A short while ago, we came across a fantastic website www.ghorganics.com which is a Colorado based company promoting the organic cause. Here is an excerpt from the information on their site, plus a few additions from us.
Intercropping, companion planting or symbiotic planting are all techniques of growing different plants together or in succession, to deliver best results. Here is another good resource with loads of info: www.organicgardeninfo.com/intercropping.html.
Some common intercrops or companion plants are listed below and can help promote growth, fruit taste or quality and protect against diseases. (Does not eliminate need for pesticide or weeding though)
Holy Basil (Tulsi): Grow with Tomato’s, Capsicum, Oregano, Asparagus and Petunias. Basil is helpful in repelling thrips, flies and mosquitoes.
Bay leaf (Tamalpatra): With Beans. We Gujaratis have been putting tad patti or tamalpatra in each storage container of beans or grains to deter pests since kingdom come.
Beans: With Carrots, Corn, Brinjal, Cabbage, Cauliflower, Wheat and other grains. All beans enrich the soil with nitrogen fixed form the air, improving the conditions for whatever crop you plant after the beans are finished. Beans are great for heavy nitrogen users like corn and grain plants because the nitrogen used up by the corn and grains are replaced at the end of the season when the bean plants die back. Besides, remember the nursery rhyme we sang as kids?
Sorry, couldn’t resist. Hehe
Beetroot: With Lettuce, Onion, Cabbage, Good for fixing magnesium in soil, and that in turn helps plant take up nitrogen. Companions for beets are lettuce, onions and cabbage, cauliflower. Grow beets alongside garlic.
Chamomile, Mint, and Dill: plant with brassica like Cabbage and Cauliflower. Do not plant near tomato and chilly.
Broccoli: Mint, Garlic, Dill and Marigolds and Methi
Garlic: Roses, Cucumber, Pea, Tomato, Carrot …almost anything! It’s a great natural fungicide that is high in sulphur content.
