Companion planting in gardening and agriculture is planting of different crops in close physical proximity. It is a form of polyculture. Polyculture is agriculture using multiple crops in the same space, in imitation of the diversity of natural ecosystems, and avoiding large stands of single crops, or monoculture. ...


One traditional practice was planting of corn (maize) 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. A trellis is a frame-like structure on which vined plants can grow. ... The Three Sisters are the three main agricultural crops of Native Americans in North America: squash, maize (or corn), and climbing beans. ... A Hupa man, 1923 The term indigenous peoples of the Americas encompasses the inhabitants of the Americas before the arrival of the European explorers in the 15th century, as well as many present-day ethnic groups who identify themselves with those historical 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, changing of crops, ... It has been suggested that this article or section be merged with Organic horticulture. ...


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. Cottage gardens are attributed to English origin and are typically random and carefree in form. ...


For example:


Nasturtium are well-known to attract caterpillars, so planting them alongside or around vegetables such as lettuce or cabbage will protect them, as the egg-laying insects will tend to prefer the nasturtium. Species About 80 species, including: Full List of Tropaeolum species * In older traditional systems placed in the Geraniales Nasturtium (literally nose-twister), as a common name, is a genus of roughly 80 species of annual and perennial herbaceous flowering plants Tropaeolum, one of three genera in the family Tropaeolaceae. ... The striking caterpillar of the Emperor Gum Moth This article is about insect larva. ...


Crops which suffer from greenfly and other aphids may benefit from the proximity of marigolds: these attract hoverflies, a predator of aphids, and are also said to deter other pests. Families There are 10 families: Adelgidae - adelgids, conifer aphids Anoeciidae Aphididae Drepanosiphidae Homomasagymibutae Greenideidae Hormaphididae Lachnidae Mindaridae Pemphigidae Phloeomyzidae Phylloxeridae Thelaxidae Aphids, also known as greenfly/blackfly or plantlice, are minute plant-feeding insects in the superfamily Aphidoidea in the homopterous division of the order Hemiptera. ... Families Adelgidae Aphididae Pemphigidae Phylloxeridae and several more Aphids (superfamily Aphidoidea) are small plant-sucking insects. ... Species About 20, see text : also numerous garden hybrids and cultivars The marigolds, genus Calendula L., are a genus of about 20 species of annual or perennial herbaceous plants in the daisy family Asteraceae, native to the Mediterranean region and Macaronesia. ... Genera many genera about 5,000 species The flower flies or hoverflies are a family of flies (Diptera), scientifically termed Syrphidae. ...


The use of plants that produce copious nectar and protein-rich pollen in a vegetable garden is a good way to enhance the population of beneficial insects that control pests. Some insects in the adult form are nectar or pollen feeders, while in the larval form they are voracious predators of pest insects. SEM image of pollen grains from a variety of common plants: sunflower (Helianthus annuus), morning glory (Ipomoea purpurea), hollyhock (Sildalcea malviflora), lily (Lilium auratum), primrose (Oenothera fruticosa), and castor bean (Ricinus communis). ... This snapping turtle is trying to make a meal of a Canada goose, but the goose is too wary. ...


Another movement utilizing companion planting is that of the forest garden, where companion plants are intermingled to create an actual ecosystem, emulating the interaction of up to seven levels of plants in a forest or woodland. Forest gardening (also known as 3-Dimensional Gardening) is a food production and land management system based on replicating woodland edge ecosystems, substituting trees (such as fruit or nut trees), bushes, shrubs, herbs and vegetables which have yields directly useful to humankind. ...

Companion Plant Categories

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.
  • 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, or other pests like nematoes 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
  • Root Substance ---some plants give off susbtances that kill or repell other plants and insects
