Biodynamics
Pioneered by
Rudolf Steiner, a contemporary of Rachel Carson, this method of growing
calls for planting different varieties of plants so close together that
when they are reaching full-growth, the leaves touch. This is vastly
different than conventional growing which calls for row planting only
one variety with greater spacing.
The reason that biodynamics works is
that the plants create a mini-climate for each other, discouraging
weeds and pests, and conserving water and space. The intensively
planted varieties have complementary needs for space, sunlight, and
nutrients, completing one another’s space rather than competing for
space. This is an important place for utilizing companion planting
techniques.
