Spanish moss, also known as Tillandsia usneoides, is an epiphyte that commonly grows on trees in warm, humid climates. While Spanish moss doesnt directly harm trees, heavy infestations can become unsightly and may indicate an unhealthy tree.
So, how to remove Spanish moss from tree? You can try to manually remove the strands by raking or pulling the moss off branches. For more effective and longer-lasting control, apply chemical moss killers, horticultural oils, or make environmental changes to discourage regrowth.
If you want to learn more about removing Spanish moss from your trees, here are 5 effective methods to try:
Spanish moss is a common sight hanging from trees in the Southern United States While beautiful, this plant can cause problems if left to grow uncontrolled Read on to learn effective methods for killing Spanish moss and keeping it from coming back.
What is Spanish Moss?
Spanish moss, whose scientific name is Tillandsia usneoides, is not actually a moss at all. It is a flowering plant in the bromeliad family. It gets its name from its wispy, hair-like tendrils that drape from trees, giving the appearance of moss.
Native to Central and South America, Spanish moss found its way to the Southern U.S, where it thrives in the warm, humid climate It grows on the branches of trees but doesn’t take any nutrients from them. Instead, it gets water and nutrients from the air and rainfall.
Why Kill Spanish Moss?
While Spanish moss can add atmosphere and charm to landscapes, it can become a nuisance when left unchecked. Here are some of the main reasons homeowners seek to get rid of Spanish moss:
-
It blocks sunlight from reaching the rest of the tree, which can hinder growth The weight of water-logged moss can also break branches
-
Provides shelter for pests like mites, roaches, and rodents.
-
Traps moisture against the tree, promoting rot and fungal growth.
-
Gives an unkempt, unruly look. Most homeowners prefer a tidier landscape.
-
Steals nutrients and moisture from the tree (this is a myth – Spanish moss is epiphytic and doesn’t harm trees).
-
Indicates an unhealthy tree (another myth – Spanish moss will grow on any tree and isn’t necessarily a sign of problems).
How to Kill and Remove Spanish Moss
Killing Spanish moss takes effort and diligence. Here are effective methods for getting rid of moss and keeping it from returning:
Manual Removal
The only guaranteed way to thoroughly remove all Spanish moss is through manual labor. Follow these steps:
-
Use a ladder, pole pruner, or rake to dislodge the moss and pull it out of the tree. Removing it by hand works best.
-
Going through the tree branch-by-branch, strip off all traces of moss you can reach. Removing it fully is key.
-
Gather up fallen moss on the ground so it can’t reattach or blow back into the tree.
-
Dispose of the moss properly by composting, trash pickup, or burning (check local ordinances first).
-
Inspect the tree every week and remove any new growth before it spreads. Persistence is vital.
Manual removal is time-consuming but highly effective. Just be aware that you’ll need to keep checking the tree and removing any new moss as it appears.
Herbicides
For large infestations, herbicides provide chemical assistance in killing Spanish moss. Three types commonly used are:
Copper-based herbicides – these contain copper sulfate and are effective systemically (absorbed by the plant). However, use with caution as copper can harm the tree if over-applied.
Potassium-based herbicides – Potassium bicarbonate products act as a contact herbicide, killing moss quickly. Safer for trees than copper products.
Baking soda – Another fast-acting contact herbicide that is safe for trees. Dissolve 1/4 cup baking soda in 1 gallon of water and spray on moss.
When using herbicides:
-
Wear proper protective equipment like gloves, long sleeves, pants, goggles, and a mask.
-
Follow all label instructions carefully regarding dilution rates and safe application methods. Never over apply.
-
Remove as much moss as possible by hand first to limit herbicide usage.
-
Avoid getting herbicides on grass, other plants, siding, cars, etc. They may cause damage.
-
Spray moss still attached to trees as well as fallen moss to prevent re-growth.
-
Repeat applications as needed until moss is gone. Be patient, it takes time.
-
Monitor the tree for any signs of damage like dead leaves and cease use if harm is noticed.
Moss Prevention
Once you’ve succeeded in removing all visible Spanish moss, here are some tips to help keep it from returning:
-
Maintain tree health with proper fertilization, water, pruning, and pest control. Moss thrives on struggling trees.
-
Increase sunlight to interior branches by selective pruning and thinning. Moss likes shady, dense canopies.
-
Remove any nests, debris, or other organic matter from tree forks and crotches where moss gains a foothold.
-
Discourage moss growth by regularly washing off branches with a high-power stream of water.
-
Apply vinegar or lime sulfur sprays to make the bark less hospitable to re-growth.
-
Remove any standing water and improve drainage near trees. Moss spreads easily in wet conditions.
With persistence using both removal methods and prevention strategies, you can rid your trees of Spanish moss and keep it away for good. Just be patient and don’t let your guard down.
When to Call a Professional
For homeowners with large properties or many infested trees, getting help from a professional may be wise. Companies like tree services or landscapers have the specialized tools and training to remove moss efficiently.
Professional assistance is recommended if:
-
Trees are very tall, requiring ladders, scaffolding, cranes or bucket trucks to access the moss. Work at great heights can be dangerous.
-
Thick moss growth makes removal by hand excessively difficult and slow.
-
Powerful sprayers are needed to apply solutions high up and fully coat large trees.
-
Tree health is declining and professional diagnosis of any problems is desired.
-
Liability insurance is required if working around homes, power lines, or valuable landscaping.
A certified arborist can create a tailored Spanish moss control plan while keeping your trees as healthy as possible. For most homeowners, hiring help for large infestations can make the process easier and safer.
Killing Spanish Moss Takes Patience and Diligence
While it can be frustrating to deal with, Spanish moss can be successfully removed from trees with consistent effort. By combining manual stripping, herbicide applications, and preventative care, you can reclaim your landscape and refresh the look of your trees. With persistence and vigilance, you can eradicate Spanish moss for good.
How to Remove Spanish Moss from Tree? Use a Power Washer
Power washing is an efficient way to blast off Spanish moss from trees. The strong water pressure washes away the moss without harming the tree.
To power wash a tree:
- Use a power washer with at least 2000 PSI. Gas-powered washers work better for larger jobs.
- Adjust the nozzle to a wide fan spray pattern and keep the nozzle 6-10 inches from the tree to avoid damaging the bark.
- Start at the bottom and work upwards methodically around the tree. Aim at clusters of moss to dislodge them.
- After power washing, inspect the tree and manually remove any leftover debris.
Power washing reaches high branches and removes moss down to the bark surface. But like manual removal, moss can regrow after power washing alone.
Manually Remove the Moss
The simplest way to remove Spanish moss is to manually pull it off the tree. This works best for smaller trees or lightly infested branches that you can reach.
To manually remove the moss:
- Use a rake, broom, or other tool to dislodge the plant from branches. Rake upwards from underneath to gather and remove strands.
- Wear gloves to protect your hands from irritating particles on the moss.
- Work systematically around the tree to ensure you get all the moss. Check higher branches that you cant reach from the ground.
- After removing the main strands, go back and pick off any remaining bits still clinging to the bark.
Manual removal quickly gets rid of surface moss, but regrowth often occurs unless you remove all vestiges of the plant.

Potassium. A spray made with potassium bicarbonate works quicker than Copper sulfate, as it is considered a “contact killer.” It will destroy the Spanish moss without hurting your tree and can also be used on roofs or decking. Homeowners may prefer it to Copper sulfate as it does not stain or damage surrounding plants.
What kills moss instantly?
- Just mix equal parts vinegar with water and load it into the sprayer.
- The moss should die within a few hours and you can easily remove it with a scrub.
- Homemade moss killer consists of four ingredients: water, vinegar, salt and soap.
What is the fastest way to kill Spanish moss?
Copper is the slowest solution, but it is the most complete. As a systemic spray, it is considered effective in attacking and killing Spanish moss. However, copper-based sprays can damage tender tree growth, and any overspray can become potentially damaging to the surrounding landscape.
Does copper sulfate kill Spanish moss?
Although copper sulfate does not kill Spanish moss directly, do not apply it to trees in spring when new leaves and buds appear on the branches as it can kill the new growth.
What is the best fungicide for Spanish moss?
This includes fungicides made from copper sulfate, calcium hydroxide, and potassium. This valuable potassium source (potassium) can contain as much as 10 percent potassium and 1 to 2 percent phosphorus. This is also quite effective in the fight against Spanish moss already established and in preventing new settlements.
