Thanks for answering my question about blogging. I think that it's awesome that you are "singing to your hearts content". To answer your question, I've seen orchid flowers last 6 weeks sometimes. That is a long time for flowers! Most orchids say to water them once a week. Mine get a little bit of direct sunlight in the morning and lots of bright light for at least 6 hours. I do feed them liquid plant food when I see the plants putting on new buds and continue feeding them while they have flowers. This white orchid is a new one I just bought with the flowers in bloom.
