Mistletoe 101

Mistletoe isn’t just a single species – it belongs to multiple families within the order Santalales. For those of us in North America, our primary concern is the mistletoes from the Santalaceae family.

There are two main groups to remember: broadleaf mistletoes, which are hemiparasitic and can be native to the US, and dwarf mistletoes, which exclusively parasitize conifers. These plants have specialized roots called haustoria that penetrate host tissues to extract water and nutrients, leading to stunted growth and weakened plants.

Signs of Infestation

When mistletoe takes over your plants, you might notice hypertrophic swelling at the attachment site, witches’-broom formations, and stunted or dead branches. Heavy infestations can weaken your plants, making them vulnerable to pests and diseases.

Management Methods

Appreciation

While mistletoes can be a nuisance, they do have ecological benefits. They support native wildlife, attract diverse species, and have cultural significance. If you have a few plants here and there, consider leaving them be for the time being.

Chemical Control

If you’re ready to get rid of mistletoe, you can use the plant growth regulator ethephon to detach them from host plants. However, be cautious as this can also damage host plants and cause skin and eye irritation.

Mechanical Control

Pruning and manual removal are effective ways to eliminate mistletoe. Make sure to remove infested branches with sterilized tools, and wrap the infestation site to block light from reaching hemiparasitic broadleaf mistletoes.

For severe infestations, it might be best to remove the entire plant to prevent further spread.

Prevention

To avoid future infestations, consider planting mistletoe-resistant species like Ginkgos, Sycamores, and Redwoods. By using resistant plants in your landscape, you can reduce the likelihood of mistletoe taking over.

One Final Reason for Control

Aside from protecting your plants, managing mistletoe can also save you from those awkward forced kisses under the mistletoe. Let love blossom naturally, without any interference from invasive plants!
