I've grown cyms in less ideal conditions than those I see here and they still bloom. Try a couple in there and see how they do. But put them in the sunniest part of the room. Let us know how they do.

Obviously, the lack of cool temps is not your problem here. Lack of enough light may be and I agree with the "trial and error" suggestion made by James. However, I would add to that to concentrate on the smaller sized Cymbidiums, referred to as "Miniature" or "Novelty". These tend to be more tolerant of conditions like yours, take up less space and definitely will give you more blooms for the size of the plant.

Pendent or cascading Cyms are very popular. Their care is the same. Hang them and enjoy the blooms on spikes that arch and fall over the edge of the pot. Many of the hybrids also tend to be VERY floriferous. For references, visit the Santa Barbara Orchid Estate website to see some of these. I am sure they are also available in your area with a little searching of orchid nurseries.

Good Luck,

Your winter temp is similar to Southern California. Most Cymbidiums grow like weed in this climate. I would keep them outdoor with 50% shade. Bring them indoor only when they are in-bloom to enjoy.

Gaz,

One point you did not address was how hot does this area get during your summer? The only reason I suggested the Miniature or Novelty type Cyms. was as a "space saver" or with the assumption the room may stay warmer than the standards prefer, although most Cym. hybrids will all survive nicely in temps that swing from near freezing to the occasional 100F. The keys here would be adequate humidity and good air circulation.

The bottom line is that Cyms. really want to be outdoors with good air circulation, 50% shade and humidity, and temperature ideally between 45F and 90F with the occasional 5F-10F variable at each end tolerable for a very short period. The closer you can get to these conditions, the better luck you will have in growing and blooming them well.

Thanks CL,
Our summers can get hot that's for sure... especially when there's a westerly breeze. Where I live in Sydney, we usually get a pleasant coastal breeze. It goes without saying that I've had quite a bit of damage to my garden outside from the westerly, from time to time.

Humidity is between 50% - 70% all year round... so that's kind of ideal for orchids I guess.

The average temperature in Summer is 25C degrees (77 for you)... but can get up around 40 (103) for four or five days of the year... my plants are probably far better off inside on those days, and when the westerly blowing.


I think I can manage pretty good air circulation as we enjoy that right through the house now, I open a bank of glass louvres are one end of the house and open the roof at the other. I put the space with operable louvres there for that purpose originally.. so I have ventilation covered.... and humidity provided naturally.... the questionable component seems to be light.... and of course water management.

Gaz,

Orchid growing for all of us is a trial and error procedure. We learn as much as we can to give each genera what it wants within our own personal limitations of our environment. Many times we try to fit a "square peg into a round hole" and find it simply does not work that way with orchids. :rofl:

In the end, we wind up with what we like and do the best we can to benefit our plants. Always keep your mind open to change and improvement, no matter what. We, as growers, have to learn to adapt too. :twocents:

I think you will do just fine with your Cymbidiums if you keep in mind what they want and the problems you know you have to watch for. Good luck.
