My Phal Experiment! Female
Default My Phal Experiment!

In the winter, I bought some random orchids, and brought them home and immedietly repotted in semi-hydro, and then cut the flower spikes off. I cut the spikes off thinking that the plant would expend more energy taking care of the flowers then on growing new roots.

This is the result of my experiment: All plants thrived. very good root growth. All plants are in spike or blooming. I know this result is due to the experiment and not to my usual care. No plants died during the experiment. These are all the original "subjects."

I have a large dyed phal that will end up being white, a named phal (Talsisco Noble, which bloomed earlier than the rest, so it has only 2 flowers on it now), a small purple Noid, and a yellow green Noid. All had good roots when I bought them. I did not buy any half price from the bargain bin because I wanted to start with good roots.

What I have learned is that cutting off the spike actually does revert the plant's activities to creating roots and leaves. I guess after the shock of transport and so on, the orchid is trying its best to stay alive, and this takes some of the pressure off. True? Not True? I am not a plant expert, but that is my explanation.

These are photos of the experimental plants:
This is all together, you can see they are of different sizes.

Small greenish yellow Noid:

DTPS Talsisco Noble (Sogo Pride X Sogo Splendor) strangely had a tag:

I can't wait for the big white one to bloom. This was one of those blue dyed orchids, and I am hoping it has a little pink in the center. I was told that they actually choose very sturdy white cultivars for this process, so it should end up a very nice orchid.

You will be surprised that these orchid plants can take abuse and still flower beautifully.
You are wise to repot your Phals upon arriving in your environment to check the status of its roots.
I also repot Phals even in spike or in full bloom.

Looking good, glad it's working for you.

What medium are you using? You mentioned Semi-hydro but that uses leca/hydroton (expanded clay pellets) and your photos don't look like that and I can see bits of bark. Over time bark will decay too quickly if kept constantly wet like the S/H technique which is why that uses inorganic clay pellets rather than bark.

Hi. It is lecca/hydrotone with a small bit of choir On top. I live in a very arid place. I had just used some bone meal on top as well For some calcium. It took me an entire year to figure out the amount I would need in the arid wastes of New Mexico so I would not have to water every day.

Out of 29 orchids I have only 2 in bark. The rest is red lava, black lava, hydrotone (with or without semi hydro), or combined lava and hydrotone. Some have a top dressing of small rocks, sand, moss or choir.
