Howzit!? Newbie from WI

Greetings from Wisconsin!

I've "accidently" started growing and don't have a clue as to what I'm doing. I tossed some seeds on the ground earlier this spring and sure as shit, I've got nine plants growing in a little cluster!

I've been reading a little about the male/female thing. I'm not sure I really understand what thats all about but I think I may be beyond the point of sexing. The plants are all about 2ft tall and the tops just started to branch off the main stems. I've got three or four sprouts coming off each main stem.

At this point I'm just going to keep letting them grow and see what happens.

Is there any risk in digging these up and replanting them somewhere where my wife won't find them? I'd prefer to keep my nuts intact but if she figures out what I've got growing in the yard, I'm done!

Any pointers would surely be appreciated.
