Mulberry Tree Top Dieback: Investigating Branch-Level Issues

Non-Fruiting Mulberry with “Burned” Upper Canopy

Two fruitless mulberries show green lower leaves but upper canopy looks fire-scorched. Hot climate, but never happened before.

Diagnostic Steps

  1. Inspect affected branches for borer holes, cracks, or cankers at base of dead wood.
  2. Check leaves for spider mite stippling or fungal spots.
  3. Scrape bark on dead vs. live branches—green cambium = alive.

Likely Causes

  • Borers girdling upper branches.
  • Verticillium wilt (vascular fungus) moving up.
  • Root issue affecting water delivery to top.

Report findings for targeted treatment. Prune dead wood back to live tissue.
