Ha ha - when I did an internet search, I found the answer inside our own web site:
http://garden.org/ideas/view/f...
Not sure if this is where I read it or not, but you may want to check with flaflwrgrl to find out where she got her information. Sorry, I also don't know how to make the above information be a direct link, even though I know it is quite simple...
Edit: Oh, stupidhead (me), it just IS a link, nothing special for me to do.
