These vegetables, herbs, and fruits will work for most people but if you’re in an area, like me, with the extreme heat you’ll want to check out planting calendars for your zone. Make sure you take time to check out the zone and understand exactly what you’re dealing with!

If you’re in Phoenix I recommend using the calendar from the Maricopa Extension Office.

If you aren’t sure what planting zone you are in the USDA has a great interactive map for you. And you can just put in your zip code and it will tell you exactly what planting zone you are in.

Beets – If your soil hasn’t consistently reached 50 degrees in March you’ll want to wait. Consider starting your seeds indoors and then transplant later. To help with germination Rodale’s suggests that you soak your seeds for a few hours before planting.
Beet Seeds to Consider: Early Wonder, Boltardy, Detroit Golden
Carrots – Carrots should be planted directly into the garden (don’t try to start them indoors). It is best to plant them about 4 weeks before the last frost. Here in Phoenix, carrots are a fall and winter crop.

Broccoli Seeds to Consider: Di Cicco, Early Purple, Waltham
Cabbage – Start your cabbage indoor about 7 weeks before your last frost.
