“Why would anyone spend the time on
trying to coax an orchid to grow?
Never mind getting it to bloom. They
are so fussy and difficult to grow.”
Those were my very thoughts after I
spent twenty five dollars on a tiny
orchid seedling only to see it
wither and die a few months later!
That was over ten years ago. Today I
have a greenhouse full of blooming
orchids and just love the challenge
of getting even the most stubborn
orchid to reveal its beauty with a
stunning display of inflorescence.
There has always been a certain
‘mystique’ attached to the orchid.
When orchids were first brought back
from the New World to European plant
collectors, it resulted in orchid
frenzy. Many orchid hunters and
collectors lost their lives looking
for new and unusual orchids to
satisfy the cravings of wealthy
European orchid hobbyists. Of course
there is the persistent story
concerning the infamous searches for
the elusive black orchid which
really doesn’t exist, in the wild
that is.
The mystique surrounding orchids
could discourage one from ever
trying to grow and flower this
beautiful plant. Fortunately this is
just a myth. Most orchids are not
that difficult to grow. If one can
grow African Violets, Boston Ferns,
or other care free houseplants, then
orchids should fit into the same
environment.
The best orchid for a novice grower
to try is the Phalaenopsis,
otherwise known as a Phal or Moth
Orchid. The flower colours vary from
pure white to almost black. There is
no other orchid flower in existence
that carries the variety of colours
and textures of the Phalaenopsis.
Several varieties have amazing
fragrances. An extra bonus is the
incredible longevity of the flowers.
The flower spike will often stay in
bloom for up to six months
Phalaenopsis hybrids have flowers
that range in size from ¾" to nearly
5" in diameter. The mystery and
beauty of a blooming orchid is very
intriguing. These attributes have
made Phalaenopsis orchids the second
most popular potted plant sold in
North America.
Phalaenopsis orchids enjoy a spot
near or in a bright window. An east
window is the best. A west facing
window is good, just watch for hot
direct sun which could scorch the
leaves. In the winter months or if
the window is shaded by a curtain or
by trees, a southern exposure is
okay. You can grow Phals under
fluorescent lights placed
approximately 1 foot above the
plant. Time your lights to simulate
normal day length. Limiting light
levels to 1,000 - 1,500 foot candles
will provide ideal light levels.
Phalaenopsis do well in temperatures
between 18° and 27° C. For optimum
growing try to maintain 18° at night
and between 22° and 27° during the
day. Temperatures in excess of 30°
can slow growth. Cool night time
temperatures in autumn encourage
flower spike initiation. Try adding
a pinch of Epsom salts to your
watering regimen at this time. This
often triggers flower spikes in
stubborn plants. Once the flower
spike is developed, avoid wide
swings in temperature as this can
cause unopened buds to drop off.
Phalaenopsis benefit from moderate
humidity levels. Ideal levels range
between 50 and 75% relative
humidity. In a heated home you will
want to set your plants on a
humidity tray, a shallow tray filled
with gravel and water. This should
help to keep the humidity near your
orchid at acceptable levels. Make
sure that the plants roots are NOT
sitting in water.
Proper watering of Phalaenopsis is
very important. Phals do not like to
be dry to the point of wilting.
Evenly moist is the ideal
environment for Phalaenopsis roots
to flourish. They should be watered
thoroughly and then not again until
the media is nearly, but not
completely, dry.
How often you water will depend on
the type of media used and its
growing environment. Begin by
watering your orchid approximately
once per week. The weight of the pot
can tell you if your plant needs to
be watered. Stick your finger into
the medium periodically and if it is
dry, make a mental note of the
weight. After a few weeks, you can
adjust the watering schedule by the
weight of the pot alone. Be careful
not to let water settle in the crown
of the plant where new leaves form
and avoid spraying or accumulating
water on the flowers as this will
damage them.
During the active growing period of
the orchid, use a fertilizer with
equal proportions of
N(Nitrogen)-P(Phosphorous)-K(Potash)
- for example 14-14-14. In
September, blossom booster
fertilizer such as 10-30-20 is
recommended. Apply fertilizers
with every second watering at 1/4
the recommended strength. This
dilute solution prevents burning of
roots and leaves.
Phalaenopsis need to be re-potted
about once a year. There are several
reasons for re-potting your orchid.
It may have outgrown its current
container, the media has decomposed
and is no longer aerated well enough
to maintain healthy roots, or the
roots may have rotted. Remove the
plant from its container and let the
old media fall away and carefully
trim away any rotting or dead roots.
Use a pot that just allows the root
ball to fit in. Position the plant
in the new container and pour in the
new potting media, letting it settle
around the roots. Orchid potting
media must provide air space at the
roots. Acceptable media includes a
fir bark mix containing sponge rock
and charcoal or other similar
materials. If you use bark, ensure
that you soak it at least overnight
and use only the floating bark in
your mix. New Zealand sphagnum moss
allows the development of healthy
and vigorous root systems and is the
media of choice for many growers.
After re-potting resume your normal
watering and fertilizing schedule.
Phalaenopsis Orchids should be
regularly monitored for aphids,
mealy bugs, mites, scale, and slugs.
Scale is one of the most common
pests of Phals and can be removed
with a soft cloth and soapy water or
a cotton swab soaked in isopropyl
alcohol. Cinnamon (a natural
fungicide), Safers Soap, and
Isopropyl alcohol are excellent
natural remedies to keep in your
orchid medicine chest. If you choose
to use a commercial pest control
product, be sure to carefully follow
all label instructions
If your Phalaenopsis orchids are
healthy, you can often urge a second
flowering from each spike with a
timely pruning. When the last flower
on the spike fades, examine the
spike for small fleshy bumps or
nodes. From the base of the spike,
count out 3 nodes and cut the spike
just above the third node. If your
plant is healthy and the season is
not too late, this process will wake
up one or two of the nodes and in a
few short weeks, it may produce a
few more fresh blooms. Keeps the
flower spike facing towards the
light source for more visual impact.
After the flower spike dries up, cut
it off about 1 inch from the base of
the plant.
When purchasing an orchid, look for
strong, healthy leaves, some
unopened flower buds, and be sure to
inspect it for insects or insect
damage. It is important to purchase
your orchid from a reputable orchid
grower. Purchasing a Phalaenopsis
from retail chains and hardware
stores often means the plant has
been subjected to a poor growing
environment which is not a healthy
start for your plant. An orchid
vendor will be able to help you with
your questions and be able to give
you advice.
These guidelines and suggestions
will make your Phalaenopsis
orchids bloom and grow for years
to come. Phalaenopsis orchids
blooming on your windowsill
during a cold February day is
truly one of life’s simple
pleasures.
