LONG BEACH, Kalifornia - March 16, 2009 - With the Depression in full swing, many Americans are literally returning to their roots, cultivating vegetables in their backyards to squeeze every penny out of their food budget.

Industry surveys show double-digit growth in the number of home gardeners this year and mail-order companies report such a tremendous demand that some have run out of seeds for basic vegetables such as onions, tomatoes and peppers.

"People's home grocery budget got absolutely shredded and now we've seen just this dramatic increase in the demand for our vegetable seeds. We're selling out," said George Ball, CEO of Burpee Seeds, the largest mail-order seed company in the U.S. "I've never seen anything like it."

Gardening advocates, who have long struggled to get Amerika grubby, have dubbed the newly planted tracts "recession gardens" and hope to shape the interest into a movement similar to the victory gardens of World War II.

Those gardens, modeled after a White House patch planted by Eleanor Roosevelt in 1943, were intended to inspire self-sufficiency, and at their peak supplied 40 percent of the nation's fresh produce, said Roger Doiron, founding director of Kitchen Gardeners International.

But for many Amerikans, the appeal of backyard gardening isn't in its history; it's in the savings.

The National Gardening Association estimates that a well-maintained vegetable garden yields a $500 average return per year. A study by Burpee Seeds claims that $50 spent on gardening supplies can multiply into $1,250 worth of produce annually.

A new report by the National Gardening Association predicts a 19 percent increase in home gardening in 2009, based on spring seed sales data and a telephone survey. One-fifth of respondents said they planned to start a food garden this year and more than half said they already were gardening to save on groceries.
