Ananas Comosus – The Pineapple
October 15, 2009
The geese are heading south, the leaves of the trees are starting to change colours, the days are getting shorter, the squirrels are fighting with the birds over what little food is available and it’s getting cold enough at night to require heating. This is when I start getting houseplant fever.
What is houseplant fever, water roots lady?
Well, dear readers, every year around this time, as the botanical life starts to die around me outside and the
inevitable arrival of winter is on the horizon, I begin feeling the need to visit greenhouses where I can
stroll through all the beautiful houseplants that are alive and well and looking for good homes. And while I
don’t always end up taking something home, I have been known to cave in occasionally, mostly when a) I spot
something that I’ve been trying to find for a long time or b) I see something that I’ve never grown before and
would like to give it a try or c) the price is right. Okay, option c is not entirely true. Even if the price is
right, if I don’t like the plant, it doesn’t matter. So, it should read instead: the price is right for a
plant that I like. There.
Anyway.
So, yeah, houseplant fever is kicking in just about now and I find myself dropping in at places that sell
houseplants to see if there’s anything interesting. I’ve been hoping real hard that I’ll run across some
bromeliads that I’ve never grown before. But only slightly. Because I know I won’t be able to resist if
I do find something different and it will upset me because bromeliads are - more often than not –
ridiculously priced and I really don’t like paying too much for a plant. Yes, I know this problem can be
solved by my staying away from greenhouses and all the temptations that go with it, but that’s just not an
option. Sorry.
In addition to bromeliads, I have somewhat of a weakness for Dieffenbachias, Aglaonemas and Dracaenas. Cost is
not a problem since most of these plants are reasonably priced, but selection is; I always see the same
choices available, all of which I’m presently growing or have grown at some point. Marantas induce
hyperventilation, especially the Calatheas, but I force myself to look away. These plants look beautiful at
the greenhouse and horrible within a few short weeks at home, if you can’t give them what they need. And
since I’m not always in the mood for all the added effort, unless the plant is unbelievably stunning, I walk
away. I can be strong, you know.
Moving on to the point of this article.
(Hey, is that a collective sigh of relief that I hear?)
The other day, I happened upon an Ananas comosus (which I already have, so there was no dilemma about
whether I should buy it or not) and thought to myself “I don’t think I’ve written anything yet about this
plant. Maybe I should” And self said “Sounds good to me”
So here I am with some care info about this lovely bromeliad that I hope will be helpful to some of you
How To Care For An Ananas Comosus
The first thing I’m going to tell you is that Ananas comosus is not an epiphyte like
Aechmea fasciata or Vriesea splendens
or the cute little Tillandsia plants, all of which
are bromeliad cousins. What this means is that if you expose the roots of this lovely plant to the air by
removing them from the soil (or whatever other growing medium you’re using, like clay pellets) to attach
them to driftwood or a seashell or some type of magnet, you will kill this plant. This is a terrestrial
bromeliad and it needs to be grown in a pot with an appropriate medium. So, don’t go pulling any epiphytic
moves with this bromeliad. Big no-no. Capiche?
Okay.
Now that we’ve got that out of the way, I’m going to tell you another thing: this plant is very easy to
grow indoors provided you aren’t growing one for the fruit; the chances of your Ananas comosus
producing a pineapple – no matter how perfect the growing conditions - are very slim. Very. Grow it for its
interesting foliage and its ease of cultivation, not its fruit. If you want pineapple, visit your local
grocery store.
So.
Alright, now let’s talk about care, starting with light, which Ananas comosus needs lots of.
Especially sun. Provide this bromeliads with plenty of bright light, preferably a few hours of sunshine a day.
Without adequate light, it will stop growing (or grow very slowly) and the leaves with be smaller, thinner.
This terrestrial must receive adequate amounts of light; if you can’t provide that, don’t grow it.
Choose an airy, fast-growing medium and water thoroughly when the plant is thirsty; do not water again until
the plant dries somewhat. Ananas comosus is a prime candidate for rot from over-watering, so it’s wise
to be careful with the watering can. Reduce watering significantly during the winter when the plant is resting.
This is a great candidate for hydroculture. Simply remove the plant from the pot, wash the roots free of soil
and place in a container with clay pebbles. Water roots should form within 4 to 6 weeks.
Like all bromeliads, above average humidity levels between 40 to 60 percent are greatly appreciated but often
difficult to maintain in the average home, especially during the colder months of the year when heating systems
cause humidity levels to plummet. Increase humidity if possible, but don’t fret; Ananas comosus tolerates
dry air better than most indoor plants.
Average room temperatures are fine but if you’re determined to try and make your Ananas comosus bear
fruit, temperatures of 24°C (75°F) and above may be required. When the plant is a few years old, it may produce
a sturdy stem bearing small flowers that are surrounded by pretty, colourful bracts. Soon after, a small fruit
will appear. Even though this whole process is not easily achieved when this plant is cultivated indoors, it’s
certainly worth a try; you really have nothing to lose.
During the active growing season, if your plant is growing in ideal conditions, feed it every two weeks or
once a month with a general liquid fertilizer that is diluted to half strength or less. Do not feed during
the winter months or if your plant is growing in poor lighting.
That’s all there is to it folks; it doesn’t get any easier than this. This plant is definitely worth trying
indoors, as long as you have a sunny spot for it.
