Before planning your raised garden two decisions should be made: (1)
Where to locate it and (2) how big you want it to be.

Location has to do with making sure that the garden will have the
maximum sun and that it is fairly level and near a source of water.

Selecting your Raised Garden size and location.

Before planning your raised garden two decisions should be made: (1)
Where to locate it and (2) how big you want it to
be.

Location has to do with making sure that the garden will have the
maximum sun and that it is fairly level and near a
source of water. One additional thought about location; and that is
the option of placing the garden on a paved surface or
an inner city roof top . . . more.

Size has to do with the alloted space available and what you intend to
grow. Sizes ranging from 2 ft. by 2 ft. square may
be preferable for some plants because they have a tendency to
overwhelm the rest of the items when planted in a larger
garden. This size might be a good choice for growing something like
squash which often produce very large leaves and
would excessively shade other plants. Some of these plants grow into
vines and will expand well beyond the raised
garden itself.

An increasingly popular size is a 4 ft. by 4 ft. garden because of
their versatility. For instance, several 4 x 4's may be
easier to manage than a full 4 ft. by 8 ft. garden. The 4 x 4 lends
itself very nicely to being able to rotate your crops from
year to year by switching your produce from one garden to another each
season. This prevents the nutrients consumed
by one type of vegetable from continuing to drain the soil year after
year. As an example, this size of garden is ideal for
cultivation of tomato plants since four plants can be nicely
accommodated by this size assuring plenty of room to grow.

The ideal maximum size garden is the very popular 8 ft. by 4 ft.
garden. This size garden should be used to plant
vegetable that will take less space for each plant such as lettuce and
other items one would normally plant in rows. The
tendency is to over crowd the larger gardens so care should be taken
during your planning. They are also excellent for
fall and winter gardening when very large items such as cabbage and
other hearty winter vegetables are to be grown
when crowding is not an issue. Cabbage, broccoli and cauliflower
spread out to a great extent and this larger size garden
will accommodate them.

The depth of a garden is also a consideration. If you plan to grow
herbs, then a garden that will accommodate soil that is
6 inches deep is really all that is needed. Typically, gardens used
for growing most vegetables requires a soil depth of
close to one foot.

Of course if you are an avid gardener and have the space, having
several sizes of gardens can be very rewarding and lend
more options to your gardening experience.
