Hi Al, what I meant by my poorly composed sentence ("But having a strong source of light for 12 hours isn't natural (if they were in a south facing window), so it's interesting how the leaves are showing a lack of light") is under natural light conditions from even a window facing south, a jade plant wouldn't normally receive 12 hours of bright sunlight. So it's interesting how my jade plant leaves, despite having 12 hours of artificial plant light for over a year, started to curl and become thin because they want more light.
Even when I didn't have plant lights and my jade plants were not getting enough sunlight, the leaves were thick. But the branches were leggy (too much space between the leaves) which reveals insufficient light.
You described exactly how I felt the last time I trimmed my jade plants. I had these healthy cuttings and I felt so bad tossing them. So I propagated a few. But like you, I really don't need more jade plants. 😆
I use a liquid succulent fertilizer but haven't lately so I need to resume that. And I will repot the jade plant that's not in a pot with a drainage hole, but should I wait until spring?
I LOVE that adorable photo of the baby jade plant in the acorn cap! Thanks again Al for all your wisdom!
