I tried to keep them cold, but above freezing. Apparently, they just wanted to wake up. What I thought were flower buds, are actually leaf buds, but the flowers are starting now too. I gave up and moved them into the house and into my southern exposure with lights.
Best of luck with this. I know we both got ours from Brent this year, but was checking mine this morning and no signs
of movement yet. I've kept mine outdoors out of any sunlight mulched well under my sun room.
Our Winter probably more mild than yours this year? but did have near 0º with that cold Arctic blast in January.
I was checking mine to consider re-potting prior to Spring movement per Bonsai Empire species care guide...
As to moles/voles, I 1st spread granular MoleMax on the ground in my "bonsai cave" then mulched well
around all my pots, then a second application on top of everything of the MoleMax.
I also used a granular lawn insecticide with the MoleMax stirred into the mulch. So far no damage this year
even with the loss of the outdoor cat that always left us mole trophies to step on just outside the entrance door.
Hope next year fairs better for weathering. Could be the difference in climates from recent years care to current Winter
that caused the early movement. Like it was predestined to occur having been raised in California.
I think next year or two may possibly change this in your favour, hoping anyway.
