Resistance To Cordylines Is Futile
June 17, 2008
We just recently got through the first full-blown heat wave of the year, followed by a
mini-sized one and I can’t stress enough how glad I am that they’re both over –
at least for now. While I’m dreading this summer, which is predicted to be a
hot and humid one, and I really, really, really can’t stand very hot days, I’ll
take that over the long, cold, snowy winters, which I’ve complained about in many previous
Hydro Logs. I really, really don’t like winter with its
drawn-out periods of bitter weather and gloomy days. I mean really.
But for now the winter is gone and the weather is not bad and I’m feeling pretty darn
good because of it. No cold, no heat, just a perfect period where some days
offer a refreshing breeze. It’s the time of year that makes you want to walk
for miles, which I have been doing fairly regularly most evenings with my dear
hubby. But usually not on Wednesday nights.
On those nights, we go out for a quick supper with the family and then head off to do some
shopping. We’ve chosen midweek as our paper-goods-and-other-household-items
shopping spree because it’s fairly quiet at the stores at that time as opposed
to Thursday or Friday evenings or Saturday and Sunday afternoons. The shopping
itself is just a chore but after I’ve ticked off the items on my list and placed
them in the shopping cart, I claim (demand) a little time to myself and take a stroll
through the section of the store that offers a small, but sometimes impressive,
selection of houseplants. Generally, there are two stores that are involved in
our weekly shopping outings, both of which offer a houseplant section,
sometimes good, sometimes bad:
1) Home Depot. There is one store near my house that is completely unpredictable in its
selection of plants from one visit to another. One week you’ll walk in and find
oodles of newly-arrived, healthy and captivating plants. Two weeks later, many
of those plants will still be there, with no new arrivals in sight, and
everything that has yet to be sold will look like it’s been run over by a truck
- twice. If nothing else, the random visits to Home Depot can be kind of fun,
especially when you go there with someone else who can lead you to the
greenhouse while you keep your eyes closed. Once you get there, they can yell
SURPRISE, you open your eyes and - voila! – you’ll either find a heavenly
assortment of plants - or death and destruction, botanical style.
2) Wal-Mart. I’m at one of these stores just about every week. Yes I know many of you don’t
like this place, but I do, and I certainly don’t apologize for feeling this way.
And although they don’t have the greatest selection of houseplants on a regular
basis, once in awhile you hit the jackpot. For example, I have landed some
great choices throughout the years such as my Adenium Obesum, most of my
bromeliads and a variety of other interesting plants. Usually they offer the
common, available-everywhere-all-year-round types, but now and then they bring
in some original choices that aren’t very accessible, and others that -
although not the most exotic - are nicer than the average
available-everywhere-all-year-round types. So you can get lucky.
Anyhow, the whole point of this is that big box stores can – and do – offer some really
great deals for indoor plants every so often and I personally think these places
are worth a visit. Granted, the plants are not the best cared for (because the
employees looking after them are not very experienced in that area) but if you
know when these stores bring in new shipments – and you show up on those days –
you can head home with some healthy, beautiful (and occasionally rare)
specimens at amazing prices.
That’s how I brought home some lovely Cordylines, which are some of my favourite
indoor plants. And I’ll admit that they’re not the most exotic or all that
difficult to find, but they’re not always available and they are lovely enough
to get excited about when you run across them. So I’m going to write a little
about them because they’re certainly worth mentioning. And well, here goes...
Taking Care Of Cordylines
Inexperienced (and even experienced) growers often mistake Cordylines for Dracaenas, which they’re
not, although the care for both is very similar. Native to Southeast Asia, Northeastern
Australia, Papua New Guinea, Melanesia and parts of Polynesia, these attractive plants are also
known by the common names of Ti Plant and Hawaiian Good Luck Plant. And although they’re
not native to Hawaii and New Zealand, Cordylines are growing as feral weeds in those areas,
having been introduced by Polynesian settlers. Or so I’ve discovered from researching. Anyhow.
The leaves of Cordylines are what give these plants their charm but in order for them to
retain their vibrant shades, high light that is direct or indirect must be
provided for a few hours a day. In the winter time, let your plants enjoy some
direct early morning eastern or late afternoon western sun. You can even try a
couple of hours of southern sun during the colder months; if your plants are happy
there, great, if not, move them to another location or filter the light. During
the summer season, especially on those really hot days, curtain-filtered
sunlight should be fine, although you might want to move your plants a little
further back from a southern window to protect against the heat and to avoid
possible sunburns. In any case, these are the type of plants that will help you
determine how much light to offer. If the light is too low, the colours on the
leaves will not be very prominent and the plants will lose their appeal; if the
light is too high, the colours will fade and the foliage will look bleached.
Cordylines are similar to quite a few Dracaenas with their watering needs: they belong to
the water-juggling association that is obviously meant to drive houseplant
growers mad, especially beginners. They do not like to dry out completely but
they will rot easily if over-watered. Their leaves will turn brown when
under-watered and sickly yellow when over-watered. The best advice I can offer,
which is repetitive, is to use a fast-draining, porous soil that does not
compact; this will help prevent rot, which will occur easily in a constantly
waterlogged potting mix. Keep the soil evenly moist but not soggy; reduce
watering in the winter but don’t let the plants dry out completely. Although it
seems somewhat intimidating when it comes to watering Cordylines, if you use an
airy medium, you won’t need to worry.
To put an end to water woes, convert your Cordylines to hydroculture. Conversion is fairly
quick and the plants do not complain very much during the transition. Wash the
roots carefully to remove all traces of soil and pot the plants in clay
pellets. Water roots should appear within 1 – 2 months, sometimes as early as 2
weeks, depending on the plants and time of year. Keep the humidity levels high
during this period to reduce stress – for your plant, not you!
If you want something to worry about with these plants, worry about humidity. Although
Cordylines can manage fairly well with average moisture levels, they prefer a
high level of ambient humidity. If the air is too dry, you can be guaranteed of
two things: ugly brown tips and margins on the leaves, and spider mites. The
leaves will dry to a crisp if the air is too dry and the plant will look awful.
And although Cordylines are generally pest-free, the evil mites will not
hesitate to move in if humidity levels plummet. So keep moisture levels
reasonably high. Place your plants on a humidity tray, grow them in a room that
offers higher levels of moisture naturally (like a bathroom) or add a
humidifier nearby. Don’t compromise this is you can help it; your plants will
be much healthier and happier if you meet this requirement. The spider mites
will be less happy but we don’t care about their feelings, do we?
Do not fertilize heavily or too often. The leaves of Cordylines burn and turn crispy
if overfed, or they become a sickly yellow/orange shade. Opinions differ
considerably from book to book and grower to grower, but in my opinion, less is
always best. Just like with Spathiphyllums,
once a month – or every six weeks – from April to September with a mild
fertilizer at ½ recommended strength seems to do the trick. If your plants are
showing signs of being overfed, reduce fertilizer to ¼ recommended strength or
feed only 3 times during the active growing season. Average household
temperatures that keep you comfortable will keep your Cordylines comfortable.
There is sensitivity to cold; protect plants from cold drafts and do not expose
to temperatures below 13°C (55°F).
All in all, Cordylines make wonderful houseplants, although they can be a little
tricky with their need for high humidity. But if you can satisfy that
requirement to a reasonable level, you should have no problem at all with them.
If you happen to run across a few of these lovely plants, which there aren’t
that many of on the market, consider trying them out. They’re really worth an
effort. And most times, they’re available in small sizes with affordable price
tags attached to their pots.
From what I’ve been able to gather, there are only about 15 – 20 species of Cordylines,
although I’ve only encountered 2 or 3 different types at the local greenhouses.
So there aren’t that many available for indoor growing, which may be a very
good thing – at least for people like me. These plants are so attractive, it
would be impossible to resist bringing home one of each if I had the chance.
And with limited space always being a factor, I don’t need more plants to add
to my already large group, more plants to cater to. And if you love houseplants
as much as I do, you know exactly what I’m talking about – resistance to beautiful
plants (like the ones in the Cordyline clan) is futile. Oh yeah.
