I have Fukai ana Fukuzumi. A smidge rootbound but when I look under the rootball in the middle....I have a few circulars inside the canopy. To be expected I suppose when it's lived in a pot up to 7G size.

I don't plan to bonsai this but it will be grown in native soil.....

Here posting on the Bonsai forum as I suspect many more here are more familiar with JWP-JBP roots.

What time of year would you say is best to do root correction.

Full Dormant Middle of Winter of more like right about when it's about to break dormany in late February.

If if I do root correction, I should *AIM* to really touch 1/4 of the plant or the like since there is some fugi relationship to it.

By coming out the circulars in the middle of the plant, there is a possibilty a good amount of the potting medium might come off. It's still fairly -loose- within the current rootball I have received.

Advice. Don't want to shock it to death is the obvious ask
