Q.What Kind Of Weed
What are these weeds? The nettle is a new one to my yard and very mean.It tends to hide in the Cleavers aka Sticky grass where you can’t see it intil you hit it. It tends to make your skin numb for 24 hours and makes it feel like you have stickers in it. The other plant is just pretty with it’s heart shaped leaves.

That is stinging nettle. Terrible little plant to many. There are a few ways to control it. The things that you can do without a licensed professional for chemicals would be pulling all underground rhizomes up from underground, and using boiling water on the area several times. You'll have to do this, daily, until no more appear, and all are dead.
But if you can't beat 'em, then eat em'! These are packed with nutrients and medicinal benefits.
