Many of these relationships are fairly general. The best results come from creating diversity by using a variety of herbs and ornamental plants alongside the edible crops planted in the garden.
Some Companion Plants are:
Basil helps repel flies and mosquitoes
Birch leaves encourage compost fermentation
Borage in the strawberry patch will increase the yield
Catnip repels fleas, ants and rodents
Caraway helps breakdown heavy soils
Chamomile deters flies and mosquitoes and gives strength to any plant growing nearby
Chives grown beneath apple trees will help to prevent apple scab; beneath roses will keep away aphids and blackspot.
Elderberry a general insecticide, the leaves encourage compost fermentation, the flowers and berries make good wine.
Fennel repel flies and ants
French Marigold root secretions kill nasty nematodes (not the beneficial ones) and will repel white fly amongst tomatoes.
Garlic helps keep aphids away from roses
Hyssop attracts cabbage white moth keeping brassicas free from infestation
Mint repels cabbage white moth. Dried and placed with clothes will repel clothes moth.
Nasturtium secrete a mustard oil, which many insects find attractive and will seek out, particularly the cabbage white moth. Alternatively, the flowers repel aphids and the cucumber beetle. The climbing variety grown up apple trees will repel codling moth.
Pyrethrum will repel bugs if grown around the vegetable garden
Rosemary repels carrot fly
Sage protects cabbages from cabbage white moth
Tansy (Tanacetum, not Senecio) repels moths, flies and ants. Plant beneath peach trees to repel harmful flying insects. Tansy leaves assist compost fermentation.
Wormwood (Artemesia, not Ambrosia) although it can inhibit the growth of plants near it, wormwood does repel moths and flies and keeps animals off the garden.
Sepp Holzer’s permaculture farm sits along steep mountainsides in Austria 1,500 meters above sea level. His farm is an intricate network of terraces, raised beds, ponds, waterways and tracks, well covered with productive fruit trees and other vegetation, with the farmhouse neatly nestling amongst them. This is in dramatic contrast to his neighbors’ spruce monoculture farms.
In his book, Sepp Holzer’s Permaculture: A Practical Guide to Small-Scale, Integrative Farming and Gardening, Holzer shares the skills and knowledge acquired over his lifetime. He covers every aspect of his farming methods, not just how to create a holistic system on the farm itself, but how to make a living from it. His farm now spans over 45 hectares of forest gardens, including 70 ponds, and is said to be the most consistent example of permaculture worldwide.
Chris Tidmarsh graduated from Hope College with a degree in chemistry and environmental studies. He got a job in environmental research but lost it shortly after and moved back home.
"Clearly, he needed a different path to apply his talents in the world of work," said his mother Jan Pilarski. Chris has autism.
"Nearly all of his peers with autism were chronically unemployed despite having post-secondary degrees," Pilarski wrote recently. “Our world seemed small and bleak. I didn’t have much hope to change the minds of potential employers to help Chris get a job. On the other hand, I saw an opportunity to be entrepreneurial about the staggering 90 percent unemployment rate confronting people with autism.”
