Consider the tomato; most people think it's a safe bet for a high-yield return - but which variety? Heirloom tomatoes typically cost $5 or more a pound at farmers' markets. You can beat that price by growing Cherokee Purples from seed at a net cost of only 80 cents per pound. If you plant purchased seedlings, the cost will go up to about $1 a pound -- and that's including the cost of water and fertilizer. This is the kind of invaluable data and advice you can trust High-Value Veggies to provide.Whether you're interested in growing tomatoes, pumpkins, cabbage, corn, or anything else, it's wise to consider the invisible dollar signs sown along the way. The relative return on investment for each veggie in High-Value Veggies is calculated based on dollar value generated for each square foot planted. You don't need to be a math whiz to plan your next vegetable garden. Bartholomew has done the math for you, and he has cost-effective answers.
