I have several Amaryllis bulbs starting to bloom. Will removing the pistil extend the life of the bloom?
I can't see any reason why it would with an amaryllis or any other flower. Lilies, though, will last slightly longer if the pollen is carefully removed because the pollen falls easily and can cause damage to the flower and therefore shorten the bloom's life, but it's not necessary to remove the stamens or pistil. Lilies and Amaryllis do not belong to the same Families of plants; Amaryllis do not seem to have the same problem with pollen.
The first one had 4 flowers open within a day, I cut pistils from two as a test ( what could go wrong ?). Nov 30, 2019 at 3:22
