Creating a Raised Garden Bed
If your current planting goals involve plants that require good water drainage, I am sure you know
how frustrating it is to have a yard that just won't cooperate. Another issue for many people is spending many hours bending down to tend their vegetable garden. Both of these problems can be improved — often dramatically — by creating a raised garden bed.
Some plants can handle the excess water
that comes about from being in an area that doesn't drain properly. In fact, it might just cause them
to bloom more lushly. However, other plants don't cope as well, and it will cause them to die a
gruesome, bloated death. You should always find out about the drainage required for every plant you
buy, and make sure that it won't conflict with any of the areas you are considering planting it in.
How To Test Your Soil's Drainage
In order to test how much water your designated patch of soil will retain, dig a hole approximately
ten inches deep. Fill it with water, and come back in a day when all the water had disappeared. Fill it
back up again. If the 2nd hole full of water isn't gone in 10 hours, your soil has a low saturation point.
This means that when water soaks into it, it will stick around for a long time before dissipating. This is
unacceptable for almost any plant, and you are going to have to do something to remedy it if you want your
plants to survive.

The Solution - The Raised Garden Bed
The usual method for improving drainage in your garden is to create a raised bed. This involves creating
a border for a small bed, and adding enough soil and compost to it to raise it above the rest of the
yard by at least 5 inches. You'll be amazed at how much your water drainage will be improved by this
small modification. If you're planning to build a raised bed, your prospective area is either on grass
or on dirt. For each of these situations, you should build it slightly differently.
If you want to start a raised garden in a non grassy area, you won't have much trouble. Just find some
sort of border to retain the dirt you will be adding. I've found that there is nothing that works quite
as well as a few two by fours. After you've created the wall, you must put in the proper amount soil and
steer manure. Depending on how long you plan to wait before planting, you will want to adjust the ratio to
allow for any deteriorating that may occur.
If you're trying to install a raised bed where sod already exists, you will have a slightly more difficult
time. You will need to cut the sod around the perimeter of the garden, and flip it over. This may sound
simple, but you will need something with a very sharp edge to slice the edges of the sod and get under it.
Once you have turned it all upside down, it is best to add a layer of straw to discourage the grass from
growing back up. After the layer of straw, simply add all the soil and steer manure that a normal garden
Planting in the raised garden bed
Planting your plants in your new area (i.e. the raised garden bed) shouldn't pose much difficulty. It is essentially the same process
as your usual planting session, except that it's easier on your back. Just be sure that the roots don't extent too far into the original ground
level. The whole point of creating the raised bed is to keep the roots out of the soil which saturates
easily. Having long roots that extend that far completely destroys the point.

Conclusion - The Improvements
Once you have plants in your new raised garden bed, you'll notice an almost immediate improvement. The added soil
facilitates better root development. At the same time, evaporation is prevented and decomposition is discouraged.
All of these things added together makes for an ideal environment for almost any plant to grow in. So don't be
intimidated by the thought of adjusting the very topography of your yard. It is a simple process as I'm sure
you've realized, and the long term results are worth every bit of work.
Patch From Scratch & Cottage Gardens, by Peter Cundall and Gardening Australia (DVD). This is a combination of two videos that used to be sold separately on VHS. The "Patch from Scratch" video is really, really good if you want to learn from scratch about how to grow vegetables organically. In Patch from Scratch, Peter Cundall shows you step-by-step how to start a vegetable garden, beginning with an ordinary suburban lawn. He goes through each season (some of then broken into early and late) for 18 months, describing everything in amazing detail. There is so much information in this video you could watch it 100 times and still learn more. The only real criticism of it I can think of is that it is so densely packed with information, your brain gets saturated after 10 or 15 minutes. So don't expect to take it all in in one sitting. I would recommend watching it through all the way just for an introduction, and then watch just the section for each month that you are up to, and do what he explains in that month/season.

Organic Gardening, Peter Bennett. I found this book to be very helpful. It is devoted entirely to organic methods of gardening. Almost all of the book (all of it except for about 5-10 pages) is about food plants rather than flowers or other ornamentals. The back cover states that it is the accepted major work on the subject of growing and cultivating plants in Australia and New Zealand using natural methods.
