Missing Willow Farm

Apple blossoms are bursting everywhere on the trees we planted six years ago.  We are really lousy at growing enough apples to actually eat.  We usually only get a few on each tree then deer and insects take them before we can get to them.   This year, we’re hoping to get more apples to start with, so we’re hand pollinating.  I hate the idea of fencing the orchard, but maybe we can put up some fishing line fence if we get a lot of fruit.   Does anyone have suggestions on spraying for bugs?  I think we’re too late to apply dormant oil.
