Once you’re growing a fruit tree, chances are you’ll eventually see problems occurring on the leaves, stems and/or fruit. This series of videos looks at some common fruit tree diseases and insects that affect the most common fruits gardeners grow. Often the best controls are cultural and occur early in the season.
