Purslane (Portulaca oleracea) can become a bothersome weed in lawns, flowerbeds, vegetable gardens and even between the cracks in your sidewalk. It’s a small, low-growing succulent with fleshy leaves and insignificant flowers containing plenty of seeds, which drop to the soil and grow into more plants. But purslane is edible—and nutritious, with good quantities of omega-3 fatty acid and vitamin C, making it a good antioxidant. Also, purslane is cherished in France and used in salads in fancy restaurants. One of the ways you can get rid of purslane is to pull it out by the roots and add it to your meals.
Getting Rid of Purslane
Prevent this plant from invading your yard by not introducing it and by selecting planting stock and seeds of other plants that are free of weeds. If you use a lawnmower or any other garden tool that has been used in an area where purslane is known to exist, be sure to clean these items thoroughly before bringing them onto your property.
Pull out any purslane with your hand weed puller tool immediately upon discovering it. Be sure to get the entire root system and try to weed it before it flowers and sets seeds.
Spread mulch in areas where purslane is known to exist. You can even use cardboard to smother the purslane underneath it.
Solarize the soil in areas with heavy infestations of purslane. To do this, spread a sheet of thick clear plastic over the soil area for four to six weeks during the warmest time of year. Anchor it with rocks or bricks around the edges. All plants and their seeds under the plastic will cook.
Use chemical herbicides for severe infestations of purslane. Home gardens usually do not require you to resort to this control. Both pre-emergent and post-emergent herbicides can be effective in controlling purslane. Recommended pre-emergents include dithiopyr and pendimethalin. Post-emergents include Dicamba, MCPP, MSMA and 2,4-D.
