Why do some branches die on my fruit tree while others don’t?

Sunlight Competition – Branches deep inside the canopy may not get enough light, so they weaken and die back.

  • Nutrient Flow (Girdling or Blockage) – If part of the tree’s vascular system (the “plumbing” that moves water and nutrients) gets damaged by pests, disease, or injury, certain branches may be cut off from resources.

  • Pruning & Growth Patterns – Fruit trees naturally shed weaker, shaded, or crossing branches to focus energy on the strongest growth.

  • Disease or Pests – Fungal infections (like fire blight) or boring insects may target specific limbs, causing dieback.

  • Weather Stress – Frost damage, heat stress, or wind breakage can injure certain branches more than others.

  • Age of the Branch – Older wood is often less productive and may naturally decline as the tree puts energy into younger growth.

🌳 Healthy Tip: Regular pruning, watering deeply but not too often, checking for pests, and ensuring good airflow all help keep the tree balanced and prevent random dieback.

🌳🍑 Dead limbs aren’t just ugly—they steal energy from your fruit! Call Tree Toppers to give your tree a clean, healthy start.
