I recently bought a milt. (spectabilis 'Royalea' AM/AOS x Seminole Sand 'Angel' that was in bloom. I was wondering if anyone could tell me how long it should stay in bloom and what I should do with the spikes once the blooms fade? It has 5 spikes in bloom and 2 yet to bloom. It seems like some of the flowers are starting to fade and I have had it for a week or so. It is in need of a repot after this blooming.
