Barbalee--the there are two or three weeds that when the weeds are small look like daylilies . Nutsedge, the Chinese day flower, and a spiderwort weed. Nutsedge is thinner and has a sharp middle crease. Not getting it all or pulling results in more. The plant you pull leaves little "nuts" behind which gives you more than you originally had. They can be attached to each other. The other two if a piece remains in the ground they come back, too. Their roots really look like baby daylilies. After they are a few inches tall you can tell by the foliage. It is segmented and gets flowers. Your pictures look like nutsedge. The easiest way is to go a nursery and get nutsedge killer and you paint it on with a paint brush, more like an artist brush. Do not get on surrounding plants. Nutsedge is a big problem. If there are no other plants around you could pour boiling water on them. It looks like your daylilies are too close to use boiling water. I wish I had better news. May you have a safe and healthy month!
