Thoughts on cutting a Phalaenopsis spike
Given a healthy Phalaenopsis hybrid, grown under natural light, that has finished blooming, one has 3 options regarding the flowerless spike:
1. Let it be. The plant will decide what's best for it. (After all, in nature nobody cuts any spike.) If the spike goes completely dry, one can cut it at the base, for aesthetic reasons.
2. Cut the spike above the highest green node, to give the plant the chance to rebloom from a side spike. The plant will decide if it will take this opportunity or not.
3. Cut the spike at the base, to "force" the plant to grow a new spike. (Again: this is about a healthy plant, with plenty of roots and leaves, grown under natural light.)
Option 2 can lead to sequential blooming on the old spike, increasing the average blooming time, but the flowers are likely to be fewer and smaller. Option 3 can lead to more and larger flowers, but after a longer time, because it takes longer for new spike to grow and bloom. Sometimes it can be difficult to choose.
Now, I have noticed that a new spike initiated in fall and blooming somewhere in winter will be shorter and will bear fewer/smaller flowers anyway (as opposed to a summer spike). Therefore, I would go for option 2 if the plant finishes blooming in summer/fall, in order to "postpone" any new spike for a brighter season.
On the other hand, if the orchid finishes blooming in winter/spring, I would go for option 3 in order to increase the chances of having a new spike growing in the best light.
Does this make sense to you?
