Here is a first for me! I have tried for I don't remember how many years to flower various Rick Rack Cacti. I could grow large plants, not to ever see a bloom.
This one started to bud outside and didn't abort them during the transition to the greenhouse. Open this morning and it is the Epiphyllum anguliger!
3 more buds in the works.
I always read that people throw banana peels on to the medium. Well, a few months ago, I stood there with a banana peel in my hand and figured, what is there to lose? So, I placed it on the surface for a few weeks. I wonder, was that the trick? Extra K?
