Hello all, 2 weeks ago I set up my elevated raised bed(2ft off ground) with an organic potting mix from Walmart and some of my own kitchen scrap and grass clipping (well composted) compost. Today I noticed these little plants growing throughout the bed, the entire stalk comes out easily with a tug but what are they, and where did they come from? Thanks in advance

Perhaps tomatoes (from kitchen scrap).

Looks more like a cucurbit to me (melon, squash.) Did you compost some scraps from something like that? ... or are you asking about the tiny things?

The tiny plants look like tomatoes. I am assuming farmerbob919 planted the cucumber/melon/squash looking things.

looks like tomatoes seedling,
But pepper could also be another possibility, soon after true leaves appear it will be clear

Thanks for the replies. I used apple, bananas/peels and orange peels, tomatoes scraps in the compost. But its been sitting for over a years mixed with mostly grass clippings so it was pretty much black dirt before I mixed it with potting mix...Is there not any chance the store bought potting mix had any seeds in it?

My thought is it's your tomatoes since the seeds can survive composting. I've gone through it.
