Doll says that the fall is good timing for boron and zinc foliar treatments.

“If you do it now, you won’t have to do it in the pre-bloom timing,” he says.

A fall application of boron, in particular, is more effective, because the leaves are still on the trees—meaning the tree gets more of this micronutrient because it has a larger treatment surface.

Other post-harvest chores 

Walking through orchards to scout for pests and disease post-harvest is important as well.

“For example, if we see rust on the leaves, we would want to apply zinc sulfate to knock the leaves off of the tree and get that rust inoculum on the ground, where it will break up,” Doll says.

Applying 30 pounds per acre of zinc sulfate to drop leaves is recommended in late October to early November, he says.

Scouting orchards during this period can also reveal irrigation issues that may mean repairs or that irrigation systems need to be moved to be more effective.

Doll recommends says this post-harvest time also is an ideal time for pruning, if needed.
