I grew this tree from seed almost couple years now and I’ve pruned it a couple times over this years due to leaves crisping and dying off but recently the branch tips have been turning black. There’s also leaves that look like they’re about to bud on the branches but they never pop out. I moved to San Diego a few months ago and I assumed it would like the weather more than Northern California, so I’m not sure what the real cause is. It has a lot of sentimental value so if there’s anything I can do to save it I can. Thanks yall!
