What Airbnb has done for vacationers looking for a room to rent, Alfrea hopes to do for those looking to grow their own food.

The New Jersey-based start-up launched Alfrea.com Friday to connect those wanting to garden with people who have some extra planting space to offer.

And if growers wind up with more tomatoes and zucchini than they can make sauce and bread with, Alfrea.com will help them sell that surplus.

The site also provides matchmaking with gardening experts, such as people who will water and weed for $20 an hour, and others offering canning services for $15 an hour.

Alfrea is cofounded by David Wagstaff, a financial analyst and consultant with a personal interest in environmental issues, and Patrick Mullin, who is certified in nutrition and has experience in digital marketing.
