help w/ clay soil and penstemons, crocosmia, etc.
Hi folks! I'm a beginning gardener. We started our garden from scratch in Dec '09. It's clay alkaline soil. We're zone 9/10, SW 18. inland socal.
Last year I had pretty good luck with penstemons all through the summer (which is pretty dry here, but I give them some garden water) but then in the winter, I think they rotted.
Is this just an issue of me not amending the ground enough to get better drainage? I know my drainage is poor, but I do try to amend with pumice and compost and "amend" and that sort of thing. Maybe plant even higher, and perhaps put rocks around the higher area to try to get the soil to stay in a berm to help them drain better?
I really like them, so I'd like to figure out how to get them to work better for me.
Also, all these crocosmia,... why are they looking sad? :( I amended the soil so much!
