Phalaenopsis wont spike!

[pikuangel]

About 4-5 years ago, I bought my first phal. Before I knew much about them, I cut the spike completely off because I thought that's what you were supposed to do. Now, many years later, it still hasn't produced a new spike. The leaves are green and it continues to grow additional leaves and roots. How do I get it to bloom again?? I don't even remember what color it is because it has been ages since I've seen it bloom. Is there anything I can do??!
