BigBill said:It will flower again from the inflorescence, just with fewer flowers then the first time.
It does take some time, maybe 2-3 weeks for it to swell and start to grow, maybe another 4-6 weeks to get it long enough to produce buds and for them to open.
I would have cut it back to a node below the branched spike.
BigBill said:On the main inflorescence, below the branch, I would cut it an inch above one of the nodes. There should be at least two below, maybe a third.
BigBill said:Orchids are not heavy feeders in general. Too much fertilizer can actually keep some orchids from blooming properly. If you have to use it, use it spareingly, maybe three times a year. Weakly as well.
If it was my Phalaenopsis, I would have it bloom just a second time only. Then I would cut the spike all the way back.
You can bloom it to death in that all its energy goes into producing more and more flowers to make you happy. It really could use the chance to stop blooming and make more roots and leaves so that it gets healthier and happier moving forward!
