I'm the same. Mine went out in high light as early in the year as I thought the temps would be alright and it started spiking off an old cane no long afterwards. It has had so much light it's got a red tint... but seems really happy.

This gives me hope! I have 2 NOID phal type dendrobiums (both pretty large in size) that were given to me as gifts that have not rebloomed in 18 months.:bua: I had them inside last summer, but this April I put them outside - one in full morning sun and one in full late afternoon (after 3pm) sun. Both are putting out new canes, but still no spikes. If increased light intensity is driving all of your blooms, then hopefully it'll work this year for me!:pray: If not, then it's full sun for most of the day and they'll either bloom or fry!

The mature canes with leaves from last season will probably be the first to bloom. Keep checking at the tips and a few nodes back. The new growths will have to mature before blooming. You might not see any action out of the new growths till next spring.

To prevent sunburn...Check your leaves frequently while they're transitioning to higher light. Too much sun will rapidly result in areas of color fade and leaves that feel hot to the touch. These symptoms indicate the need for a little more shade. Good luck! :)

o have one that is blooming from previously bloomed canes. one cane has two spikes!

:cheer::cheer::cheer:

that sounds like what mine get

Mine get a red tint when in hight light which indicates it's very high but not yet burning them. Not all of them may get this though (probably genetic) one of mine burns before it turns red and also burns in the same light that the others seem to like.

I summer Dendrobium bigibbum var compactum outdoors where it gets direct sunlight from sunrise to noon, and then indirect sunlight for the rest of the day. It often and easily spikes from previously bloomed pseudobulbs. I have noticed that older leafless pseudobulbs tend to produce keikis, profusely. It winters indoors under CFL lights and does not produce as many new flower spikes as during summer outdoors. The Bakers' culture sheets say that bigibbum seldom grow into large clumps and old pseudobulbs prone to die back - this is true in my experience.

Junebug, may i know the id of the white + purple dendro in your previous post? I have something similar.

Wish I could help, but all of my phal type dendrobiums are noids. Without a name tag it's anyone's guess...but only a guess.;)
