The second weed looks like chickweed. a little 2,4-D will take it out without harming the grass.

First looks like several things I'm familiar with, but the hairs on the leaves rule them out. Still, as a broadleaf, if you want rid of it in the lawn I would expect 2,4-D will take it out also.

Just remember that if these have been there more than a year, you likely have seed in the soil that will continue to come up for several years even if you take the plants out each year before they make new seed.

thank you for the reply. What product would be 2, 4-D please?

Most any herbicide listed for use on lawns should do the trick. 2,4-D is often found in a product called Weed-B-Gone and I have seen it on the label on Weed & Feed. Sometimes it is found mixed with other products, but chickweed is pretty susceptible to any broadleaf herbicide. As long as the product is labeled for use on lawns and turf grass you should be fine even if 2,4-D isn't part of it.

On the label, 2,4-D is often listed by that name, or by its full name, "amine salts of 2,4 dichlorophenoxyacetic acid". I mention the 2,4-D because it is a very old, inexpensive and effective herbicide. It will go after all broadleafed plants (ones that aren't grasses). It should not be used near tomatoes, however as they are extremely susceptible to the vapors. I have found that the foliage of ash trees is also damaged by the vapors, however at this time of year that wouldn't be a problem. I just don't dare park a sprayer in the shade in the summer or the leaves on the ash trees above will curl. If you use the label rates, you shouldn't have any problem with non-target ornamental plants or flowers, and don't apply when it is dead calm as an inversion layer can occur and the vapors and any mist from the sprayer can remain concentrated and airborne for some time. A light breeze dilutes and carries the vapors away so they won't accumulate to damage non-targeted plants.
