Only in USA is purslane (Portulaca oleracea) considered a weed. Everywhere else, it's part of dinner. Whether or not one wants to eat it, it makes a great ground cover under taller plants, shading the ground. A cousin, P. umbraticola is sold at stores as "ornamental purslane," the other moss roses. Without seeing a bloom, it's impossible to say which yours is.

Purslane is an annual plant that spreads by seeds and itty bitty parts of the plant that root and then grow, a succulent. That glyphosate probably killed the plants that were growing but new ones germinated from seeds in the soil, something glyphosate products will not do anything to stop.

Using a glyphosate product to control Purslane is overkill since that creates a good place for more Purslane to grow, as well as distributing a potential carcinogen.

Thank you all VERY much indeed! Looks like I've got my work cut out for me... wish me luck!

Happy Trails,

BTW, is there any way to remove this stuff from my lawn?

Thanks Again,

Weed and feed should work. Haven't tried it personally tho.

I found a diff kind, P. amilis in our lawn & moved a couple hundred plants to this bed to be ground cover.

This one is a P. umbraticola, sold in stores as ornamental purslane/the other moss roses.

The first image: Purslane, did you know you can eat this! Its full of vitamins! The second image: Spurge, poisonous and not to be eaten.

Purslane is my favorite edible weed. I wish more people would appreciate the many uses of "weeds".

Looking back over this discussion, I forgot to ask, why is there a strip of bare ground? If we take a step back & look at the big pic, there might be an easy-peasy solution to your ground cover issues.

2-4-D, broadleaf weedkiller will kill it.

The typical hardware store forms of glyphosate have trouble killing these because they don't have enough surfactant in them. It just runs off the leaf surface. They only add enough surfactant to kill more typical weeds like dandelions and annual grasses. Any properly diluted agricultural surfactant (or possibly, just 1/2 tsp. dish detergent per gallon) will allow them to be killed; you should still probably use a higher dilution.

2,4-D or various other auxin-type herbicides will kill them too, again, with enough surfactant.

I pull Euphorbia usually, though, to try to get the seeds. They aren't too hard to pull in my soils, at least, after rains.

"Using a glyphosate product to control Purslane is overkill since that

Dairy milk, peanut butter, and red meat are also potential carcinogens. Please, do not spread these items on your garden.

Agree with you though, that, any patch of bare soil is a magnet for weeds...and is the "root" cause that needs to be corrected.
