Hello! I grew my jade from leaf propagation. It’s about 5 years old. The main trunks of my plant are not growing up but out, horizontally. It puts out tons of robust leaves and aerial roots along the stem.
-Do I stake the main stem? And prop the others up?
-Can I cut this way back to encourage upward growth? Or do I just trim back the leaves and branches?
-Is this from not having enough light? Or is it in too deep of a pot?
The blue spots are from a copper treatment I recently applied to kill mold. There was a string of turtle hanging above it that had been dripping on it and caused some of the leaves to mold.
Thanks for your help!
