I love cherry jam, pie or cherry anything so much I planted 4 trees about 30 years ago. 2 genetic dwarf Royal Annes which were said to top out at 12 to 15 feet, but are now over 30 feet tall. Between them I planted.a 4 in one to assure pollination but the deer broke off two of the grafts. The fourth one is a compact Stella, which is a self pollinating sweet cherry. In those 30 years we’ve had maybe one pie and several hands full. The crows don’t even wait for them to get ripe!
