The Q&A Archives: Getting Crocosmias to Bloom

Question: I live in zone 5 - have a beautiful growth of crocosmia 'Lucifer', but have never had any blooms on them. They get probably 8 hours of sun. Perhaps it is planting depth? Do you have any ideas?

Answer: Crocosmias do best in full sun, a little afternoon shade in hot inland areas. They like their soil a little on the lean side, not too rich with organic matter, not too well fertilized (0-5-5 or similar proportions is good), and not too wet. Planting depth is approximately 4 times the height of the bulb (maybe half that in heavy soils). Plant bulbs close. Toward the end of the season, cut off supplemental watering all together to allow the bulbs to ripen before digging. In your area, bulbs should be dug each fall and treated as you would gladiolus: stored dry and warm (not hot). Good luck.
