ROCKY MOUNTAIN STATES
Planting and harvest dates vary according to location. A good rule of thumb is to sow warm-season vegetables (chiles, corn, cucumbers, edamame, melons, squash, tomatoes, zucchini) indoors from seed about six weeks before average date of last frost, and plant seedlings outside only after average date of last frost. 

Your local county agricultural extension office can give you dates specific to your area, as can most local nurseries.
