You can leave the spike on or - cut it off. Some believe that cutting a spike helps Phal to focus on growing roots. Others say that the spike will dry naturally when it has to.
I always cut mine off. It doesn't hurt the plant but rather signals that it times to recharge the batteries.
From what I can see they are fine. Nice plump and green. But I haven't repotted yet cause it was still flowering. . . Thats why I was asking cause I want it to concentrate on root development. It already grew another leaf not to long ago
I always cut my spikes just above the third notch, and the plant, if it is healthy, will usually put out a couple of side shoots with more flowers. This is especially true when you buy a sale orchid at Lowe's and don't know what the flowers will look like.
