As harvest approaches for apple trees, it is a good idea to walk around your trees and observe how things look on August 1st. Look at your overall pruning job and take note as to what you should change next year. Is there adequate airflow through the tree? Can sunlight reach all of the fruits? How do the leaves look? And of course the fruit: clean? insect damage? fungal issues? size of fruit?
Each tree has different issues and by observing them individually throughout the season you can address some of those needs pre-emptively next year. Be sure to take good notes in your journal
