Reduces Risk of Disease
Heavy flowering can lead to dense clusters of leaves and branches that trap moisture and block airflow. That’s the perfect setup for fungal diseases like powdery mildew, blight, or canker to take hold. By thinning out crowded areas, you let in sunlight and fresh air that naturally keep pathogens at bay.
This is especially important for trees like flowering cherries and plums, which are prone to fungal issues in damp or humid weather. Pruning also helps you spot early signs of disease or pest infestation before they spread. If you’ve ever seen a blooming tree suddenly drop leaves or ooze sap mid-season, you know how important it is to catch these problems early!
