Managing Mistletoe: A holiday tradition yet a tree pest

While mistletoe adds a festive touch during the holidays, it poses serious threats to trees by sapping their nutrients and can also be harmful to pets and humans. Here's how to effectively manage this parasitic plant:

  • Mechanical removal: The most effective method is to physically cut out the mistletoe or remove the infested branches. In cases of severe infestation, removing the entire tree may be necessary. This is best done during the dormant season when trees are leafless. Ensure that the removed branches are disposed of properly and not placed in compost.

  • Plant resistant species: When planting new trees or landscaping in areas prone to mistletoe, opt for resistant tree species. Chinese pistache, crape myrtle, ginkgo, golden rain tree, liquidambar, and sycamore are less susceptible to infestations.

  • Avoid chemicals: Chemical treatments are generally ineffective against mistletoe and can damage the very trees you aim to protect, as well as other plants and the surrounding environment.

Taking prompt action against mistletoe will help prevent its spread and protect your trees from further damage.
