There are many great benefits to growing plants in
raised beds. One of the biggest benefits is the ability to harvest more
produce from the same space. Raised bed gardens can actually double or
even triple the amount of produce harvested from the space! This is due
to the fact that the square footage needed for pathways is reduced
considerably, and more space can be devoted to the plants.
Another
great benefit to growing in raised beds is the fact that you can
improve your soil conditions more readily, and you can even grow plants
in areas with extremely inhospitable soil. If your garden is typically
very sandy or you have a lot of clay, it can be difficult to grow much
in it. But if you create a raised bed, you can simply put your own
purchased or created soil mix into the frame and grow your plants in
that.
Weeds are also much less of a problem in the typical raised
bed. Because the soil is confined, it's much easier to spot any weeds
that do pop up, and the weed seeds in the existing soil are buried
under far too much soil to sprout in most cases.
The frames can
also be built with a bottom and placed on tables so handicapped and
elderly people can reach their plants to care for them more easily.
This is a major benefit for people who otherwise wouldn't be able to
properly care for a garden.
This type of gardening was made
popular by Mel Bartholomew in his book and television series called
Square Foot Gardening. He developed a system that requires about 80%
less space than traditional types of gardening.
Instead of being
just a standard raised bed, the bed is divided into sections that house
plants of various sizes. It uses special soil mix that is free of weeds
and is ideal for growing almost any kind of plants. It uses less water,
is all organic, and uses far fewer seeds than traditional gardening.
His system claims you can produce 5 times more in the same space of a
traditional garden.
The system divides each square foot into a
grid, based on what type of plants you wish to grow in that section. If
you want to grow a large plant like broccoli or cabbage, it would take
one entire square foot, so that section wouldn't be divided at all. If
you want to grow radishes, you might section that square foot into
sixteen separate spaces, each one housing a single radish!
Other
similar systems have been brought out. Cubed Foot Gardening is very
similar to Square Foot Gardening. The creator of this particular system
is Christopher O. Bird, and he credits Mel Bartholomew for creating the
original system. Bartholomew even gave the system an endorsement!
You
don't have to use a grid system at all. You can use a raised bed to
plant a wildflower garden or an herb garden with no definable
organization. This works just fine. You don't have to restrict yourself
to a grid-based system if you don't want to. Raised beds are very
flexible!
