apple trees bench grafted this spring

apple trees bench grafted this spring. high density maybe 6” centers in 3 x 20 ft bed. Most are around 2 ft and they were transplanted in may after the ground thawed, we had snow until mid april, short season here. I keep these under hoops with netting to keep our curious deer who would see it as a salad bar, also rabbits. one hoop covers 2 rows so it’s easy to duck under and use the path to work between them.
