I water and
fertilize with regular tap water. The fertilizer
is a balanced 19-19-19 I have made with all the
trace elements. I use it 1/4 strength
absolutely all the time except when leaching the
plants.
Once a month
I leach the pots and wash the plants off with a
mix of magnesium sulfate (Epsom Salts).
This keeps the mineral buildup off the
leaves and out of the pots. I may do this
two or three times in a row before I go back to
the tap water and fertilizer.
The plant is
growing in a slotted clay pot I got from O.F.E.
years ago. The mix in the pot is medium fir
bark and #3 perlite, nothing more. The clay
pot idea was to keep the roots slightly cooler in
our hot climate.
