Gardening doesn't get the same media play as the culinary professions. While garden shows and magazines are suffering food related media grows. I think we are going to see and are seeing a melding of the two arts as we head into the future. The biggest trend I can see coming down the pike is people growing and then preparing their own food. Not so much as a survival technique but as an artisan revival. Found a hydroponic shop that sells gardening supplies, wine making supplies, and beer making supplies. The gardening supplies sell during spring while the beer and wine making supplies sell during winter. I expect to see more hybrid stores like this in the future. You could come up with some fun fall and winter workshops with these subjects.
