Why won't my orchid bloom, and why are the leaves turning yellow? Plant has not bloomed for about 1 year. Lots of roots growing on outside. No new leaves in the last 6 to 8 months. Water weekly. Since May have fed twice a month with orchid food following directions on bottle for dilution. Keep plant is window that gets afternoon sun.
This looks like a Phalaenopsis orchid. A reason for poor bloom includes low light levels. See our website for more information and care http://extension.umd.edu/hgic/care-phalaenopsis-orchids-moth-orchid
