Mucho Help Wanted

So i was out in my garden, and stumbled upon about four pot plants. After thinking about it, i decided i want to harvest it. The dude that lived in my house before, was a total freak and probablly planted them. Their punny little plants, but they have potential. If there is anybody that can help me either telling me what to do first, or that i shouldnt both, i'd like an opinion. I've got no clue where to begin, and I admit i know barely anything about it, but i'm deff willing/wanting to learn. So any master-pot growers out there, help. Thanks

You may not need to do anything if they're in the ground and are fairly developed. How tall are they? How many nodes do they have? How many hours of sunlight do they get a day?

If they're over 10" tall it may be time to start fertilizing.

If you could post some pictures it could help immensely.

Let them grow!!!!!!!!!!!
We love pic's, got some?
