Growing your own vegetables organically has many benefits. The
most obvious is that you avoid using pesticides that are harmful to
us and the environment. Organic gardeners prefer to use natural and
organic materials and methods, rather than synthetic chemicals that
may be detrimental to our health or environment.
It's Not about Size
You don't need a large piece of property to grow your own
vegetables. Even if your piece of paradise is a small apartment
balcony or deck, you can enjoy fresh produce by growing veggies in
containers. For example, salad greens can do very well in a window
box. There are many varieties of vegetables bred especially for
containers and small space gardens. If you don't have any space at
all to garden in, many of our cities and municipalities offer
residents allotment plots for a small fee or even for free.
Wherever you garden, remember that for a successful harvest, most
vegetables need to be planted in full sun.
Getting and Keeping Good Soil
Poor soil conditions are a major reason that plants don't
thrive. Most vegetables prefer a "˜loamy' soil that is rich in
organic material and that doesn't drain too quickly. Wise gardeners
amend their soil with decomposed organic matter (compost) such as
kitchen scraps, manure, leaves, grass clippings or straw. Compost
improves the structure of the soil, aids in necessary microbial
activity, attracts beneficial earthworms, and retains nutrients
that are slowly released throughout the growing season.
Pest Control
Exposure to pesticides has been linked to a long list of
diseases and health problems. Pesticides contaminate the air,
water, soil, plants, and animals around us. Plants tend to thrive
in an organically-rich environment, which helps them fight off
pests on their own.
Learn which insects are beneficial in the garden. Some of these
garden-friendly bugs include praying mantis, lady bugs, damsel
flies and dragon flies. They all have voracious appetites and
consume large quantities of "bad" bugs such as aphids. Some insects
lay their eggs in the bodies of others. For example, the parasitic
wasp lays its eggs in the tomato horn worm. The wasp's larvae
eventually destroy the voracious horn worms.
Companion planting is based on the theory that certain plants
grown in close proximity to one another help each other thrive. For
example, tomatoes when planted near crops such as cabbage and
broccoli can repel the caterpillars of the diamondback moths. Other
plants attract insects that prey on pests that would otherwise
damage nearby plants. Beans, for example, attract insects that eat
leaf beetles, a pest of the corn plant.
Commercial Fertilizers
Organic fertilizers contain nutrients derived solely from the
remains or by-products of a once-living organism. In general,
organic fertilizers release nutrients over a longer period of time
than synthetics do. In addition to providing nutrients, organic
fertilizers increase the organic content of the soil, improve its
structure and increase bacterial and fungal activity which makes
nutrients more available to plants. In general, synthetic
fertilizers act more quickly than organic types. Be sure to read
the label carefully and follow the label instructions.
The amount of fertilizer needed depends on the natural fertility
of the soil, the amount of organic matter present, the type of
fertilizer being used, and the vegetables you are growing. The best
way to determine fertilizer needs is to have your soil tested. You
can buy soil test kits at garden centres and through online and
mail order catalogues.
Keep the Weeds Down
Weeds are a gardener's scourge and, admittedly, weeding is the
most disagreeable job in the garden. But, to get a good return on
your investment in time and money you have to eliminate the weeds.
By far the best defence against weeds is to spread mulch (such as
wood chips) between your plants. Eliminate weeds while they are
young by pulling them or scratching them out as soon as you see
them-and, don't let weeds go to seed!
The Vegetables
What you grow in your garden depends on what your family likes
to eat. Salad fixings like greens, tomatoes, cucumbers and peppers
are the most popular with home gardeners. Some vegetables such as
lettuce and cucumber can be planted directly into the garden from
seed after the danger of frost has passed. Others, like tomatoes or
peppers are better set out as young transplants because they
require a longer growing season to mature.
One of the best ways to decide what you want to grow is to check
out seed companies that sell organic seeds. For a list of organic
