Didnt look to see if this was suggested already or you tried this.
You could try gently poking holes in the soil with a screwdriver or similar tool. Also gently scrape the top layer of soil off if it's clogged and replace with new soil. Be careful not to pull roots doing this. A chopstick or similar tool works well for this. I typically look at all my trees in the spring when I take them out of the cold frame and clean the top layer of soil if I'm not repotting them.
I’ll do that!
