Mtssa x Milt blooming question
I have a large Mtssa Aztec vs Milt regnelli cross that was in bloom when I got it 2 years ago. However, it hasnt bloomed since. It is in a bright east-facing window in Washington DC. Other orchids in the same area that have bloomed reliably for me include Hawkinsara (Koolau Sunset), Burrageara Nelly Iser and Brassidium Wild Warrior Chieftain. So I am guessing that light levels are not the problem. The plant is growing vigorously in Leca and I fertilize with Dyna-Grow using the manufacturers recommended dilutions as for the my other orchids. Room temperature is ~68-72ÃÂC although the temperature on the window sill reaches 85ÃÂC during the day in summer. Could it be that the winter night time temperatures are not low enough?
