i have 3 12" clay pots filled with h. papillio that don't bloom. i have them outdoors in the bay area spring to fall, and two are in an unheated greenhouse with little water in the winter and one pot is in a heated greehouse and gets watered. all 3 just limp along. they were blooming when i bought them 10 years ago and seem to have made offsets, but no bloom. i fertilize them with the rest of my mix of orchids, bromeliads, gingers, ferns, etc, with various soluble fertilizers, alternated, at half-strength. do i divide them, fertilize more, different kind of rest, something else? i would search the archives, but i don't see a search function best, john menlo park, ca
