The top one looks like a cucumber or melon/pumpkin/squash seedling.

I've never planted those things before and this is in front yard. Any veggies I've planted are in backyard.

My "opinion" is #1 - a melon, cucumber or some kind of squash. Birds help transplant - bless their wittle bitty hearts. #2 - It's a tough flowering weed I get here too. Dang things are pretty, but their roots are distant cousins of bermuda in my opinion. They have a long tap root, right? #3 - Could be sedum...but probably not. Looks like a weed I see often in the spring out here. We have LOTS of "yard" too....and being city-transplant - these types of weeds drove me crazy the first few years I lived rural. Now, I may or may not yank them....but often watch them die a slow death in this Oklahoma heat. They usually don't last past May in our part of the state.

And if you find a good yard guy, please share!!!!!!

The top one looks like a cantaloup seedling. The bottom one maybe elm seedlngs if there is an elm tree nearby

Thanks, everyone! I'll leave Plant #1 and see what it becomes. I'll try to dig out all of Plant #2. Plant #3...as a matter of fact, I have 2 lace bark Elms! By George, I think you've got it!

Is it okay to move Plant#1 to a different part of the yard? It is in my front flower bed. I'd rather it not be in that particular bed.

You know, I like to buy melons for the kids in Summer. Someone may have spit a seed or two in the direction of my flower bed, lol!

Well, I think plant #1 is probably pumpkin. I clean out pumpkins every Fall and put Pansies in them. I forgot about that. I bet I missed a seed or two!
