I've collected this Acer Campestre in last weekend. I saw this plant for few weeks ago, sombody has cut the upper parts, and broke the trunk. But the nebari is looking good.
It was hard to diging out, because the roots ar crossed with an acacia.
After the collecting i've cut all the roots, that groving under, and the rest of the trunk. I leave only the nebari.
A put the roots full in to the ground. I used a mix half gravel, half compost.
I visioned this bonsai. Maybe in spring will grooving out many new sprout, i need only select.
