Q.Apple Trees
I have planted 3 Liberty, 2 Winesap and 1 Pink Lady apple tree. Will I have any problems with pollination?
Good pollinators for Liberty can be a flowering Crab Tree or a Cortland, Freedom or Starkspur.
Winecrisp works as a good pollinator for Pink Lady.
I do think with the number of trees you have planted, and if you have Bees in your garden
