For over 4,000 years Plant Container Technology has not changed!
THE BIGGEST PROBLEM with the typical plant container is oxygenation. The
basic idea of the container is to hold soil and water…unfortunately that same design
keeps oxygen out. In the field of horticulture, it is well known that roots of all plant
species need oxygen for growth, health, and good production. In nature, the essential
supply of oxygen comes mainly and freely from soil air. However, in the case of
container plants, conditions for
oxygenation of root systems
are less than ideal.
Plant containers,
predominantly of the same
functional and simple “crock”
design (quadric cylinder), have
been used for plant cultivation
for over 4,000 years. Because
the “crock” design is easy to
fabricate, this straightforward
model has gone unchanged for
centuries. Unfortunately, the
idea of confining a static
volume of soil sets up a poor
condition for aeration,
especially in the interior core
of the container. Amongst
other vessel limitations,
aeration is reduced as a direct
effect of soil depth predicting
that conditions decline as the
container size is increased.
Additionally, the cultivated
mineral soils used for planting
soon become compacted
creating large mechanical
impedance and poor aeration
that inhibit the vitality of roots leading to impaired growth, reduced plant health, and
in the case of food producing species, reduced yields.
