My late husband, Duane, and I wrote vegetable garden books, including The Postage Stamp Garden Book; California Vegetable Patch; Small Space, Big Yields; The Postage Stamp Kitchen Garden Book; The Vegetable Factory, The Vegetable Gardeners Sourcebook, and more. Duane, in 1976, pioneered the French Intensive Biodynamic small space garden era with The Postage Stamp Garden book. Over the years our garden books have one thing in common, small gardens using the French Intensive Biodynamic Gardening method. Using intensive methods, you can, for instance, grow as many carrots in 1 square foot as you can in a 12-foot row in a conventional garden. Properly handled, a 24-square-foot bed (5 by 5 feet) will produce a minimum of 200 pounds of vegetables. The smallest beds I recommend are 4 x 4 feet, the largest, 10 by 10 feet (although they can be bigger). I also recommend raised bed gardens. Regardless of which size you choose, your postage stamp garden will produce a tremendous amount of vegetables, and after the initial preparation, require little extra work, even less if you add a drip system to do the watering.
Where to Locate Your Garden
How to Design Your Small Space Intensive Garden
The following are planning rules that will help you obtain maximum results.

Consider Raised Beds
There is something that sparks the imagination with these beds. They’re neat, clean, and easy to handle. You can walk all the way around them, you can thin the plants without getting dirty, and you can have as many as you want in any arrangement you like. If you’re handy with building things all you have to do is measure out the size you want, such as 4-by-4-foot space, prepare the soil, then frame the space with 2-by-4 inch planks and nail the corners together. If you prefer something that is easy to construct and looks great, check into pre-made raised beds. These are all-in-one complete kits with easy to assemble instructions. There are a number of sizes to choose from at EarthEasy.com.

Getting Your Soil Ready
For any size garden bed you choose I highly recommend buying a rototiller. In subsequent years the soil will be loose, and you can spade it up if you like. In any case, here is the procedure:
For sandy soils, turn compost into your bed until you have 1/3 to ½ compost, the rest original soil. For in-between soils, just estimate how much you’ll need of one thing or another in order to end up with a mixture that contains at least 1/3 compost that is loose and fairly fine and that has good air space and is easy to work. You can purchase sand from most building supply or garden centers.
Most garden centers sell an organic fertilizer that contains these ingredients, making the job easier. Just buy this fertilizer and spread it in your garden.
How Far Apart to Set Plants
When planting vegetables in an intensive postage stamp garden, space the plants a little closer than generally recommended on seed packets or on instructions for seedlings. Corn, for instance, does quite well planted 8 inches apart as opposed to the 12 inches usually recommended for conventional gardens.

It isn’t necessary to buy compact plants for small space gardens, unless you want to. Normal varieties grow just fine. However, if you want to grow melons of any kind try using space-saving varieties.
