I have a Jiro persimmon (1st pic) and a Stanley plum (2nd pic), which are both 2 years old and first year in the ground. They each have a horizontal or even slightly downward-sloping limb (red arrows). I'm thinking they are going to touch the ground when the fruit weight is added. Do I need to do anything about those limbs? Are they going to get thicker and sturdy enough to bear fruit? Will I be helping them if I stake them or it will just make them lazy?
