Growing your own vegetables is both fun and rewarding. All you
really need to get started is some decent soil and a few plants. But to be a
really successful vegetable gardener — and to do it organically — you'll need
to understand what it takes to keep your plants healthy and vigorous. Here are
the basics.
"Feed
the soil" is like a mantra for organic gardeners, and with good reason. In
conventional chemical agriculture, crop plants are indeed "fed"
directly using synthetic fertilizers.
When
taken to extremes, this kind of chemical force-feeding can gradually impoverish
the soil. And turn it from a rich entity teeming with microorganisms insects
and other life forms, into an inert growing medium that exists mainly to anchor
the plants' roots, and that provides little or no nutrition in its own right.
Although various fertilizers and mineral nutrients (agricultural lime, rock phosphate,
greensand, etc.) should be added periodically to the organic garden, by far the
most useful substance for building and maintaining a healthy, well-balanced
soil is organic matter. You can add organic matter to your soil many different
ways, such as compost, shredded leaves, animal manures or cover crops.
Organic matter improves the fertility, the structure and the
tilth of all kinds of soils. In particular, organic matter provides a
continuous source of nitrogen and other nutrients that plants need to grow. It
also provides a rich food source for soil microbes. As organisms in the soil
carry out the processes of decay and decomposition, they make these nutrients
available to plants. For more on this subject, read Building
Healthy Soil.
Make Efficient
Use of Space
The
location of your garden (the amount of sunlight it receives, proximity to a
source of water, and protection from frost and wind) is important. Yet just as
crucial for growing vegetables is making the most of your garden space.
Lots of
people dream of having a huge vegetable garden, a sprawling site that will be
big enough to grow everything they want, including space-hungry crops, such as
corn, dried beans, pumpkins and winter squash, melons, cucumbers and
watermelons. If you have the room and, even more importantly, the time and
energy needed to grow a huge garden well, go for it. But vegetable gardens that
make efficient use of growing space are much easier to care for, whether you're
talking about a few containers on the patio or a 50-by-100-foot plot in the
backyard. Raised beds are a good choice for beginners because they make the
garden more manageable.
The first way to maximize space in the garden is to convert
from traditional row planting to 3- or 4-foot-wide raised beds. Single rows of
crops, while they might be efficient on farms that use large machines for
planting, cultivating, and harvesting, are often not the best way to go in the
backyard vegetable garden. In a home-sized garden, the fewer rows you have, the
fewer paths between rows you will need, and the more square footage you will
have available for growing crops.
Less
effort. When
vegetables are planted intensively they shade and cool the ground below and
require less watering, less weeding, less mulching — in other words, less
drudgery for the gardener.
Less
soil compaction. The more
access you have between rows or beds, the more you and others will be
compacting the soil by walking in them. By increasing the width of the growing
beds and reducing the number of paths, you will have more growing area that you
won't be walking on, and this untrammeled soil will be fluffier and better for
plants' roots.
Grow Up, Not Out
Next to intensive planting, trellising represents
the most efficient way to use space in the garden. People who have tiny gardens
will want to grow as many crops as possible on vertical supports, and gardeners
who have a lot of space will still need to lend physical support to some of
their vegetables, such as climbing varieties of peas and pole beans. Other
vegetables that are commonly trellised include vining crops, such as cucumbers
and tomatoes.
The fence surrounding your garden may well do double-duty as a
trellis, so long as the crops grown on the fence can be rotated in different
years. Other kinds of vegetable supports are generally constructed from either wood
or metal. However, no matter which design or materials you use, be sure to have
your trellis up and in place well before the plants require its support —
preferably even before you plant the crop. With some vegetables, such as
tomatoes or melons, you may also have to tie the plants gently to the support,
or carefully weave them through the trellis as they grow.
Keep Crops Moving
Crop
rotation within the vegetable garden means planting the same crop in the same
place only once every three years. This policy ensures that the same garden
vegetables will not deplete the same nutrients year after year. It can also
help foil any insect pests or disease pathogens that might be lurking in the
soil after the crop is harvested.
To use a
three-year crop rotation system, make a plan of the garden on paper during each
growing season, showing the location of all crops. If, like most people, you
grow a lot of different vegetables, these garden plans are invaluable, because
it can be difficult to remember exactly what you were growing where even last
season, much less two years ago. Saving garden plans for the past two or three
years means that you don't have to rely on memory alone.
A Continuous Harvest
Planting crops in succession is yet another way to maximize growing area
in the garden. All too often, though, gardeners will prepare their seedbeds and
plant or transplant all their crops on only one or two days in the spring,
usually after the last frost date for their location.
While
there is nothing wrong with planting a garden this way, wouldn't it be easier
to plant a few seeds or transplants at a time, throughout the course of the
whole growing season, rather than facing the herculean task of "getting in
the garden" all at one time?
After
all, a job almost always becomes easier the more you divide it up. Plan to
plant something new in the garden almost every week of the season, from the
first cold-hardy greens and peas in late winter or early spring, to heat-loving
transplants such as tomatoes, peppers and eggplant once the weather becomes
warm and settled.
Then
start all over again, sowing frost-hardy crops from midsummer through mid-fall,
depending on your climate. Keep cleaning out beds as you harvest crops to make
room for new vegetables that will take their place. You can even interplant
crops that grow quickly (radishes) alongside other vegetables that require a
long season (carrots or parsnips), sowing their seeds together. This makes
thinning out the bed easier later on, since you will have already harvested the
quick-growing crop and given the long-season vegetables that remain some
much-needed elbow room.
Another
benefit of succession planting, of course, is that your harvest season lasts
longer for every crop. This means that, instead of getting buried in snap beans
or summer squash as your plants mature all at once, you can stagger plantings
to ensure a steady, but more manageable supply of fresh vegetables.
Keep Good
Records
Finally,
we end up where we started — with the realization that, although vegetable gardening
can be rewarding even for beginners, there is an art to doing it well. There is
also a mountain of good information and advice from other gardeners available
to you. Yet one of the most important ways of improving your garden from year
to year is to pay close attention to how plants grow, and note your successes
and failures in a garden notebook or journal.
Just as
drawing a garden plan each year helps you remember where things were growing,
taking notes can help you avoid making the same mistakes again, or ensure that
your good results can be reproduced in future years. For instance, write down
all the names of different vegetable varieties, and compare them from year to
year, so you will know which ones have done well in your garden.
Many
people keep a book in their car to record when they change their oil and
perform other routine maintenance. In the same way, get in the habit of jotting
it down whenever you apply organic matter or fertilizer to the garden, or the
dates on which you plant or begin to harvest a crop.
Over
time this kind of careful observation and record-keeping will probably teach
you more about growing vegetables than any single book or authority. That’s
because the notes you make will be based on your own personal experience and observations,
and will reflect what works best for you in the unique conditions of your own
garden. As in so many other pursuits, so it is in the art of vegetable
gardening: practice does make perfect.
