Well, you didn't say what city since this is an Arizona forum. But I suppose 9 in 10 chance it is the Phoenix area.

I attached a 25 page PDF link to my gardening guru that I keep up with. Hope it helps. Also here are some cheat sheets...they are all fairly similar except for the two gardening guides from the Coop Exchange. With our year round gardening and lack of winter, brutal summer it is definitely a different schedule than you are used to.

F_N:
This is a great list. Thanks.
I've lived here a long time, but never made a serious attempt to grow anything. My lack of knowledge is overwhelming.
This website is great, I've already picked up a lot. Thanks again for your contributions!

The East Valley Gardeners Club (Mesa) are having a garden sale of vegetables and herbs plants/seeds Sat. March 8th, 20149AM-1PM at the Mesa Community College Rose Garden, Phase 1 (worth going there just to walk around their rose garden and arborium). They make a great handout that I am staring at right now, but a sh**ty job advertising the sale on their web site.
