When Karin Kuglin's garden is growing, her grocery list gets smaller.
"I didn't buy anything for salads for a month and a half," she brags.
Pennsylvania seed company Amish Heirloom Seeds is doing five times more business than usual.
"I have things I've always carried but nobody every bought them before," says Lis Von Saunder. "This year they want everything."
Gardening can also be a cheaper form of entertainment that keeps giving back.
"You don't have to go to the store every time you need a tomato or basil for your salad or marinara sauce. You have it out in the garden," says Kelsey London of Cristini's Flowers.
Money saving estimates vary, but one seed company study says $50 in gardening supplies can yield $600 to $1,200 worth of food.
