Vanda has turned yellow in the middle with leaves falling off... Help!
I recently received a Vanda orchid for Christmas that was in bloom. Since then, the stem has turned black, and the middle of the plant has turned yellow with many leaves coming off. It is currently in a glass vase with wine corks at the bottom. I let the roots soak for 15 mins everyday in water, and use fertilizer about once a week. Please help! I'm new with orchids and don't know what to do!
