Not only do you need to wory about others stumbling across your crop...but animals, too.

Since you'll likely need to add nutes and water, will anyone see you going back and forth to the crop, during the summer? (only takes once for a face to be matched to your crop, or a curious neighbor wondering where you keep going)

If unsure about how stealthy your chosen spot is...likely you shouldn't grow there.

Any other kids in the area that would steal the plants?
