Mallow

Description: Round green leaves. White to lavender flowers.
Peak Season: Late summer (July - August)
Treatment: Herbicide

Mallow is characterized by round, lobed leaves which are often confused with ground ivy. The leaf is attached to the stem from the back while ground ivy is connect from the center with a hairy top.

From May to October the flowers will bloom. They range from white to lavender in color.

When will I see Mallow? Mallow can be a perennial (it lives for years) or an annual (it lives through the season) depending on the species. Therefore, you may see it in your lawn throughout the year (from early spring to late fall) peaking during July and August.

How do I get rid of Mallow and how long will it take?

Mallow is one of the harder weeds to kill with a selective herbicide, but it can be done. Apply this every 5 to 6 weeks. You should start to see damage and withering to the leaves after the first or second application, with the plant completely killed after 6 consecutive applications. If you don't want to wait for the whole summer, you may consider weeding them by hand.

How do I prevent Mallow from infiltrating my lawn?

While there is no way to perfectly keep out all mallow, there are a few things you can do to help prevent new growth in your lawn. These include:

  • A Pre-emergence herbicide in April or May to help prevent germination.
  • Mowing your lawn on the second highest setting to help crowd out any potential growth and block out the sunlight.
