vanda tesselata dropping leaves

[King_of_orchid_growing:)]

Might be too wet.

Remove moss. Use large grade bark. Cut back on water. Let the roots breathe. If the roots are shriveling and dying, then increase water. If not, then there's no need to keep watering the orchid.

The root tips on your plant is suggesting the start of some root damage, probably from getting them too wet.

If the air's stale, get it moving.

Temperature that you have in your growing area should not be an issue with Vanda tessellata. They grow well in intermediate temperatures.

I agree. I once had a vandaceous orchid that lost it's leaves the same way. When I figured out that I was over watering, it was too late and I lost it.

In my limited Vanda experience.....
Growing under, metal halide in my case.
No media in the plastic baskets
Misted daily
Humidity in plant room 40% up to 60%

I agree that the moss should come out of the basket and switch to something much more breathable. Larger bark, LECA, chunks of cork even!

What are the roots looking like?

Yes Vanda's do like loads of air around the roots, but I do have a Vandopsis lissochiloides which is also experiencing leaf drop and I have read that it grows more in a terrestrial habit, with it's roots in rocky cracks and whatever organic matter collects.

Are your other successful Vanda's species or hybrids which are growing under the T5 lights? Hybrids can be more adaptable to our growing conditions.

I took out the moss in the pot today and the roots underneath the moss were dead. When i did put the moss, it was airy but with the watering and misting, the moss was pushed down eventually and got concentrated at the bottom. So the bottom roots died and i guess that was the culprit. No moss now and i had cut off the dead roots and will mist it daily or 3x a week since the humidity around it is high. I have hybrids and species both such as pachara delights which i just posted in the vanda section a month ago. Sanderiana, coerulea, renanthera, and several more hybrids.

Perhaps a wooden basket would be a consideration.

I have been feeding kelpmax since spring of this year and gave me great results! I took out all the moss too and found that the roots had died underneath of it. So now im just waiting if it improves.

	Mistking Looking for a misting system? Look no further. Automated misting systems from MistKing are used by multitude of plant enthusiasts and are perfect for Orchids. Systems feature run dry pumps, ZipDrip valve, adjustable black nozzles, per second control! Automatically mist one growing shelf or a greenhouse full of Orchids. See MistKing testimonials

I use orchidata bark or lava rock (the red landscaping kind from Lowes) for my vandas with a spanish moss covering. Your tessellata likes it warm and humid. Dropping of leaves indicate root loss or too dry of the conditions. So I would just recommend you to take all of the moss and replace it with lava rock or orchidata bark.
