Singing The Alocasia Blues
January 10, 2008
After years of growing a variety of plants, I’ve formed specific relationships with
different types. I have had – and continue to have - a great relationship with
my Aglaonemas and Dracaenas. We get along remarkably well, and everyone is
happy. Right before the holidays, I added some Philodendrons to my collection,
plants that fall all over themselves to please you. I never realized how
terrific they are. What took me so long to bring some home?
My Dieffenbachias and I have an amicable relationship ever since we came to an
understanding. I understand their needs and apply them accordingly. They
understand that if they don't perform well after I've met those needs, they'll
end up at the curb. So far, so good.
My Ponytail Palm, Sago Palm and Desert Rose – plants I was hesitant about when we
first met - seem to appreciate me and my efforts. All three are doing
wonderfully, and I’m flattered by their approval. The Spider plants never make
any demands, the Snake plants win awards regularly for ‘best performance’ and
the Pothos grows like a weed. My Hoya, which I’m still not convinced is not
artificial, is thriving, and my Bromeliads hold a special place in my heart –
never whining, always thriving.
After many moons, and several discarded specimens, the Crotons are finally stable,
particularly now that I’m being (grudgingly) more responsible and finally
providing the ample light and sufficient humidity that they demand. In lieu of
that, I’ve been daring and reckless in the past twelve months – more than any
other period of my plant growing years - and actually added more than one of
these plants to my collection. Ooooh...it’s fun living dangerously...
Peace Lilies and I have a rocky but recurring relationship. I love these plants and
can’t seem to live without them for too long. Whenever one fails, I get another
one. The latest one has been around for quite some time. Maybe there’s hope
yet.
The (plant) love of my life is my Euphorbia Milii; it’s always happy and always full of
blooms - all year round. The Goldfish Plant (Nematanthus Gregarius) is not far behind with its undemanding
nature and its eagerness to produce those charming, bright orange flowers. And
the few Orchids that I own are growing happily in their hydroculture setups.
These are just a few of the satisfied customers in my green world. All in all, I can
honestly say that almost every plant under my care is showing signs of
contentment and appreciation, which builds my confidence (and strokes my ego).
Except for the evil Alocasia Amazonica. (Take a deep breath...hold it...exhale...) Now
here’s a plant that has been testing my patience since the moment I brought it
home. I pamper it to death and provide a stable environment. Instead of showing
some gratitude, it plays head games. One month it’s shooting out a few new
leaves and the next month it’s dropping them. No matter how much I try (plead),
eventually it turns on me, getting down to one leaf that slowly, dramatically,
withers and dies. Then when I’m finally ready to toss it (secretly happy to
unburden myself from it), I notice the slightest hint of a new leaf emerging
and I’m compelled to start the abusive cycle all over again. Okay, I could stop
the mistreatment if I really wanted to, but I’m convinced (this is called foolish
pride) that I can conquer this plant.
By the way, I’m on my third. The first one was devoured by spider mites, which, by the way,
an Alocasia is highly-susceptible to. I neglected to check the plant for a long
time and the mites literally took over, wrapping entire leaves in webs. I tried
treating it but by then the plant was so weak that it started dropping its foliage.
In addition, other insects had jumped on the bandwagon. It was a horror film in
the making and I was happy to be rid of it.
My second Alocasia was doing wonderfully for a long time, growing one new leaf after
another. I was afraid to touch it in fear that I’d curse or upset it, but it
continued to grow happily no matter what. For awhile. Then one summer day, I
noticed a leaf changing colours. The next day it began to wilt. By the end of
the week it had died and the rest of the leaves had begun to check out as well.
It was all downhill after that. Out of frustration, I tossed out that Alocasia,
refusing to go through the cruel cycle again. Alright, I’ll admit I just wanted
to free up the space for another plant.
The third one, the one I have banished to my teenage daughter’s room, is down to one
leaf. I’m willing to give this plant the benefit of the doubt that it has gone somewhat
dormant for the winter - or for whatever reason an Alocasia feels compelled to
go dormant at any given time. When spring comes, if there are no signs of new
growth, out it goes. And if that happens, I swear this will be my last attempt
at growing this plant. No, I mean it this time. Really. Is that laughing I
hear?
Alright, now that you’ve had your fun, here is some care information about this
striking, albeit temperamental, beauty.
Temperamental But Beautiful
Despite my bellyaching, the Alocasia Amazonica is not the most difficult plant to grow.
It’s not the easiest, and I certainly would never recommend it to a beginner,
but it’s not impossible to grow inside an average home - at least not if you
are fairly knowledgeable about houseplants. And even though it may be a tad
high-strung and slightly demanding about its needs, it’s such an astonishingly
beautiful plant that you can’t help but forgive it its shortcomings. Not forever, mind
you; every one has their breaking point. Just ask the Gardenias
if they’re welcome here anymore.
There are about 70 species of Alocasia, but the Amazonica - commonly
referred to as African Mask or Shield Plant - is the one you will find
frequently available at local stores. If you are planning on purchasing one of
these ornamental plants, my advice to you is to pick one up as soon as a
shipment of them has arrived. Alocasias deteriorate rapidly if their needs are
not fulfilled properly (and promptly), and they end up looking terrible. They
seem to forget (or they just don’t care) that there are oodles of other plants
in the greenhouse that need attention, and that the staff is doing the best
they can. So pick one up while it’s still fresh.
It is possible that your newly-purchased Alocasia may throw a small tantrum the first
couple of weeks inside your house. It may drop a leaf or two to protest the unpleasant
change from humid greenhouse to dry home. Don’t fret; it will adjust
(reluctantly at first) as long as you provide the care it needs.
High levels of humidity are one of the most important factors in keeping this plant in
good shape. Aside from brown leaf tips and the loss of leaves, spider mite
infestations will become a huge problem if this plant is grown in hot, dry air.
Add a humidifier nearby, place the plant on a pebble tray, surround the pot
with damp peat or simply place it in a room where humidity is naturally higher,
like a bathroom. For more information: Improving Humidity
If you peek through a few houseplant books, or do a search on the internet, you will
find a diversity of opinions on how much light this plant really needs.
Suggestions include: full shade, partial shade, bright light, bright but
indirect light, morning sun, late afternoon sun, no sun (ever) and medium light.
By the time you’re done researching about this plant, your head will be spinning.
Since light varies from home to home, and is affected by so many other factors or
obstacles (curtains, trees, buildings, weather, season, screens), my advice to
you is this: place your Alocasia near a bright window, out of the direct path
of sun, and watch for signs of approval or disapproval. If your plant is
leaning towards the light, something an Alocasia will do readily if the spot
you’ve placed it in is too dim, move it closer to the window. Although I would
never recommend placing this gorgeous plant in a low light area, I would also
never recommend placing it in the path of hot, midday sun. A bright spot with indirect
sun is typically ideal.
Use a porous, fast-draining medium and keep it evenly moist during the growing season.
Allow it to dry somewhat in the winter, but never completely. Protect from cold
drafts and keep your Alocasia in warm temperatures. If this plant dries out
completely, or gets chilled, it will drop its leaves and go dormant.
Fortunately, it grows new leaves promptly when you’ve remedied the situation
(and learned your lesson).
Alocasias are prone to spider mite attacks but there is no reason on earth for the bugs
to take over. Infestations will never get out of hand if you practice
preventive measures to keep them at bay. Open windows regularly, and run floor
or ceiling fans to circulate the air. Clean the leaves of your plant every
month. Take the plant to your kitchen or bathroom sink and rinse the leaves
under running water. You can also wipe the leaves with a damp sponge or give the
plant a shower in the bathtub. If you’re treating an infested plant, keep
humidity high (Alocasia will thank you!) to discourage pests from multiplying
faster than you can get rid of them. More importantly, keep your plant in
tiptop shape by watering properly and providing adequate light and humidity
levels. A healthy plant utilizes its own resources to defend itself against
infestations while a plant under stress is much more vulnerable to them.
This is a prime candidate for the hydroculture system. Conversion is fairly rapid with
little or no signs of stress. Alocasia is also part of a select group of plants
that suspend new growth during the transplanting process rather than discarding
it. After water roots develop, the plant resumes growth of the new, unfurled
foliage.
Alocasias are sensitive and their needs must be met accordingly to keep them happy. If you’re
not willing to make that extra effort, don’t take one of these lovely plants
home, it’ll disappoint you. And you’ll end up singing the Alocasia blues.
(Incidentally, I was inspired to write about my Alocasia after reading the
article Criminal

Strangest People
