Whether you purchase a kit or build your own,
there are a few things to consider when creating a raised bed
garden.
Locate the garden in a sunny area if possible. Most plants require
at least six hours of sun, and vegetables like tomatoes, peppers and
melons produce best with a full day of sunlight.
Select a long-lasting material such as interlocking block,
fieldstone, plastic lumber or naturally long-lasting wood like
cedar. The material selected will influence the shape and size of
your garden. Some materials allow for curved beds while others are
limited to squares, rectangles, and other angular shapes.
Design your raised bed to fit your space and your needs. A three- or
four-feet width makes it easy to reach all parts of the garden for
planting, weeding, and harvesting. Raising your planting bed at
least eight to twelve inches improves drainage and provides an
adequate space for most plants to root and grow. If you want to
minimize bending, go higher. Add benches to increase your gardening
comfort and ease.
Roughen or loosen the existing soil surface if your bed is built on
compact, slow-draining soil. This will allow water to readily move
from the raised bed into the soil below. Cover the bottom of the bed
with newspaper or cardboard, if needed, to suffocate existing weeds
and grass.
Line the bottom of your raised bed with hardware cloth to reduce the
risk of animals burrowing into your garden. Lay the hardware cloth
over the ground and bend it up along the inside of the raised bed
walls.
Fill the bed with a quality growing mix that is well drained but
also able to retain moisture and nutrients. This may be a mixture of
quality topsoil and compost, a high-quality potting mix, or a
planting mix designed specifically for raised bed gardens.
Grow any plants that you normally would grow in ground. Just make
sure the plants are suited to the growing conditions – sunlight,
heat, and wind – in your area. Since the soil mix and drainage is
ideal in a raised garden, you will be able to grow more plants per
square foot. Just be sure to leave sufficient room for plants to
reach their mature size.

Keep your plants healthy and productive with proper
watering. This is critical for growing any garden, but even more
crucial in a fast draining raised bed. The simple act of raising the
garden height increases drainage, and a raised bed filled with
planting mix means more frequent watering. Consider using drip
irrigation or soaker hoses for watering ease. Always water
thoroughly when the top inch of soil is dry.
Add some mulch to help reduce watering and the need
for other garden maintenance. Spread a layer of evergreen needles,
pine straw, shredded leaves, or other organic matter over the soil
surface. This helps conserve moisture, suppresses weeds and adds
nutrients and organic matter to the soil as it decomposes. You’ll
spend less time watering and weeding throughout the season.
Add an organic fertilizer at planting if your planting mix does not
already contain one. Apply again mid-season if the plants need a
nutrient boost. Always follow the label directions on the fertilizer
container.
The time and effort invested in creating raised beds will be
returned many times over with years of healthy and productive
gardens.
