Mistletoes are parasitic plants that grow on trees and large bushes, causing damage or simply being ugly. Broadleaf mistletoes, also known as leafy mistletoes, are distinguished by their green stems and broad, nearly oval leaves. Mistletoe plants grow into spherical shrublike clusters that can grow to be 2 feet or more in diameter. In the winter, evergreen clumps of mistletoe can be seen on deciduous trees. It is not necessary to distinguish between leafy mistletoe species for management purposes. In this artical we will learn about how to remove mistletoe from trees?
Mistletoe Should Be Removed Before it Harms your Tree
Mistletoe saps water and nutrients from its host tree, effectively draining its resources. This weakens the tree and makes it more vulnerable to additional stressors like drought, pests, and diseases. Mistletoe infestations can cause slowed growth, branch dieback, and overall tree vigor loss over time.
Mistletoe has the potential to disturb the tree’s natural physiological processes.
It has the potential to disrupt the tree’s growth patterns, resulting in aberrant branching and deformation. As a result, weakening branches are more likely to break during storms or high winds, providing a safety threat.
Mistletoe spreads by producing berries that are eaten by birds. Birds then deposit the seeds on neighboring trees, allowing mistletoe to spread throughout a forest or landscape.
Pruning of mistletoe trees
Pruning mistletoe-infested trees is a vital step in managing and reducing the impact of mistletoe on the host tree’s health.
Tools and Materials:
- Pruning shears or loppers
- Hand saw (for larger branches)
- Gloves
- Safety glasses (optional)
- Ladder (if necessary)
- Trash bags or a container for the removed mistletoe
Steps
- Locate the mistletoe-affected branches in your tree
- Prune them in a dormant season typically in fall or winter because the host trees are nonactive this season
- Remove the affected branches with pruning shears. Remove the mistletoe few inches below the place where it joins to the host branch. To avoid tree damage, make clean, accurate cuts.
- If mistletoe has infested bigger branches, remove those branches using loppers or a hand saw. Do not damage the tree’s primary structure by cutting several inches below the mistletoe attachment point.
- Collect all of the mistletoe that has been removed and place it in a plastic bag or container. To prevent the spread of mistletoe seeds, dispose of them by burning or throwing them away.
- Inspect your tree for mistletoe regrowth on a regular basis and repeat the pruning process as needed. Mistletoe can reappear, so you must be careful.
- If the mistletoe infestation is severe or the tree’s health continues to deteriorate despite your efforts, get professional advice from a qualified arborist or tree specialist.
Chemical control to remove mistletoe
- Chemical treatments include spraying mistletoe with certain herbicides. This strategy can be useful for severe infestations that cannot be properly trimmed.
- Consult a professional arborist or a local agricultural office for advice on selecting and applying the right herbicide, as mistletoe species and tree types may require different treatments. When using herbicides, always follow all safety measures and local legislation.
- In chemical treatment herbicides are applied to remove mistletoe from trees
- The plant growth regulator ethephone is used to remove mistletoe from trees
Mechanical removal
Scrape or cut the mistletoe off the tree using a brush tool
This method is useful if the mistletoe is not completely embedded
Remove all visible mistletoe to prevent regrowth
Reducing host tree stress
Mistletoe is more prone to infest stressed or weakened trees. Focus on preserving the general health and vitality of your trees to avoid mistletoe infestations in the first place. Proper watering, fertilization, and regular tree care can help lessen mistletoe susceptibility.
Prune the nearby trees
Mistletoe can spread from tree to tree, so if you have multiple trees in close proximity, consider pruning or removing mistletoe-infested branches from neighboring trees to prevent seed spread.

What are the harmful effects of mistletoe on trees
- It sucks nutrients and water from the host tree which weakens the host tree and disrupts its normal growth
- Mistletoe can cause dieback of branches where it is attached
- Infested branches may become weakened and more susceptible to breakage during storms or high winds, posing a safety hazard.
- The presence of mistletoe can disrupt the normal growth patterns of trees. It may lead to the development of abnormal branches and deformities in the tree’s structure, which can affect its overall aesthetics and stability.
- Mistletoe infestations can negatively affect the aesthetic value of trees, particularly in landscaping and urban settings. This can lead to reduced property values and increased maintenance costs.
What is mistletoe, and why should I remove it from my trees?
Mistletoe is a parasitic plant that can weaken and harm host trees by draining nutrients and water. Removal is essential to maintain tree health.
Can I simply pull mistletoe off the tree by hand?
Pulling mistletoe by hand may not effectively remove the entire root system, making it likely to regrow. Pruning is more effective.
Are there any chemical methods for mistletoe removal?
Yes, Ethephon, a growth regulator, can be used to encourage mistletoe abscission. Consult a professional for proper usage.
Can mistletoe grow back after removal?
Yes, mistletoe can regrow. Regularly monitor your trees and repeat the removal process as needed.
Conclusion
Understanding how to remove mistletoe from trees is critical for preserving the health and longevity of your prized trees. Although mistletoe is commonly connected with holiday customs, it can be damaging to trees, causing nutrient and water drainage, decreased vigor, branch dieback, and increased exposure to pests and diseases.
