I have a lady slipper orchid that is in bloom. Should I fertilize it while it is blooming? Thanks for an answer. Dee

Lady Slipper Orchids are one of my favorite flowers!
In general, Paphiopedilum thrive on less fertilizer than that required by the other genera. If plant is in bark, use high-nitrogen (30-10-10) during growing season. Otherwise use a balanced fertilizer (25-25-25). That said, rather than fertilizing weekly as you would with Phalaenopsis, fertilize every other week in half-strength and make sure to flush the fertilizer with clear water once a month. Paphs can be fertilized once a month in winter.
