Susan, Oh, Oh. That sounds like what has been happening to my tree, one
section at a time. The wilt affects the main roots, but not all at once.
The infection may spread slowly over a period of years or over a short time
span, but I don't think they die all at once. A tree will bloom or leaf out
on stored energy from last year but because the Phloem sp? (transport cells)
have collapsed, there is no way to get food & water to the stems and
branches, so the leaves wither and die. OSU extension says that
Verticillium is in our soils everywhere and your tree either has natural
resistance or it doesn't. Excellent drainage is a must and may stave off
the disease for many years. There is a soil fumigant that can be used, but
what's to prevent rain water from washing the Verticillium back into your
location? The person who comes up with a "cure" for this one will have the
world beating a path to her/his door. I believe she would have to have her
soil tested to make a definitive diagnosis. She has my sympathy! Marilyn

Marilyn, how does one identify that a Japanese maple has died from this? My
mom has had a BEAUTIFUL one in her front garden and it did leaf out, but now
the leaves look like they were fried by the sun.
