I bought a new Vanda a week and a half ago, and i got it a bit cheaper becourse its condition. It was a bit dehydratet, with shriveled roots and leafs.
It had a lot of roots, but some of those where very dryed out, almost like strngs, not plump as they should be. And some seemed good, plump but white unless just after watering when they turned green. There where some new roots-growth at the tip of the shriveled roots, that got green when watering.
Now the roots seems to got worse... Its lost some of the shriveled under watering, and the tips turns yellow after watering instead of green. Those who where green from the beginning, and plump, still looks good, but theres not as many of those that i would preffere... Its growing a new leaf as well, but its still between the top leafs. This was present when i bougth it.
In the day, when its warm and sunny it is outside, but now comes the autum here, and theres less of those sunny days. If it is raining, or is colder, its hanging in a south window during the day, and abowe an open terrarium (to encrease humidity) during the night. It gets a little exstra light in the evening, when i move it abowe the terrarium so it will get about 10 hours with light. I also have a fan thats running some hours every day. It getting water/misted every day when it warm and sunny, and about every third day when its cloudy, and its getting the extra light.
Now to the worry... When i water, some of the roots does not turn green, but yellow. Mostly its the tips of the shriveled ones. And the leafs are still shriveled.
Some pics will show what i mean...
The first is before watering, the second is of the leafs. The last two is after watering, and shows the colors, green and yellow...
What am i doing wrong!?!
