I have been reading the posts as this fall will be my first garden. It is still scorching here in the Phoenix area and I would appreciate some guidence on when to start planting. I will start with only 1 or 2 beds and have some questions about placement. My house faces the brutal west so my initial gardens will be along north and south walls in backyard. A local expert said to plant where there is full sun. Does that make sense for this type of garden? Also I want to have tomatoes, eggplant, peppers and herbs. Broccoli and Cauliflower would also be great, but I read the recent post about the aphids, they are very bad here. Any tips on when should I start my seed? (I just noticed the recent posts suggested sowing in ground rather than starting indoors)

thanks
