Bradford Pear Decline: Natural Lifespan, Not Pine Competition

13-year-old Bradford pear dying from top down under 100-ft neighbor pine. Owner suspects sap/root competition.

Bradford Pear Lifespan

• Average: 15 years
• Structural failure typical after 15 yr
• Crown dieback from top = classic end-of-life

Pine Influence Ruled Out

• Root competition = whole-crown decline, small leaves
• Sap: No allelopathic effect
• Top-down dieback = pear genetics, not pine

Common Pear Diseases

• Fire blight: Dark brown dead foliage attached, starts at twig tips
• Bacterial leaf scorch: Light brown leaves, fall like normal drop

Care Advice

• Don't use fertilizer spikes (root burn)
• Broadcast 10-10-10 at 1 lb/inch diameter
• Pre-rain application

Tree is at natural lifespan end. Fertilization may extend slightly but replacement planning wise.
