Kingsville boxwood help

[MomoBonsai]

Welp I think it’s probably too late, at this point I’m looking for research purposes so I don’t kill another one. Had this Kingsville boxwood several years now, had moss on it always till very recently. Was always healthy till pretty recently. Repot I think in January, I kept the moss as best I could during the repot, can’t remember exactly what soil was in it but more dirt based soil. Think I put bonsai jack premium mix in. Anyway it started greying leaves and not producing anything after a short session of growth early spring. Checked the roots they looked ok, was a little soggy in the bottom of the pot so I removed the soil and put some fresh and sprayed the roots in case I missed fungus or something. I did not root prune. Put it inside a couple days just to keep it out of the heat a bit. Back outside now. Greying is continuing. I’ve removed everything dead. Some branches still have green cambium, others are dead. I had a Japanese boxwood that I gave to a family member do the exact same thing not long after I gave it to her and it didn’t make it. Any advice would be much appreciated. Used to be a beautiful full canopy tree.

Mine was slow to recover from the repot, went from organic to bonsai jacks mix as well. You said you "changed the soil"....how long after the repot was that?

Hard to tell exactly what is happening. Fwiw. I e had Kingsville for decades. They’re pretty tough trees.

A few thoughts:

You basically repotted twice in spring. Even if the second left roots intact. Not a great thing to do.

You’ve used two kinds of soil - one sounded too fine. The other in the photo is too coarse

The moss is incidental and can be an issue since it masks watering requirements

Bringing trees inside is always a bad idea. Bringing ailing tree inside weakens them further regardless of outside weather. Plants don’t like moving around. It require readjusting to changing conditions. It stresses the tree much more than outside weather in Fla.

feb full repot, last weekend check roots/fresh soil. like i said i had a mame tiny one that i gave as a gift do the exact same thing 2 weeks after i gifted it which makes me think its either disease or overwater but i find it hard to believe over water since ive had the tree 3 1/2 years and first time its suffered like this. I do think possibly the soil is too coarse perhaps, but at this point should I just wait to see if it recovers before doing anything else to it

I would leave it alone, maybe put it in a spot with some afternoon shade, and only water it when it needs....I would think about getting a replacement and trying again

I would just let it be for a few months. Keep the soil evenly moist but not soggy. Stop checking the roots. See what happens. Boxwood are slow. Kingsville is slower. Youre expecting too much too soon.
