Very nice Pheli, I have one but it isn't going to blossom for me. I'm not doing something I should be.
Was so hoping I would get a whif this year......
Al, B. nodosa usually blooms from early autumn till late winter. If your plant has some new growths that are growing actively, they may come to bloom while the pseudobulbs get matured.
Moderate dryness and enough sunlight will be helpful for them to flower.
Mine finally bloomed this summer after doing nothing for about a year. It bloomed one flower which scented up my entire patio every evening for about 5 weeks! It smelled like honeysuckle.
