Common Mallow Weeds (Malleus vulgaris) are one of the most widespread weeds in gardens. They grow well in all types of soil conditions and thrive under a wide range of environmental conditions. Common mallow is a perennial weed that requires little care or attention from gardeners because it does not require much space to spread out. However, they do need regular pruning if they are growing too high or spreading out too far.

The leaves of common mallow are usually dark green with yellow margins. The flowers are white and have 5 petals each.

The fruit is a seed pod which contains several seeds. These seeds germinate when water is added to the soil around them, so watering should be done regularly during their growth period. Common mallow plants produce many offspring, but only one will survive to adulthood.

Common mallow grows best in sandy soils and prefers moist soil. It tolerates light shade, but can become very invasive if allowed to take over a large area.

If you live in an area where these plants are present, then you may want to consider controlling them before they overrun your garden!

Control Methods: Control Common Mallow Weeds With Herbicide Or Insecticidal Soil Fertilizer (ISF).

Herbicidal Soil Fertilizer: When using a herbicidal soil fertilizer, you mix it with the soil before planting your garden. The plants that grow in the soil will absorb the herbicide while they are growing.

The plants will be killed because the herbicide interferes with photosynthesis (which is how all plants make their food). Since common mallow grows best in sandy soils, it is very susceptible to this type of herbicide.

Insecticidal Soil Fertilizer: Like the name suggests, these contain ingredients that will kill many types of insects. Common mallow is susceptible to these types of soil fertilizers just like they are susceptible to others.

Again, since they grow best in sandy soils, they will easily absorb the insecticide.

Products With Sulfentrazone: Common mallow is extremely susceptible to products containing sulfentrazone. This chemical can be mixed with water or oil and directly sprayed onto the weed.

Products With Dicamba: Common Mallow can easily be killed with dicamba. This can be used as either a spray or through irrigation systems.

Products With 2,4-D: Common mallow is susceptible to 2,4-D. This can be used as a spray or through irrigation systems.

Products With Glyphosate: Like most plants, common mallow is extremely susceptible to glyphosate. It is best applied directly to the weeds with a sprayer.

Using Several Methods: If you have a lot of common mallow plants in your yard, then using several different methods will be the most effective way to kill them. Try using three different products with three different modes of action.

This will ensure that you kill all of the common mallow plants.

Add a Non-Selective Contact Herbicide: After you have sprayed the common mallow with several different herbicides, it would be best to use a non-selective contact herbicide on the rest of your yard. This will ensure that no other plants in your yard are damaged by the chemicals you will be spraying.

The only plant that will be affected is the common mallow because it was already weakened by the previous chemicals you sprayed on it.

Add An Herbicide That Will Evaporate And Persist: After using the non-selective contact herbicide, you will then want to use an herbicide that will evaporate and persist (such as glyphoste). These chemicals stay in the soil for a long period of time and will continue to kill more common mallow plants that attempt to grow in that area.

Using these methods will help you get rid of common mallow plants forever!

You should also know that it is illegal to sell or distribute common mallow plants. If you have any in your possession, then you need to get rid of them as stated on the product’s label.

You can also use a biological control for the common mallow which is a fungus (Puccinia monoica). The way this works is it infects and kills the common mallow plant by attacking its tissue.

This fungus can be purchased online and distributed throughout your yard using a sprayer.
