There are 28 trees on the property - all Stark's Dwarf Supreme. They were planted in 2008-2010, given their tree pellets, and fenced for rabbits. These are primarily peach, nectarine, apricot, paw-paw, and plum trees. I live in Minnesota (lower part of zone 4). All trees were rated for this zone.

These trees have been in the ground at least three - five years.
Each year - for the past 3 years, they have bloomed profusely, grown somewhat, and each year they have lost ALL their blooms and most of their leaves. This year several of the trees lost ALL their leaves. Has anyone ever had this happen with their Stark trees?

Considering the cost to set this up initially, I won't be replacing any.from Stark.
Does anyone have a idea what could have happened to two rows of trees?
