My perrenial gardens did not have a good year for some reason -
some say it was because we did not get the usual snow cover
in winter. I have had several different types of plants this
year look great and I'll go out one day and half the plant is
wilted and then dies. It has not happened to all plants in
the same beds. Very sporatic throughout. At first I thought of
voles or moles but no other plants have suffered beside these
half dead plants. Any ideas? there has been no effidence of
anything eating leaves etc.
