Sweet, fallen fruit will also attract critters passing through, which could lead to damage to other crops. The rotting blueberries may also attract yellow jackets that nobody wants that!
In areas with particularly cold and long winters, extra protection may be necessary. To protect from harsh winds and heavy snow, stake the centers of your blueberry bushes to avoid breakage.
Four to eight inches of mulch can be applied around your bushes. Pack it snugly but not so tight that the roots can’t breathe. Mulching will help maintain the pH of the soil and retain moisture.
