Dendrobiums blooming, spiking, and growing

[NYCorchidman]

All of my dendrobiums are responding well to high light window setup by sending up new shoot, some are sending up spikes, some are still in bloom.

It is fun to see how some hybrids start out very small, then boom! while others start out thick and fat, and keep on getting tall and thick. Very interesting plants.

Some of my dens got slightly burned, either small black spots or overall purplish cast on leaves and canes, so I moved thosed away. Some of them seem to be perfectly fine under high light.
Two of my white dens are showing white/yellow streaks on new growths. hmmm....wouldn't be too sad to them go if it is virus as whites are easy to find. I'm just going to let it grow and see how it will progress.

Wow - fabulous!

Those are beautiful...just curious, what is that white netting in front of the plants and where can I buy some? I need something to diffuse the bright light in a south window to keep some of my orchids from burning...

Thanks,
Eddie

Thank you, everyone! I love them!
Eddie- Believe it or not, the white netting is my sheer curtain. The regular sheer curtain you see at most curtain shops tend to block way too much light for my dendrobiums, so these are perfect for me.

I bought these at IKEA. You could check their website. It was like $10 and I only used half package. great stuff!!!

The purple striping is not a virus on the cane. It just means that one of the parents back there had purple striping canes.

Check out Den puchellum canes. They have lots of purple striping. I have one and lots of stripes. Looks very healthy.

I mentioned white/yellow streaks on leaves as a potential sign of virus, not purple stripes.
Purple stripes are natural for some hybrids, especially when exposed to high light, it becomes more intense.

Sorry about that. Was reading too fast. Lots of dendroiums can have variegation when exposed to high light. If you see white then drying then tan, it is likely too much sun. Happens to me a lot down here in the intense summers. As long as you don't see a crippled/virused bloom you are probably okay.

Of course the nobile hybrids lose their leaves so the yellow striping is normal in the fall. Some will lose their leaves late if there is a cold snap and then will bloom again. That happened to me last year. Got two bloom cycles.

The spatulata/phalaenopsis types will stripe in very high light and eventually it damages the leaf so extra shade cloth would be needed.

I didn't see anything on yours that would alarm me but I couldn't see the leaf up close.

The blooms are great.

Yeah, I need a better picture. The yellow/light green streaks are pretty bad and I'm thinking of tossing it. They are definitely not sunburn. I burned a few leaves
I have two white "hard cane" that are showing these streaks and these white ones are the most common here, so I'm going to be ok without them. I am thinking of buying just colored ones as I have been now and if I miss white dendrobiums, then I'll just go to a store and buy a bunch of cutflowers, which usually last me two months in the vase anyways with much higher flower counts.
With all the baby dendrobiums I am propagating, I need more space anyways.

By the way, my nobiles never get streaks in the fall. They just turn plain bright yellow before falling off.
I found Fancy Angel Lycee very sensitive to temerature drop and bloom any time of the year, which is crazy in a nice way.

gotta love dendrobiums!

Wow, there's so much color at your place! Dens obviously do very well for you. The fourth one (peach-orange) looks so much like Catt blooms!

Aren't Dendrobiums fun?! Yours are marvelous! Do you put them outside for the summer, or is that their permanent home???
