Vanda Losing Leaves-Pictures
 

So i bought this Vanda from a very respectable grower and i have had it about a week. it sits under a palm tree outside all day hanging. gets partial shade all day and gets watered every other day. The lower leaves have started to turn a different color and are limp/starting to peel off. Now if you can tell, new roots are growing rapidly all inbetween these leaves and many of them are splitting the leaves that are falling off. Also our neighbors sprinklers go off everyday and it could be getting the plant wet with sprinkler water. What are your thoughts on why it is doing this?

It should be fine they like water as they have no bulbs for storage . They will do that.
I think as long as you are getting new roots where the leaves are falling should be fine mine do the same .. Nice spike :)

nice big roots...the leaves are experiencing cold water and the inner part of the leaf must dry before wetting it again...it is best to just wet the roots than the leaves except once a week when fertilizing(back of leaves have to be wet with fertilizer to nurture the plant effectively
I make it a point to water vandas in room temp or tepid water from the sink
the hose outdoors must run to air temp before it touches the roots or else cold water doesnt make happy vandas

Just sounds like its shedding it's old leaves as it grows new roots and prepares for more, newer leaves. That would be my guess.

There is no cold water from my watering i mist the roots only every other day till they are dripping and come back 10 min later and repeat. leaves never really get wet and the water in the mister is at least 75. its 85-90 outside in the day and 75 at night

I turn the hose on mine when they are outside lolol

The extra water shouldn't be a problem, since Vandas grown bare-root in baskets like that need to be watered daily. As for the leaves, I agree with what's already been said - the plant is perfectly healthy, and the leaves are merely being pushed off by the new roots. It's no biggie, really. If you take good care of your plant, it should replace the lost leaves rather quickly.

If you put the vanda in a new spot it may be getting more light than it was getting before. That's probably a good thing. It may be growing new roots because it needs plenty of moisture in a brighter location. Roots growing through leaves is normal and loosing a few leaves when you put the orchid in a new location is also normal. I just had a flower spike grow through a leaf on one of my vandas. The extra water from the sprinklers won't hurt unless it's in the evening. Vandas should be watered early in the day like most orchids.

I keep my Vanda hanging under a palm tree outside it gets partial shade all day, I mist roots, wait 10 min mist again in the morning and repeat around 4 when i get home from school. living in south Florida i will be able to keep outside year round. I will keep it in this spot until it blooms then i will bring it in the screen enclosure, then back outside after bloom cycle has finished. Im excited to see the flowers will post pics!

Thanks for all the help. To me it seems logical that it is cause by the roots because there are no problems with the leaves above where the roots are.

I experience something similar, though less severe, every time I move or obtain a new vanda. My take on it is it is adjusting to more light and less water - that is why it is throwing out those big thick roots.
If you water more, you may not lose as many leaves during the transition.

Leaf drop could also be the result of nutrient deficiencies. You may want to consider that as a possibility as well in the future.

Although in this particular case, I think it's from old leaves like the others have said.

what kind of water schedule do you recommend? its about 85 in the day with 85% humidity

Could just be adjusting to it new home...give it time. If it continues to do this after it has acclimated, then you can worry- but not now. Give it a good 3-5 weeks to adjust...

every day until it adjusts
