Companion Planting
August 19, 2005
A PRACTICE much loved by organic gardeners, the science behind companion planting, is only just beginning to be revealed.
The theory is that companion plants produce compounds that attract beneficial organisms or repel organisms that are pests or diseases.For example, nasturtiums produce a mustard oil that aphids dislike.Buckwheat produces nectar to feed parasitic wasps.
Although the wasps sound rather nasty, they are quite small and only attack insects such as leafroller caterpillars.
