I have noticed that in most of the pictures of the chix n hens they are potted with little rocks all around them, is that better for their growth than just soil? i'm new to these types of plants but am in love with them and am trying to learn all i can about them and what helps them grow the most. i've learned how to prograte them, witch is not as easy as it shows i'm lucky if 3 out of 15 take unless i'm doing it wrong ofcourse. last summer 1 of my chix n hens grew up to a foot and a half tall i had NEVER seen one grow like that before it was pretty awsome but ofcourse it died. If anyone has suggestions or ideas i'd love to hear them. Thank you. brandi6262
