Cool, I will have to try my Freesias in the ground, then. Love, love, love them.
My soil up here is really variable - clay, to sand. I think the previous owners added a lot of the sand, they sure put down a ton of gravel! I've begun amending a lot of it with horse manure, at least in beds I know won't be used immediately. It's hard, too - so many of the desert plants prefer no amendments, so mixing them into my beds is tough.
