I have a question that is puzzling me for some time now.. My wife took a clipping of a plant and put the clipping in a pot of soil.. It is a clay pot about 3" in diameter.. She filled up the pot with good soil and just let it grow.. Other than water, it was not fed anything.. After some time, the plant grew big and although I am not good at that, even I noticed the plant needed to be planted in a much larger pot.. I helped her do exactly that.. She got another large pot, put in some soil and asked me to turn the smaller pot upside down and insert it in the larger pot.. Well, when I did that I noticed that the small plant pot was ALL ROOTS with no soil at all.. My question is............ WHERE DID THE SOIL GO ???
