Sharps pygmy wilting

[Seraphim01]

To me this represents an ER job.

Best ER root treatment I‘ve used to date that actually worked was 3% H2O2. I soaked the whole mess for a couple minutes, removed the rotten roots, tossed the media, then soaked what was left again. Probably could skip the first flush, but that’s what I did. Quick flush. Replant in new media, or in the ground. Warning Maples are pernicious once they are infected.

Your tree, your call.

Good Luck!

Looks like a classic case of overpotting. How huge is that pot?

Young Japanese maples are extremely susceptible to overpotting. Especially when it's damp and cold outside.

Yup, the rock I was using was a bug one and didnt fit into any other pot so I decided because I'm vewy smawt was to use a big pot so that I could fit the rock into it...lol...so I was basically more focused on the rock than the tree. Big mistake....I should have known better because I've set up root over rock many times. And they are all fine.
