Companion planting is so plants can help each other grow and survive
Gardening -
What is companion planting?
Companion planting is based on the idea that when planted in groupings, plants can
assist in the over- all well being of the garden.  For example; some plants add
nitrogen into the soil that is needed for the healthy growth of other plants.
Beneficial insets are attracted to certain types of plants, and some plants repel
insects.  Other plants can provide protection from the sun and wind for more
delicate plants.  Some weeds have a beneficial quality also.  The benefits of
companion planting include a natural method of pest control, a higher produce yield,
and a garden that is visually more appealing.

With the exception of fennel, most herbs planted in or near vegetable beds will
have a beneficial effect. Try planting herbs at the corners of beds to ward off
flies and various insects and to attract bees.

planting:
