Is it clover or Oxalis, Jennifer? I canÂt tell from the picture, but thereÂs a good description at the link below. Both of them spread underground, and if itÂs Oxalis, when they produce seeds, they "shoot" them all over the place the same as sweet violets. Oxalis is a pervasive weed we were constantly fighting when I was in the green industry. Thank god I donÂt have any around here at this house, and whenever I buy something, I make absolutely sure there isnÂt any growing in the pot before I plant the whatever-it-is. Once you get it itÂs a nightmare. Since you want to get rid of itÂwithout chemicals!Âwhichever it is, I recommend TOTALLY saturating the ground, wait for it to completely soak in for several hours or over nite, and then very slowly pull/dig them out. "Slowly" in an attempt to keep as many roots attached as possible. Either will come back from any roots left in the ground. If the soil is soppy enough, you should be able to get quite a lot of it out, and then if you keep after it whenever it starts to grow back, you should be able to EVENTUALLY get rid of it. In areas where itÂs not growing into something you want to keep, yeah, go ahead and dig out enough soil to get all the roots and then replace it. That might take care of some major areas. But whatever you do, be absolutely certain you donÂt let any of it go to seed if it is Oxalis! Speaking of space invaders, if itÂlike bindweedÂgoes to seed, itÂs there ad infinitum! Skybird P.S. I looked at the pic on your other thread, and I canÂt tell what it is! If nobody else can identify it, wait till the first leaf or two develops and post another picture. Here is a link that might be useful: Clover vs. Oxalis - pdf

Are you sure it's not just the rootlets by which Trachelospermum sticks to surfaces? They look like parallel lines of little brown hairs running along the stems. They start off stuck together and if they touch a suitable surface they divide up into clinging root-like stickers. Your description would seem to fit.

NO You do not necessarily have to get rid of purslane. It is not a bad weed. It can depend on what is growing in the area. Tomaotoes will grow on top of it. Some places sell seeds of purslane. some people try to grow it. You are lucky to have purslane to pick for eating. from wikipidia Although purslane is considered a weed in the United States, it can be eaten as a leaf vegetable. It has a slightly sour and salty taste and is eaten throughout much of Europe and Asia.[2] It can be used fresh as a salad, or cooked like spinach, and because of its mucilaginous quality it is also suitable for soups and stews. Australian Aborigines used to use the seeds to make seedcakes. Purslane contains more Omega-3 fatty acids than any other leafy vegetable plant. Simopoulos states that Purslane has .01 mg/g of EPA. This is an extraordinary amount of EPA for land based vegetable sources. EPA is an Omega-3 fatty acid normally found mostly in fish and some algae. [3] It also contains vitamins (mainly vitamin C, and some vitamin B and carotenoids), as well as dietary minerals, such as magnesium, calcium, potassium and iron. Also present are two types of betalain alkaloid pigments, the reddish betacyanins (visible in the coloration of the stems) and the yellow betaxanthins (noticeable in the flowers and in the slight yellowish cast of the leaves). Both of these pigment types are potent antioxidants and have been found to have antimutagenic properties in laboratory studies.[4]

I got an organic herbicide last year (before the price skyrocketed) under the brand name Biosafe weed control. It contains Ammonium Nonanoate, I notice Ortho is now selling this under the name Ground Clear OMRI and it does work on poison ivy. It only kills the portion of the plant above ground that has been sprayed. Killing all the foliage a few times will kill it off over time. It seems to work best when the plant is recieving the most sun it gets during the day. Just the other day I gloved up, put on long sleeves, and manually pulled out a lot of poison ivy vines (I am very allergic). I dont spend more than 20-30 minutes manually pulling before I wash up with dish soap and cold water. I have successfully used cut stem roundup concentrate applied with a foam brush on large poison ivy vines as well, cutting a segment out first with long handle loppers and using the loppers to handle the vine. I get kind of paranoid about spraying triclopyr around trees.
