Dendrobium cuthbertsonii temp ranges

Not sure which Tom you were referring to but I have had mine for just over 1 year now. I have gotten mine to bloom and put out new growths so I would think it is safe to assume the temp ranges I am giving it are sufficient, but only time will tell I guess

It is funny as I moved to Daytona Beach right after I graduated high school and I missed the change of seasons and moved back to PA. I can honestly say though I can live without the change of seasons now and want to move to move south again but staying on the east coast

 

I was thinking about this today, and I will say that even though my growing area gets "too hot" in the summer, the mitigating factor is the cool down at night. So, IMHO you can grow plants above their "normal" range, IF you can cool them off, every night!

 

I think it is also very important to be sure to keep them cool at the roots as well during times of extreme heat.

 

If you can grow masdevallias and draculas, then Den. cuthbertsonii is a breeze. They enjoy cool conditions and are easy to grow and bloom. My primary problem was scale and trying to eradicate it without damaging the sensitive plant.

 

Yup, they are very sensitive to some chemicals. The oil based insecticide can do significant damage or kill the plants.

 

Mine never gets down any where near 50 in the summer time. As I mentioned above the average low is 64 over the summer but most hot summer days it is around 70 at night and can be that way through much of July and August

 

My intermediate/cool gowing area uses nothing more than the cheap t-12 shop lights with a mix of warm and cool tubes.

 

Don't move to Colorado. We don't need any more Texans.

 

It blooms here and lives quite well in San Diego (I don't have one), and our summer nights rarely have a low below 60. Most of our summer nights are in the high 60s (aka 67ish). Our days don't get much above 80 though.
