Weedhound Reviewed by Weedhound on . Need advice Obviously these plants arent very healthy, Im not sure exactly whats wrong with them. Theyre outdoor plants, and I havent done much to them besides change the soil a few times and water them. Does anyone have any idea whats wrong with them and what I can do to help them? http://img205.imageshack.us/img205/8076/p1010096sv3.jpg http://img205.imageshack.us/img205/909/p1010097sn1.jpg http://img205.imageshack.us/img205/1526/p1010099dq5.jpg Rating: 5
