Beware of Mistletoe: A Parasitic Threat to Your Trees

December 21, 2023

Beware of mistletoe in your trees and shrubs—these parasites live off their host, being filled with tradition and history. Druids believed mistletoe protected loved ones from evil, while ancient Greeks used it as a medicinal cure. Today, mistletoe remains a symbol of Christmas romance. With thousands of mistletoe species worldwide, growing on every continent except Antarctica, these parasites form shrubby clumps on living host trees, stealing water and nutrients. While they can obtain some nutrition through photosynthesis, mistletoe primarily relies on "stealing" from the host. A few mistletoe plants on a large tree might not be harmful, but a heavy infestation can impact the host tree's thriving ability. As mistletoe competes for essential resources, the host may lose leaves in the upper crown. To prevent damage, it's crucial to completely remove mistletoe from the host tree, especially before winter fruiting. Consider taking action if you spot this parasitic plant in your trees, and remember to reach out to Gregalls Tree Service for your Tree Service needs.
