help clematis is dying
hi, im a first time poster on this forum. im looking for information for my mom. 2 of her 5 clematis are dying from the groud up and she doesnt know why or what to do.
they were planted last year. she lives in zone 4, they were planted with a large hole backfilled with compost and good soil and planted with the crowns below ground level.
im sorry, i dont know the names of the ones dying, or even if they are the same type. the stems are turning brown and dying at the base of the plant then travelling up to the ends.
ive done an internet search but im getting too many possibilities and hoped i could get some suggestions from this group. thanks in advance.
