Pruning Red Tip Photinia: Avoid Shearing to Prevent Leaf Spot

The History of a Southern Staple

Thirty years ago, red tip photinia (Photinia × fraseri) was the hedge of choice across the Southeast. Winter shearing produced brilliant red spring growth—but also created a monoculture that invited Entomosporium leaf spot. The fungus thrives on tender new leaves, causing purple lesions, defoliation, and eventual death of millions of shrubs.

Correct Pruning Strategy

• Never shear. Shearing stimulates a flush of susceptible new growth.
• Prune selectively in summer. Remove individual limbs with hand pruners or loppers; dry summer conditions inhibit the fungus.
• Accept a looser form. Healthy, unshorn photinias remain disease-free for decades.

If leaf spot is already present, fungicides (e.g., Immunox, Fung-Away) can suppress it for a season or two, but cultural change is the only long-term fix.
