Where do I cut my Phalaenopsis after it blooms?


Where do I cut my Phalaenopsis spike? is on the short list of frequently asked questions at the Fuqua Orchid Center.

Yes, it's sad to say goodbye to your Moth Orchid spike. A year is a long time to wait for more flowers. But you don't have to wait an entire year. If you remove the spike in the right location you can produce a second flush of flowers from the same spike in a few months. It's easy!

1. Choose a clean sharp cutting tool. See my earlier post on cutting tools for orchids if you're wondering what tool to use.

2. Take a close look at your Phal spike. You will see a series of beige bands (called bracts) that encircle the spike at approximately 5" intervals. In the photo below one bract is visible just above the green twist tie. See where the beige bract widens and becomes shield-shaped? Beneath that protective bract is an inactive bud. 

By cutting the spike just above that bud you remove the inhibitory hormones that are holding the bud's growth in check. The cells inside the bud then differentiate into a flower spike. In a few weeks you will see the new spike begin to elongate.

3. Make the cut. Holding the spike securely with one hand, make your cut about one quarter inch above the beige bract.

4. What  now? Hang onto your bamboo stake as you will need it to stake the elongating spike once it is about eight inches tall.

Sometimes the bud produces a small plantlet, or keiki, rather than a new flower spike. After the young plantlet has produced a couple of roots about three inches in length before you can remove it from the old spike and pot it up.

Two additional things to think about:
  • If your plant is weak or in need of repotting, it's best to repot and allow your plant to rest and recuperate this summer without the additional strain of producing a second spike. 
  • Don't get too excited thinking that all of your orchids will produce a second flush of flowers in this way. Not true! Only a few--some Epidendrums and Oncidiums--do this.

  1. Great Blog! I am new to Orchids and just made my first purchase today. I got four Phalaenopsis Orchids. They are in bloom now and seem pretty healthy. I look forward to future blogs. Thanks:)

  2. Recently, my wife bought some succulent house plants as part of our home decor. I really love how she manage to arranged and compliment the plants with the way our house looks like. Now, what I am suggesting to her is for us to buy some orchids that we can put on our garden.

  3. What if I cut the bloom spike clear to the base of the plant, Will it ever bloom again?

  4. thank you for the great post! I have yet to have a bloom come from a cane cut slightly above the beige shield. But maybe that was because I used scissors, rather than a sharp blade? Today I surgically removed an extensive spike (with multiple off shoots), using a razor blade. I am anxious to see if I have success! I have gotten new shoots with blooms in the past, but only from the base of the plant. Again, thank you!
