Hi,
I'm new to the forum and to Vanda orchids and I need some help! I purchased my first Vanda (Ascocenda) about a year ago (in bloom) and have been working to get it to rebloom since. It is in a pot coarse bark and it seems to be healthy as I have had about 8" of new (big) root growth and about 8 new leaves. Unfortunately, no new flower spike.

I live in southern Wisconsin and give the orchid as much light as I can (even added a grow light for 3 extra hours per day in late winter which has helped lighten the green of the leaves). It's in a window with southern exposure. I mist daily and fertilize with 19-31-17 orchid fertilizer. I water twice a week (one soaking, lighter watering midweek). All my Paph's rebloom and are healthy. Indoor temps are between 55-70 year round, however humidity is low. I am running a humidifier have the Vanda over a water tray and manage to hold the humidity to about 40-50%.

I have noticed that the Vanda's older flower spikes emerged about every other or every third leaf. I have had about 12 new leafs since last spike. Does this mean that something is not triggering flower spikes and all the energy is going to the leaves?

Perhaps I am just being impatient, but any advice would be appreciated.

Cheers, Bob
