It depends.....
Where is 10b in the USA?
What sort of "Vanda" is it?
Do you have a plant name tag?
I've flowered some "vandas", had nil success with others which either grow or decline and have nil flowers.
Some with Vanda coerulea influence are a little bit more cold tolerant, so are those with with Neofinetia influence.

Two hours a day of sun is not enough. You should be thinking of at least six and probably eight. Nothing to do with fertilizer. Good luck. -Ian.

I agree with ifraser25. Just remember to only give it a little more sun with each step. I would go so far as to say, that it needs alot more sun. Also I would say you need to water that vanda at least every single day. I grow in New York in a greenhouse and water mine every day and the summer many times twice a day. Water and Sun is the answer. I maybe have 50 of them growing and something is always in spike, bud or flower. My best vanda of all is Vanda Pats Delight (not Roberts Delilght). That puppy is always in bloom or spike. In the summer it even has two spikes in flower every once in a while.

Are you getting it really watered when you water it? If you can soak it in a container for awhile to get those roots really wet it could help too. I also agree that it needs more sun (done gradually).

hi
would assume it's a "strap" leaf as opposed to a 'terete " The latter having round pencil like leaves ??
Another is Mokara an intergeneric hybrid but all are cultured the same Would agree with the others as to the method particularly in florida I grow mine in a shadehouse as well as in a bed between two palms .to allow the roots to run wild lol. Only on my third year with the experiment getting rampant growth but only two have flowered but both were very high quality so am very optomistic One strap was removed from the group and returned to the shadehouse were in had the most spectacularlar flowering in years . Go figure ?? lol
Good luck gary

I'm a newbie and live in West Broward. My Vandas are hanging in my oak trees. I try to fert every 2 weeks and water 3x a week if it hasn't rained. I have 3 in bloom now and 3 more in spike. I vote for more sun and fertilizer.
Google or find on facebook MOTES ORCHIDS. He does a monthly check list for S. Florida orchids.

I have moved my vanda in a more brighter place where it receives sunlight in the morning and late afternoon, it got me an spike after 2 weeks in winter though i bought it in bloom in hot summer . I water twice daily feeds it twice a week they are happy so i am happy. 😁

Updating on my vanda post from 7 yrs ago..lol...it finally spiked. I attached the pic of the flower although not a very good picture. The flower was actually much more of a pink. I stuck it in a tree and forgot about it. It has 2 new plants coming and is very healthy. It tried to set 3 more spikes but they seemed to dry up although it gets enough water. I also have had another vanda for many yrs that has never spiked but finally it has but not flowered yet. These plants are tall. Not sure what variety. Wow...it's the year of the vanda for me.

WOW, you waited 12 years for it to bloom! Congratulations!

12 years and you are in Florida?? I feel bad for those of us northerners that rely on in home conditions..Congrats

I don't think I'd wait 12 yrs for anything! I tried to grow a Vanda in NY and gave up after 3 yrs. Gave it away.

In Florida, they hang in the trees, southern exposure, rarely fertilized (I can't remember the last time), water once in a while, but they always bloom their heads off.

Vandas need sun more than anything else. Water is great, but I find sun is the main need.

Oops, I just bought mid sized seedlings of a Vanda and a mokara. I guess I will never see them bloom.....

Thanks for all your comments...it took 12 years, yes but I didn't actually wait (well sort of...lol). I did give up on it and stuck it in a tree and let it do what ever it was going to do. Living in Florida, I do have the luxury and advantage of the weather.
