media such as bark and moss compact and
deteriorate over time - especially in the heat of summer. Decaying
potting materials trap impurities
and restrict air flow at the roots. This
alters the chemistry and blocks many
nutrients from getting to the plant. Your plant is not only robbed from
getting what it needs - the unused nutrients turn to
salt and eventually become harmful to the roots.
If your planting
is old, your fertilizer could actually be harmng your plants! The only
solution is replacing the media.
system, LECA pebbles replace all other media. LECA pebbles are
a sterile ceramic that will never
compact or decompose, promoting an
even flow of air and
water over the roots. You'll never get
"exhausted media" with LECA, eliminating the "trapped nutrients
Removing impurities from the system
is also easy. Simply take your
plant to the sink every couple of
months (or use the garden hose if
outdoors) and leach the pebbles
thoroughly. The relatively smooth outer shell on the pebbles allows any
foreign matter to wash away. This is impossible with bark or moss.
