Weed Control
A weed native to South America, three-lobed false mallow has spread to much of the tropical and subtropical regions worldwide. It is considered invasive in 53 countries and islands, including the United States, and often grows as an agricultural weed. Three-lobed false mallow grows rapidly in disturbed areas and outcompetes native species. It can invade overgrazed pastures, quickly replacing more nutritious species. Mechanical control, including mowing and hand pulling, is typically not effective unless the root is completely removed. Herbicides may not be effective at controlling three-lobed false mallow as it is generally tolerant to them.
How to Control It
For managing three-lobed false mallow, early spring is the best season, before the plant has started to flower and produce seeds. Here are a few organic or interesting methods to remove or control three-lobed false mallow:
Hand-pulling: Wear gloves and remove the plant by hand. Make sure to get out as much of the root system as you can to prevent regrowth. Dispose of the plants in a compost bin.
Solarization: This method works best in the summer. Lay down a thick, clear plastic sheet over the infested area and let the sunlight do its work. The heat from the sun will kill off the seeds and plants beneath the plastic.
Vinegar Spray: Mix white vinegar with a small amount of dish soap and spray it on the leaves of the plant, making sure not to get it on other desirable plants. The acidity of the vinegar will kill the mallow.
Mulching: Spread a thick layer of mulch over the soil surface to block sunlight and prevent the three-lobed false mallow from germinating.
Plant Competition: Planting fast-growing, competitive species can help outcompete and suppress the growth of three-lobed false mallow.
