Gantessa Stone's Container
Gardening With Pumice
Billions of plants are produced and
grown in shallow-drained container
soils, including containers, the
shallowness induces capillary
retention of too much water which
displaces soil air and causes poor soil
aeration.
The subsequent reduced oxygen
supply to the roots often reduces
root growth and function to the
extent they are unable to absorb
even the inadequate resident
water supply.
Natural soils are therefore
generally unsuitable for
direct use in shallow
containers.
The obvious practical
compensation for insufficient
water content is increased
irrigation frequency.
Although the potentially
available water supply is
enhanced, inadequate
aeration is only worse.
The correction of poor drainage usually
involves a soil physical amendment to
increase the proportion of large pores
and ensure adequate drainage and
aeration A variety of materials are used
for soil amendment, Pumice being one
of them.
The moisture characteristic of pumice
is probably the single best assessment
of a soil's physical suitability because it
elucidates the nature of its porosity,
thereby increasing water retention and
aeration following irrigation and
drainage.
Pumice is a mineral
composed of aluminum
silicate plus potassium and
sodium oxides.
Use pumice as a
topdressing to assimilate
water that puddles around
plants.
For succulents jeopardized by
delicate, wet soil, utilize a
metal bar or sweeper handle to
circle the plant with vertical
passages a few feet down.
