After watering this morning and examining my leptotes bicolor, I thought I'd take another look online at information.
I had looked at the AOS site for care and culture at
Leptotes. It's good for information on how to raise and care for the plant.
Looking at Travaldo's blog at
Leptotes bicolor care and culture | Travaldo's blog, I found a statement under
Substrate, growing media and repotting: that says, "The newly-fixed plants sometimes need up to a year or even two to stabilize." This seems to be in reference repotting the plant, though I could be reading it incorrectly.
When I first received the plant about 4 months ago (first picture), it was seemingly just sitting on top of a pile of orchid bark in a small pot. The roots looked iffy, at best at that time, so I just let it rest in its new home and watched for growth. Unfortunately it wasn't stable sitting on top of media and seemed to be declining. The second picture is of the plant right before mounting. Whatever roots were there before were damaged at that point. The mounting was to stabilize it and allow it to spread out. The third image is the mount 2 months ago. There doesn't seem to be a lot of change in 2 months ... but there's not decline, either (some new growth).
One last place I found that may be helpful: J&L orchids blog post, Spotting the differences in a Leptotes bicolor at
Spotting the differences in a Leptotes bicolor. - J&L Orchids. The images give
some direction on identifying new growth and new spikes which could be helpful.
I hope this is helpful information. As always, I learn something when I share, so thank you for your question.
