J. maples are great to work with : grown from seeds, cuttings or air-layers, they're a very resilient species.
I have this one grown from a seed collected on a tree that was planted on the side of a street, I collected several from lace-leaf specimens (green or red), but when this one germinated, it was very close to the plain Acer palmatum species. I didn't like the shape so much so I decided to air-layer the top for a double-trunk that i still have and which is not as good as I thought it would be, and kept the lower part.
August 2013 :


It developped well. December 2014 :

But there was a problem with the base, so I air-layed it just above the dead roots :

In June 2018, it began to look nice again :

... but the pot was too small, and in the heat of the summer, two days without watering and I thought if was the death of him.
I had to cut off the dead leader and a couple of branches, and I repotted it in a more "comfortable" (ugly) pot in March.
In April, it looked about OK :


Close-up of the cuts :

Today, it looks promising again. I wired the new leader which was going a bit backward and I'll let it grow, at least until next spring. This hybrid, or chimera, or whatever it can be called, has leaves a bit smaller and more serrated that the other plain A. palm. I have.

Morality :
Never give up on a Japanese maple.
One of the best species for beginners, a very resilient tree, a lot to learn with them.
