Years with no bloom

[K.C.]

Yes the north cost is under the clouds, most Vanda's need to be outside all summer if you won't to see them bloom.

warmth, humidity and bright light....I put mine outdoors in summer to direct sun....and in winter when everything is brightest (for there are no leaves on trees)...then you need to add supplement light to make it bloom.

Thank you Bud

I agree 100% - especially the latter. The bright green color "screams" excess nitrogen, which is well-known to quash blooming.

I used to think that excess nitrogen was a function of the formula used, and the 6-30-30 is a "low-N" formula, but now I realize that even a very low-N formula, if used too often and/or at to high a concentration, can give the same overdosing.

I am currently using a formula with a very high ratio (K-Lite @ 12-1-1), but use it at such a dilute application rate (35 ppm N), that I am avoiding all such issues.

That is one massive plant!! Good culture!! Well done!!

I had a Tolumnia that flowered once, then it died.

Hi, did it bloom since last year?

It as never bloomed

I still think it needs more light. My Tolumnia hybrids are a purplish green except for the newest young growths and they bloom fairly reliably. Mine get T5 light in winter and then bloom in spring. spring thru summer is natural light in a greenhouse. We get a lot of sun here, so you may need to leave it under lights, if you have a cloudy location.

I have put some of this outside all summer with out success but have never the given grow light treatment.

I think over winter at least it will need to be under several HO T5's or equivalent for 12 hrs/day.
