you crush a common mallow leaf, it smells like s’mores. (Just kidding. That would be cool, though.)

How to Get Rid of Common Mallow

Mallow produces many seeds, so using a pre-emergent herbicide in the spring will help prevent them from germinating.

Unlike other weed control products that kill weeds that have already sprouted, pre-emergent herbicides work ahead of time, preventing seeds of unwanted plants like mallow from germinating. They target the weed seeds before they have a chance to germinate.


Timing is everything. It’s important to apply the pre-emergent herbicides early enough because if you wait too late, they won’t be effective. Lawn care services in Idaho typically start applying pre-emergent around April 1.

When Is It Too Late to Treat Mallow in Lawns?

Missed your pre-emergent window? It happens. 

Broadleaf herbicides applied in mid-spring through early summer, when the plant is young and actively growing, can help, but mallow is a tough one.

How We Attack Common Mallow — and Other Pesky Weeds 

When you choose Lawn Buddies, you get one premium, six-visit lawn care program that includes everything your lawn needs to grow healthy and green, including weed control that’s perfectly timed throughout the year.

Most weeds are banished over the course of the six-step program. 


But some extra-tough weeds like common mallow sometimes require a different herbicide, which is an additional visit on top of the normal lawn treatment.

Controlling weeds is a process, not a one-shot deal.

A Healthy Lawn Helps Prevent Common Idaho Lawn Weeds

The best method of weed control is establishing healthy turf, including proper fertilization, watering, and mowing.

Weeds like common mallow hate a thick, healthy lawn. Dense grass crowds out weeds and blocks the sunlight their seeds need to sprout.


Weeds love to push through struggling lawns, taking over weak spots. So your best line of defense is to keep your grass thick, lush, and healthy with an annual lawn care maintenance program that supports strong roots. Then weed seeds will have a tougher time sprouting.
