I had a vanda given too me about 3 years ago. It is very tall with lots roots but does not seem to bloom. I do fertlize it, just won't bloom.
Here is a link to refresh you on the growing requirements.
Pay attentions to light, temperature and humidity.
Do not over fertilize, this will inhibit flowering.

How to propagate Vanda Orchids.
Vanda Orchids grow from a single stem.
Propagation will require cutting the tip of the plant that has aerial roots.
You should be able to see the aerial root emerging from the branch, generally between sets of leaves.
With a sharp and clean knife cut the tip of the plant just below where the roots emerge.
This is a transplant ready cutting.
Put this cutting in a new pot with orchid substrate.
Water the cutting and make sure the water drains away.
Over watering and the cutting will die.
After planting you can use a 20-20-20 orchid fertilizer on the cutting.

I have a vanda orchid in a small wooden type tiny in size with only base in box with roots coming open slots sides. It hangs from a black metal stand in my Florida room. It looks great and I have had it since February of this year. I grow many different kinds of orchids but never this type. All of my other orchids always say to trim dead or dried up roots off. I haven't done it to the vanda but did so today. I should of checked this first, so I sure hope I made the right decision. I have always had luck in growing orchids so I guess that's why I trusted myself first. Please tell me if this was the correct decision to of made. Thanks. Mellanie Crooker
Vanda roots that turn brown or mushy have died or are aging.
It is fine to trim away these roots. Leave only the healthy green or white roots.
This may also be the time to repot your Orchid and give it a larger basket to grow in.
Dividing in late spring or early summer is recommended.
Here are some links with more information.

After the blooms die and fall off, do I cut the plant back?
You can dead head the spent flower stem.

My Vanda is in the greenhouse along with tomatoes, peppers, etc. I usually submerge the root daily with a weak feed. It has vigorous root growth and first signs of a flower bud. I am going away for 10 days and wondering if I leave a container of water close to the orchid, will it get enough moisture from the air? Or would it be better to get someone to water it? Regards malcolm
I would recommend having someone water your Vanda. Most orchids would survive just fine without being watered for 10 days, but Vanda orchids are much more sensitive to water stress than most others. It sounds like your orchid is grown with its roots in the air and not in a pot, which will make it more sensitive to water stress as well.
My vanda orchid flowered 3 times without problem, then for the last 2 times, the flower dried before opening and I have not moved the plant. It is attached to a palm tree. What do you suggest?
The flower issue is likely environmental issue. To hot, lack of humidity or even to wet of conditions may certainly be the problem.
Inspect the plant and roots to rule out disease. You can treat any issues if found, with Neem Oil.
This works and both an insecticide and fungicide.

The leaves on my vanda are turning brown. It is in a box with roots exposed and orchid food in netting around the base of the plant. Is it being over fertilized? Carol
Browning leaves can be due to disease, bacterial and fungal, root rot, over fertilizing, poor lighting and lack of humidity.
