Well after 6 years, I finally have some blooms! There were 2 large root systems for years. I finally removed one this spring and within 3 weeks had 2 spikes. Do you think the removed 4 foot root system was using up all the energy?

Great Sheryl!
I’m sure the roots didn’t use up the energy. But cutting one “root system” may have triggered the blooming. I have to think about this further

Maybe doing that damage triggered a survival response.
I’m wondering if a dry spell normally triggers V denisoniana to bloom. If so, maybe cutting the roots had the same impact as a dry spell.
Regardless, I will give my denisoniana a dry spell right now.

Not sure. But it's had the same conditions all these years. Good theory! Thanks Arne!

Wouldn't a survival response have created more roots?

Thank you Bruce!
By survival response I think Ray means the plant's attempt to produce a progeny before it goes further downhill.
So I talked to a real Vanda specialist about what makes V denisoniana bloom. He mentioned two things, strong light (preferably from all sides) and, very wide temperature difference between day and night.
According to Charles and Margaret Baker the diurnal temperature range for V denisoniana is actually about 25 - 30 degrees F from January to March when it flowers in its natural habitat in Thailand.
