Fraxinus older than 4-5 years here...
ARE ALL GONE!!!
DECIMATED... everywhere.
WI DNR (and private activists) had tried for like 7 years, very aggressively to control the beetle. It was a losing game... In the end, we just had to sit back and remark, "FINE!... just TAKE all our ash trees."
The green and white fraxinus that grow locally are even MORE of a pain, in my opinion, for bonsai-goals. I tried for 2-3 years and could not get the responses or behavior I was looking for. I still DO have the tree through.
Got me thinking about "saving" some saplings and growing them, miniaturized, but naturally in containers.
Simply for preservation's sake, for the emerald borers do NOT go after "small' trees.
(It was ROUGH "falling in love" with this tree AT THE SAME time as finding out it has died.)
