ficus microcarpa 'tiger bark'

5 MO Acquired

I have a ficus microcarpa stump that I chopped back a few months ago, it’s not sprouting any shoots nor suckers. I could see some whitish callous tissue though on one of the ginseng like roots when i excavated the soil a little bit; which tells me it’s creating new roots. Any thoughts on why...

Picked this up at Home Depot this spring. Repotted it and did an air layer on it in the spring (already harvested). Wired it today. Got some moist sphagnum around the base of the trunk to try to encourage it to grow some banyan style exposed roots.
