Watering Vanda

[bdelfiero]

This morning, I've noticed that some of my Vanda roots are turning brown and dying and I'm worried because there are no new roots forming to replace the dying roots. I am confused because some websites on the internet suggests to water them at least twice a day during warm season. ( We have a year round warm temperature) My Vandas are all outside with very bright filtered sun and the temperature is around 30Cto 32C, and the Humidity is around 50 to 60%.

Could this be over watering? or I should water them once a day? Should I use something to grow more roots?

Thank you.

Vanda roots like a lot of air circulation. Do you grow your plants potted or with roots exposed?

Hi Jun, I forgot to mention that the roots are very much expose and hanging. Though some roots turns green every time I water but there are roots that are dying.

I don't know if this additional information will work. They finished their blooms 3 weeks ago. Though, I don't see dormancy in any of them because I see some new leaf growth but no root growth and I'm a little bit worried because they say healthy Vanda produces some healthy roots. Is it normal for Vandas after the blooms?
