When I purchased my T. hildae, I was not able to find a lot of info on the web.
I read where it can be grown like an air plant without soil, but I never saw a picture that way.
This is the way I'm growing this plant, without soil.
When I purchased the plant.
August 2020
It continuously was declining in my care. I finally reached out to where I purchased the plant for some info.
June 2023.
Today
It has definitely come around.
Here is the big thing I learned when I talked to the seller.
I asked how they water there plants. I was told by a sprinkler system. I asked if there was water in the center of the plant and they said yes.
The way I was watering the plant was to dunk it in water for 15-30 minutes. I then treated it like an air plant. I turned the plant upside down for a half hour or so to get all the water out of the center of the plant so it would not rot.
I'm now growing this plant like a bromeliad. I put water in the center of the plant twice a week.
That seems to be the secret to grow this plant.
