Dtps. Tzu Chiang Orange Safe to Cut Spike???

[Cattleya17]

Hello im sure you guys get asked this alot. i was wondering if you can do this with all phals? i know that the more exotic types such as bellina tend to bloom from the same spikes for years!!! but i Have a Dtps. Tzu Chiang Orange that finished blooming about a month mybe 2 month ago. already made a new leaf which has fully expanded and is now growing roots!!! so i wanna know if its safe to cut this spike. Im hoping that cutting it will help to initiate some more blooms especially since the days are shortening and it gett ing cooler at night, which i know initiates spiking in some. the spike is still green. does this make a difference???? Please, Despite the frequency in sure you get asked this can You Please Help me!!!!!!!! I just dont wanna mess anything up
