Thanks for the response! The ideal photo you shared for the even shape and care is definitely what I would like to see. I’m concerned the tree we inherited isn’t in the best of health, but I would like to see that change however possible.
The video you shared was excellent. My main concern is that the “left” side of the tree is clearly less dense and currently has several dead branches. That’s readily evident now that it’s flowering. Pruning that side further, although it needs it, will exasperate the lack of balance even further. This is why I wondered if the healthy side should also be trimmed back to help even it out the aesthetic.
@LibertyLizard indicated in another comment not trim back the healthier part unless stability was the concern. I wouldn’t call it “unstable” based on the ground space and roots, but the trunk isn’t entirely vertical and leans a bit towards the fuller side. Not sure that would classify as a “stability” issue though. It’s not yet a dense tree.
I will check the soil this summer and water as needed as you suggest. Would you suggest anything else, perhaps certain kinds fertilizer, to help the tree?
When you said, “Leave it alone for now and then go for it in early spring.” Do you mean next year? Or next month? The photos were taken the day of the post. It’s very nearly “officially” spring and the tree is blooming.
