RE: Virus in hosta

Thanks for the info all.

The wood and branches were easily hauled away, it's the sawdust that
concerned me.  I'm not quite so willing to vaccuum the garden beds.
I'll cross my fingers and hope all is well.  All hosta have to be moved
in spring as there will be no shade in that corner of my world any
longer.

Yes there will be new trees and the like planted there, but not enough
to cast enough shade.

I believe that Dutch Elm disease is a fungal, not viral. The fungus
growth
itself blocks the transfer of water in the plant. May be splitting hairs
here, but it seems that the only host seems to be they zylem of elms.
BUT, for those of us still growing elms, and in here in Michigan, Ash
and
oak trees.  The wood, is considered 'contaminated'.  In the case of
Elms,
the fungus is in the zylem, but it 'fruits/spores' on the bark which can
then be spread, ditto Oak wilt disease.  In some cases we are required
to
have the wood removed immediately (cannot store and burn) to approved
disposal sites which will burn the wood to eliminated the possiblity of
spread.
