Hello! I am an avid grower of various crassula and kalachoe with a handful of echis also in my collection. I have been growing under lights (new englander) year round for almost six years. My plants are under lights and against my tiny south-east window.
Last September I picked up a ~5" tall Pachypodium Lamerai. (please note my lights run for 11 hours a day so there no winterizing here lol) At first I placed it on the "lower" shelf with my Kalanchoes and bright-light crassula... New leaves were visibly smaller over the three month so I moved him up by the echis to the brightest spot on my upper/brighter shelf. So far in just two weeks, new leaves are already bigger than the last set.
I was watering every 10-14 days with my larger jades. Since the lighting boost, the plant has consumed several lower/eldest leaves, they slowly yellow/crisp off. the pot is bone dry after ~7 days so I started watering when dry instead of waiting til seeing visible need for water (lower trunk would start to shrivel).
Now after three weeks of weekly water and increased light, there are thick fresh white roots coming out of the bottom of the pot! This pachy was in a 3"x2" plastic nursery pot when I got it, been in this 5" terracotta one since I brought it home.
What is advice for watering this patchy? When dry or after significant period of drought?
Should I consider repotting?
