Often called raised bed gardening, it is a method that includes no-dig, no-till, lasagna, straw bale, and square foot gardening.
A raised vegetable garden bed can be as high as a kite, as low as your toe and as many layers as you want to stack on.
Raised vegetable gardens are loved by gardeners' backs, because there is less stooping and digging.
So, phooey to all that seriously wicked waste of energy.
Now let's get into the perennial argument over which raised bed gardening method is best.
What constitutes a raised garden? Anything such as a pile of dirt or a mound of no-dig materials (see Lasagna Gardening.) But the real McCoy has borders built around it.
Some ideas to get you thinking
Wood looks good. Scrounge or buy what you need. Kitsets are available, make your own or have a handyperson build them for you.
There is some debate whether treated timber leaches preservatives into soil and plants, so avoid it if you're not 100% sure.
Timber (or lumber) such as macrocarpa, totara, jarra, cedar and redwood will last for many years untreated... 7 years and some. Some woods are softer and will breakdown quickly, but you can drench the insides of your garden boxes with safe and cheap linseed oil to help preserve them longer.
Have you got access to bricks? Concrete blocks? Rocks? What about the beautiful edgings available from garden centers or old logs on beaches?
And so on... the point being, is that there are hundreds of ways to make a raised vegetable garden, and there's no digging involved and they are built up from the ground, whether they are in boxes, tires, crates, or just natural mounds.

Thanks to Les Boucher from Australia, who has provided the following photos of building a no-dig garden with a raised vegetable garden bed (See Les' comments below):Step 1. Lay out your garden area. Leave the grass it will die, or cut it if you wish. The garden beds can be any height.
I've previously built ones for community groups of about 1m (3ft) high to allow for wheelchair access. It's a matter of layering to get things to the height you want.
Step 2. Lay out old cardboard. Try your local supermarket for this... recycling again...love it...
Step 3. Wet your newspaper before you spread it out it will stick together when you overlap it.
Step 4. Spread WET newspaper OVER cardboard making sure that it overlaps by about a quarter to one third of its size.
By doing it this way you are cutting out the sunlight and the grass will die and it, as well as the cardboard and paper, will all rot back and feed Mother Earth.
Step 5. Next comes a layer of Lucerne Hay (more food as it breaks down).
Step 6. A thin layer of Manure (in this case "Moo Poo") is then laid out...
Step 7. Finally this is all covered with a layer of straw (I use Pea Straw as it adds more nutrient as it breaks down) and it also works as a mulch for your plants keeping them warm in the winter and cool in the summer.
Step 8. From here it is just a matter of making a small hole in the top layer of straw and adding a handful of potting mix or compost and planting into it.
You can see the results of this one that I prepared earlier.
I hope that this inspires you to build your own raised vegetable garden and to get out into your yard and smell the roses (or cabbages).
Here's Les, and his comments:
"Since building these garden beds, I have gone on to share this idea with others, including building eight beds 4m x 2m (13ft x 6½ft) for a men's shed complex near where I live. These are about 1m (3ft) high to allow access by wheelchair bound people as well as those able bodied people who have bad backs." Les Boucher
