I am an American who is hoping to move to the Yucatan in the next few years. I have been an organic gardener my entire adult life.
I am curious about the vegetable growing season in the area. I have vacationed down there at the end of August, and I know the vegetables that I had in my garden back home in August probably would not have survived the temps in Mexico at that time.
When do you typically plant and harvest?

This is a ''garden calendar'', and the link is to USDA zone 11B, sourthernmost Florida. The climate is similar to Yucatan, with the caveat that it is HOTTER hear, and the late dry season (now through May) is frequently accompanied by strong, dry winds, which make things difficult for plants. As a rule of thumb, the calendar Spring (March-May) is NOT a good time to plant, as the weather is just too hot/dry for seedlings (or for cool weather crops, like peas, lettuce, etc.). You might talk to the folks at Colectivo Milpa (they have a Facebook page), for tips on organic gardening in Yucatan. At least one of the guys there speaks English fluently, if language is an issue.
As others have said, the coast presents special problems, but most serious gardeners here need to invest in sun protection and irrigation of some sort. And, of course, soil is another issue -- again, many gardeners use some sort of raised bed system, relying heavily on compost to create a good, organic-rich soil.
