Orchids - getting them to flower again
I have 3 orchids which flowered 18 months to 2 years ago. They've produced new leaves and roots, but as yet no new flower stems. I know I cut the stems on the first plant I bought back too far, which may have caused a problem with this one. I water the orchids every 10 days or so with rain water and a pinch of orchid food.
What do I need to do to get them to flower again?!
