I have an extremely healthy orchid that I have had for many years. Recently for the first time a spike branch produced new flowers. The first bloom produced 10 large flowers. After cutting the spike below the last bloom, the branches have produced several smaller flowers. The plant has several air roots and is producing several new roots. Today I noticed that the older air roots are also sprouting new roots too?? Is this common? Why is the plant suddenly producing so many roots? What should I do?

It has likely been stuck in less than favorable conditions until recently. These will consistently produce new growth all year under the perfect conditions. This means that whatever has changed has been beneficial to the plant.
These orchids will flower once the daily light hours decrease below roughly 12 hours per day. Rather, they need at least 12 hours of pure darkness in order to initiate flowering. It would seem that they were able to reach this requirement.
