I would go light at first and wait and see how they react to it. An issue I always have to be careful of is that I have blueberries and huckleberries planted around most of my pear trees, and they really, really don’t like salinity. That means I can’t apply the salts very evenly but only around parts of the drip line away from berry bushes. I gave each tree a couple to three hands full around the drip line early this spring. Where it was one hand full or several depended on how big the tree was. Today I added a little more because it’s supposed to rain tonight and all day tomorrow. I will probably lay off for the rest of this year and do the same again next year. but we will see how the trees respond to this second dose in a few days. God bless.
