I'm noticing a small fast growing & reproducing plant that generally starts out in brick type sidewalks and along driveways. its low growing so it stays under the mower. it also chokes out existing blue & K31 grass. What can I spray on it that will not kill the normal grasses? Also noticed seeds are sticky. if soil is damp you can grab it at its core & generally pull the root. please see attached pics. Thank you.
I can’t be 100% sure from your photos, but the plant appears to be one of the thymes. Is there an herbal fragrance to the plant when you crush the leaves?
Here is our information page on thyme as an herb. http://extension.umd.edu/hgic/herbs-thyme
We list creeping thyme as a low growing groundcover for those that want to reduce the turf in their landscape. http://extension.umd.edu/hgic/plants/groundcover-list Creeping thyme is a good groundcover planted between stepping stones along a walkway. Mowing is typically not required to keep it under control and it smells good when stepped on.
However, if this really is thyme and you want to keep it from out competing your turf, manual removal is the best option. Thyme is a woody evergreen plant and in most situations, desirable. We are not aware of any herbicides that are labeled for controlling thyme and it might be difficult to control chemically because of its woody nature.
Thyme thrives in well-drained sandy soil which might be what you have in Calvert County. Consider replanting it in a sunny place where you can keep it under control like next to a sidewalk or in a container.
Per your suggestion tested to see if its like thyme, no smell. Took additional pics with ruler for scale.
We think this looks like prostrate spurge or possibly common lespedeza.
If it is spurge, when you break a branch there would be a white milky ooze.
Please look at these possibilities in our weed gallery which can be found here:
Click on the plant names to read more. Both of these are broadleaf weeds so if there are too many to pull you could spot treat with a broadleaf weed killer labeled safe for lawns. (See the highlighted "postemergent herbicide")
Must be spurge, when you break a branch there is a white milky ooze. will try the broad leaf weed killer, Thank you
