			 While you may know musician Jack Johnson for his mellow hits like 
			"Better Together," "Upside Down" or "Banana Pancakes," he's likely 
			less known for his home-grown Swiss chard, eggplants and sugar snap 
			peas. 
 An avid gardener at home in Hawaii, Johnson is not alone in his 
			obsession for getting his hands in the dirt. More than a third of 
			U.S. households now grow some of their own food, according to the 
			National Gardening Association, the highest level in a decade.
 
 The bottom-line bonus? Unlike some hobbies which can prove to be 
			gigantic money pits, like buying sports cars or speedboats, with 
			gardening, there is the practical return on your investment in the 
			way of a harvest of tasty tomatoes or leeks or radishes.
 
 A well-maintained food garden yields 1/2 pound of produce per square 
			foot per growing season, according to the NGA. So a 600-square-foot 
			garden, the American average on which households spend $70 per year, 
			could churn out 300 pounds of fresh produce worth about $600 
			annually, the association estimates.
 
			
			 
			  
			As a result, you could cut into some hefty grocery bills. The 
			average American household forks out $6,759 a year on food, or 12.6 
			percent of total spending, according to the Consumer Expenditure 
			Survey from the Bureau of Labor Statistics. Of that, $756 is spent 
			on fruits and vegetables, and $2,787 on the high cost of eating out.
 The harvest for Christy Comeaux, a 31-year-old nurse from New 
			Iberia, Louisiana, amounts to approximately $75 per month of fruit 
			and vegetables from various plots, trees and vines on her property, 
			from April through December.
 
 She spent $100 to set up a soil-less hydroponics gardening system, 
			but since then spends about $10 a season on seeds to get the veggies 
			growing. Her trees and vines cost about $20 each to acquire, and 
			after that have "little to no" annual maintenance costs.
 
 Among last year's haul: nectarines, oranges, strawberries, and 
			vegetables like lettuce and broccoli. Her projects for this year 
			include adding blackberries, grapes and plums to the mix. Best of 
			all, it is from her own yard and not shipped from halfway across the 
			world or subjected to possible chemicals and pesticides.
 
 For those living in big cities, growing produce is more challenging 
			but it is not impossible.
 
 Divya Sangam, a 32-year-old public relations specialist from Edison, 
			New Jersey, lives in a two bedroom apartment, but she grows some of 
			her favorite tropical herbs, like curry leaves, lime leaves, 
			lemongrass, and blue ginger, in a planter on the porch.

			She says her savings, even after paying for seeds, planters and 
			soil, amount to about $100 a year. Even better, she says her 
			homegrown herbs are more flavorful and fragrant than anything she 
			has found in supermarkets.
 As with any hobby, it is easy to spend more than you should.
 
 Jim Saulnier, 52, a financial planner in Fort Collins, Colorado, 
			grows around 30 crops a year, from spinach and onions to summer 
			squash and green beans.
 
 He is such a perfectionist that he spent almost $5,000 on an 
			automated sprinkler system to keep his garden humming. "That alone 
			increased my cost per cucumber," he says.
 
			Saulnier harvests so much produce that he has to give some of it 
			away, often to his financial planning clients.
 He advises budding green thumbs, especially in urban environments to 
			use so-called "grow bags," which are essentially big fabric 
			planters. They do not cost a lot, won't take up much space, and make 
			harvesting a snap.
 
 The benefits of gardening are more than just financial, as musician 
			Jack Johnson can attest. He is so creatively invested in the process 
			that he is featured in a new documentary on gardening and preventing 
			food waste, in conjunction with the organization Sustainable 
			America.
 
 "It's a fun thing to take on," Johnson said as he reflected with 
			pride about his success with heirloom tomatoes. "We are spending 
			less at the store, and my kids are enjoying seeing how much we can 
			grow in our own garden."
