I planted 2 apples and 2 plums at about the same time this
Spring. They are all within 50 feet of each other. The plums
are thriving and the apple trees really look pitiful. I
fertilized them the same and tilled the soil in an 8' circle
for all 4, mixing in some mulch and sand. The only difference
is that I think I had a little bit more mulch when I planted
the plums. Since the conditions and sunlight and soil are the
same, what could account for the difference?

Are the apple trees appropriate for your area?
