A handy guide to ‘Companion Planting’

Did you have resounding success in the past with certain crops without doing anything ‘special’? Did others fail, but you didn’t know why?

Companion planting could be the answer. Plants have always lived side by side; and sometimes they have benefited from this partnership. Sometimes it hasn’t worked out quite so well.
Companion planting involves growing a combination of plants that are of mutual benefit. Some have obvious benefits – growing carrots next to members of the allium family (onions, leeks, garlic etc) confuses and deters both the onion and the carrot root fly because the plants are so strongly scented. Herbs also have their uses – tarragon repels pests and is said to improve the flavour of most vegetables.

Here is a brief guide to companion planting – wherever possible, ‘bad matches’ should be planted as far away from each other as is feasible within your raised bed.
