Notes:

this is a tenacious weed taking over my sedum bed. It is slightly fleshy leaved, has never flowered and spreads by shallow runners. The leaves are arrowhead shaped and I have tried to hand weed it rather than use herbicide because I’m afraid I will kill the sedums too. Winter didn’t slow its spread one bit! Help!

    Indicator weeds are weeds that are most often found in specific soil types or conditions. Your weed, sheep sorrel, is one that indicates acid soil conditions. Sedum can tolerate soil ph from acidic to alkaline. It is not a guick fix but try liming. I have seen sheep sorrel decline in junipers after liming one year earlier. Preemergent herbicides would probably reduce growth from seed but sheep sorrel is a perennial weed so expect regrowth from established plants. I can’t think of any post emergent that wouldn’t injure the sedum in your effort to control the sorrel.

    It looks like sorrel or sheep sorrel (Rumex) If that’s the case, the best thing you could put on it would be a little raspberry vinaigrette, then eat it.

    Actually it’s a winter weed, so that may explain the growth in the winter. But you may need to use some elbow grease to get it out of your sedum bed, because the usual broad leaf weed control will certainly kill the sedum.

    This is sheep sorrel (Rumex acetosella). You may not want to hear this, but it is actually an edible plant (in moderation). Yes, it can be obnoxious and I also hand-weed it from my flower and vegetable beds.

    maybe I’ll put some chicken wire around the bed and turn a rabbit loose in there! If it’s tasty like you say he should gobble it right up!

    It is definetely Sheep sorrel weed. It is a perennial weed favoured by impoverished acidic soils. Reduce it on your bed by improving soil fertility such as application of organic manures and liming. This will however take some time because of the weed’s mode of propagation. It reproduces both sexually and asexually. The latter makes it very difficult to control because unlike most plants, any small piece is able to germinate regardless as to whether it contains a node or not. All the best.
