I am a new member and would like to get help for my bulb sumatranum 'A-doritil'. I have had the plant for about a year ( I am in Miami), it does grow, has not bloomed and the tips of the leaves are turning brown. What am I doing wrong. The plant is in low light and I keep it moist like I was told when I bought it. I feed my orchids about every 10 days. Thanks for any help.
