Trees play an invaluable role in our environment, providing shade, beauty and habitat for wildlife. Unfortunately, trees can also become susceptible to pests and diseases – including parasitic plants which draw nutrients away from host trees in order to deplete energy reserves, leaving the tree more susceptible to damage, disease and pest attacks than before. Here are some common parasitic plants you should watch out for and have removed immediately:

1. Dodder (Cuscuta)
Dodder, commonly referred to as the “spaghetti vine,” is an herbaceous parasitic plant without chlorophyll that feeds off tree branches for sustenance and resources, draining vital resources while covering parts of their canopy with thread-like threads of yellow-brown hue. Due to its rapid spread rate and potentially devastating consequences on its host trees’ health, Dodder makes them susceptible to pests and diseases which further threaten them.
Dodder can quickly spread throughout an area and infect multiple trees in quick succession, quickly diminishing their health and diminishing their capacity for photosynthesizing and functioning. Therefore, removal should occur before it becomes an overwhelming problem.
2. Oak Mistletoe (Phoradendron leucarpum)
Oak mistletoe, commonly found on oak trees but also found on numerous other species of trees, is a parasitic plant found most frequently on branches that has green, dense balls of leaves that appear as dense green balls clinging onto branches and may reach three feet in diameter. While mistletoe has become associated with holiday traditions and festive occasions, in arboriculture terms mistletoe can be harmful – stealing away nutrients and water from its host tree, weakening it slowly over time.
Oak mistletoe can wreak havoc with trees by depriving them of essential nutrients they require for survival, leaving their branches more fragile than normal and more prone to breaking or even killing off completely. Therefore, regular pruning and removal must take place to control this parasitic plant effectively.
3. Dwarf Mistletoe (Arceuthobium spp.)
Dwarf mistletoe is another parasitic plant common to conifers such as pines and spruces, typically appearing as small clusters of yellow-orange branches that form dense masses that become spiny over time. While oak mistletoe appears as dense yellow-orange patches of needles with yellow tips that sprout directly out, dwarf mistletoe usually takes on smaller forms that appear as yellow spiny clusters with sharp spiny points on them instead of appearing like leaves growing from tree bark, creating major deformities such as witches’ Brooms–clustered clusters of stunted branches growing abnormally into abnormal formations on trees that become infected over time by this parasitic plant.
Dwarf mistletoe’s damage goes well beyond aesthetics; it saps essential nutrients away from trees, weakening them over time and contributing to severe decline. Dwarf mistletoe poses particularly grave threats during stormy conditions because its plant feeds off essential resources that should stay inside, draining essential hydric reserves away and weakening structures more than usual. This type of mistletoe should be considered particularly risky given that its removal leads to tree decline with structural weakness potentially increasing structural breakage risk in extreme circumstances compared with tree replacement by natural means alone.
4. Broomrape (Orobanche spp.)
Broomrape, another parasitic plant which feeds off trees and shrubs by draining their moisture and nutrients, can often be identified by its distinctive purple or yellow flowers that sprout directly on their root systems. While its infestation sometimes targets certain tree species directly, typically its presence manifests more widely across shrubbery or vegetation instead.
Broomrape may not have as drastic an effect on trees as mistletoe or dodder; yet its gradual presence can contribute to decreased tree health over time. If found near tree roots it should be removed immediately for optimal tree health.
5. Bastard Cress (Barbarea vulgaris)
Bastard cress, an obscure parasitic plant, threatens many tree species worldwide. Attaching itself to tree roots, this parasite extracts water and nutrients from soil over time – eventually depriving trees of essential resources needed for their health if left alone too long. Bastard cress often takes the form of low-growing leaves around its host’s base that make it hard to detect.
As is true with many parasitic plants, early intervention is key in combatting bastard cress infestation. Through regular tree inspection and removal of any infected plants as soon as they appear is the key to mitigating long-term damage from bastard cress infestation.

6. Indian Mistletoe (Viscum album)
Indian mistletoe, while less frequent than oak mistletoe in North America, poses a considerable threat to certain tree species. Like oak mistletoe, this parasitic plant grows clumpily on tree branches with green-tinged leaves and white-fleshed berries for easy identification. Indian mistletoe feeds on nutrients provided by trees leading to reduced growth or potential branch dieback.
Indian mistletoe, much like oak mistletoe, needs regular monitoring and pruning in order to prevent its overtaking of trees. If left unchecked it can quickly spread across landscapes causing much destruction in its wake.
Why Removing Parasitic Plants is Critical
Parasitic plants not only rob your trees of resources, they can also cause long-term harm. Left undetected, they make them more prone to diseases, pests and environmental stresses and ultimately decrease vitality; ultimately leading to structural failure or in the worst-case scenarios, death of trees.
Immediate removal of parasitic plants is critical to keeping trees healthy, and professional arborist inspections should be conducted periodically to detect early and take swift action when they appear.
Detecting parasitic plants on trees should never be left until later; Arbor Wise Tree Service’s expert team at Arbor Wise Tree Service specializes in eliminating them to ensure their wellbeing and longevity for many years to come. They know just what steps are necessary, from identification, treatment and removal.
