Companion
Planting
By Abigal Gordon
Carrots Love Tomatoes: Secrets of Companion Planting for Successful Gardening
|
Companion planting is the
placement of various crops in close physical proximity to on another
so as to symbiotically compliment the progress of each other.
One traditional practice was planting of corn and pole beans
together. The cornstalk would serve as a trellis for the beans to
climb. The inclusion of squash with these two plants completes the
Three Sisters technique, pioneered by Native American peoples.
Companion planting was widely touted in the 1970s as part of the
organic gardening movement. It was encouraged not for pragmatic
reasons like trellising, but rather with the idea that different
species of plant may thrive more when close together. It is also a
technique frequently used in permaculture, together with mulching,
polyculture, and crop rotation.
The combinations of plants also make for a more varied, attractive
vegetable garden. Many of the modern principles of companion
planting were present many centuries ago in the cottage garden.
|
Companion plants can benefit each other in a number of
different ways, including:
- Flavor enhancement — some plants,
especially herbs, seem to subtly change the flavor
of other plants around them. Such as Basil is known
to enhance the flavor of tomatoes.
- Hedged investment — multiple plants in
the same space increase the odds of some yield being
given, even if one category encounters catastrophic
issues
- Level interaction — plants which grow on
different levels in the same space, perhaps
providing ground cover or working as a trellis for
another plant
- Nitrogen fixation — plants which fix
nitrogen in the ground, making it available to other
plants
- Pest suppression — plants which repel
insects, plants, or other pests like nematodes or
fungi, through chemical means
- Positive hosting — attracts or is
inhabited by insects or other organisms which
benefit plants, as with ladybugs or some "good
nematodes"
- Protective shelter — one plant type of
plant may serve as a wind break, or shade from
noonday sun, for another
- Trap Cropping — plants which attract
pests away from others

Sweet corn in a heavy

nutrients from the soil. Plant some
climbing beans at the base of each corn
stalk. The stalk will support the beans,
while the climbing beans' roots will fix
nitrogen from the air into the soil
where its needed most. |
