This link will open to a pdf chart. It is a locally created "Planting and Harvest Calendar" for the Phoenix Area (low desert) that comes highly recommended.
We are slightly cooler than Central Phoenix so it is a good general guide.
To summarize, now is planting time for:
Beans (almost past time),
Peppers (will blend their 'hot-ness' if close to each other, so space them out as much as is practical for you if you want sweet peppers to stay sweet),
Squash (all of them: zucchini, pumpkin,..),
Eggplant,
Sweet Potatoes, (wash the kind you like to buy (it has sprouting inhibitor chemicals on it) and leave it on the counter until it sprouts; then cut a big chunk including the sprouted portion and plant it. I hear it grows like a weed here.)
Sunflowers, and
Melons (all of them: cantaloupe, watermelon,..)
If anyone would like to do an herb garden, leave a comment below. I would love to split 6 packs of plants. I am interested in doing Parsley, Cilantro, Basil, Marjoram, and others with very little convincing. :)
