David’s Monthly Orchid Tip April 2010
David Off is a 3rd generation
member of the highly respected
WALDOR ORCHIDS family.
First decide whether you simply want to shift
your plant or divide it into several pieces. To shift
your orchid, remove the plant from the pot and
clean the old mix off the roots. Then choose the
proper pot size allowing room for two years of
When dividing cattleyas and other orchids with
similar growing habits, we recommend leaving 3-5
bulbs per division. Decide what size cutting you
want to make. Then use a sterile knife to cut down
through the rhizome and the roots staying as close
as possible to the older growth.
Next consider what type of container will suit
your orchid and watering schedule. Most orchids
grow well in plastic pots. However, if you have a
tendency to over-water, clay pots may work better
for you since they are porous and will dry out
faster. Clay pots, because of their extra weight,
will also help top-heavy plants to remain upright.
We recommend potting in a fir bark mix.
Orchids like good drainage, so we suggest using
large bark or sytrofoam peanuts in the bottom of
the pot. Place the plant with the newest growth
farthest from the edge of the pot and fill in with
mix. Make sure to get the right level for the
potting medium. Be careful not to bury the eyes at
the bottom of the bulbs and leave some room for
water in the top of the pot.
If you are potting in sphagnum moss, just
remove the old medium and choose the proper pot
size depending on the amount of roots. Spread the
roots over a cone of moss, then wrap some more
moss around the root ball and place it into the new
pot. Phalaenopsis should be centered in the pot,
while orchids that grow like a cattleya need to be
placed with the new growth farthest from the edge
of the container. Be sure to cover all the roots.
Moss should be spongy and should not be packed
