As Companion Plants

Practiced
by organic gardeners for years, companion planting has become very
popular with gardeners. The concept is to plant together species
which will benefit each other, and help prevent disease and insect
infestation without the use of chemicals. In general, herbs and
other aromatic plants like tomatoes, marigolds and onions are helpful
in warding off insects. Certain colors, like the orange of nasturtium
flowers, are thought to repel flying insects. While these practices
have not been scientifically proven, many gardeners have been using
them for years. Try it - and see if it works for you!
