Mistletoe: The Tree Thief and Its Impact on Tree Health

Mistletoe Increase: More Than Just Fewer Ice Storms

While ice storms may physically remove some mistletoe, the recent proliferation relates more to bird populations, host availability, and climate patterns than winter weather alone.

Why Mistletoe Matters

Scientific name Phoradendron = "tree thief." UGA tree expert Kim Coder notes mistletoe-infested trees suffer increased drought mortality. The parasite:

• Roots into bark and xylem
• Diverts water and nutrients
• Weakens branch structure
• Creates entry points for decay fungi

Management Recommendations

• Prune out infected branches (12+ inches below attachment)
• Prioritize high-value trees
• Remove before berry production to limit spread
• Consider professional removal for large trees
