After visiting Al's greenhouse I followed his style of not cutting the old
spike on the Phal gigantea in hopes it would rebloom during the next bloom
period. After checking back with him it appears that the old spike grew a
bit during the last cycle but did not produce more flowers.

Does anyone know what happens to the old flower spike on Phal gigantea? It
appears to be green and healthy but can I expect another flush of flowers?

Good growing,
Gene
