I have had this Vanda crownfox "sunshine" asconcentrum for 3 years. It was purchased from one of my favorite nurseries, R.F. Orchids. Every year it blooms prolifically.
Since I live in North Carolina, it is grown indoors in the winter under 4 T5 bulbs for 12 hrs/day. The humidity is between 35 - 45% in the winter with help of a humidifier.
I watered with rain water about every 4 days in the winter. It spends the summer outdoors where it receives morning sun.
About 3 months ago the roots stopped growing. Please take a look at the photos and let me known what you think, any input is appreciated. There is no longer any new growth of leaves.
I fertilize with MSU, once a week in the winter with 1/4 strength. Summertime I normally increase the frequency where every 5th watering is plain water.
I can't see anything with a 20X Bausch and Lomb loupe.
This is absolutely one of my favorites, gorgeous huge yellow long lasting flowers. Please help me save her. Thank you.
