Those of you who've been around for a bit know that I'm a paperwhite evangelist during the holiday season. But I'm afraid I've led you all astray as to the best method for growing them.
This year I didn't have enough rocks to fill my bowl, but I did have a leftover bag of potting soil. So I used soil to fill most of the bowl, and just put a layer of rocks on top to make it pretty.
Guess what? Paperwhites like soil. They like it a lot. These are the biggest, fattest paperwhites I've ever grown. While you can certainly get by with just rocks and water, I don't believe I will ever be doing so again.
