Before removing Spanish moss, it helps to understand exactly what it is.

Spanish moss, or Tillandsia usneoides, is not actually a moss at all. It is a flowering plant in the bromeliad family, related to pineapples.
It is an epiphyte, meaning it grows harmlessly on trees, attaching to branches and trunks It does not parasitize or take nutrients from the tree
It flourishes in warm humid climates and propagates quickly. Spanish moss spreads easily when fragments attach to new trees.

While not directly harmful, heavy Spanish moss growth can potentially weaken trees by adding excessive weight and inhibiting light exposure and air circulation.

Why Remove Spanish Moss?

There are several reasons homeowners wish to remove Spanish moss:

It can give trees an unkempt, unruly appearance, detracting from landscapes.
It blocks sunlight from reaching the tree’s branches and leaves. This can slow growth.
Heavy moisture retention makes Spanish moss very heavy. This stresses and damages branches.

Dense moss prevents air circulation, creating conditions ripe for disease and pests.
It provides habitat for chiggers, no-see-ums, and other biting insects.
Some people simply dislike the gloomy aesthetic of draped Spanish moss.

It can spread quickly to surrounding trees, covering everything.

Effective Methods to Kill and Remove Spanish Moss

If you decide Removing Spanish moss is right for your landscape, here are proven methods:

Manual Removal

Physically removing the moss by hand is the most natural, eco-friendly approach.

Use a ladder, pole pruner, or climb the tree to reach moss in upper branches. Take safety precautions.

Wear heavy gloves to protect from irritation. Spanish moss fibers are coarse and irritating.
Gently but firmly pull moss away from branches and trunks. Try to remove entire strands so they cannot reattach.
Spanish moss is extremely lightweight when dry. Remove on a dry day when the moss is not waterlogged.

Expect the process to be time consuming. Have patience and remove methodically.
Persistence is key to thorough removal. Even tiny fragments left behind can regrow.

Power Washing

Using a power washer is faster than hand removal:

Adjust nozzle to a wide, soft spray pattern to avoid damaging bark.
Systematically wash moss off branches, working from the lower crown upward.

Take care not to strip away healthy bark. Keep nozzle 12+ inches from the tree.
The force of water should detach and wash away moss without harming the tree.
Time the power washing when Spanish moss is dry for easiest removal.

Catch and dispose of dislodged moss so it cannot reattach to surfaces.

Herbicidal Sprays

Applying moss-killing solutions is an effective chemical treatment:

Copper Sulfate

As a systemic herbicide, copper sulfate penetrates and kills Spanish moss.

It has antifungal properties that help control moss regrowth.
Use during dormancy to avoid damaging tender new tree growth.
Wear protective gear to avoid skin and eye irritation.

Can cause discoloration on sprayed surfaces. Avoid near houses.

Potassium Bicarbonate

This contact herbicide quickly kills moss on contact.
Safer for tender tree shoots than copper sulfate.
Causes less discoloration or corrosion than copper solutions.

Frequent re-application needed as it does not prevent regrowth.

Baking Soda

Another fast-acting contact herbicide that is safe for plants.
High salt content can potentially burn new growth and leaves.
Avoid contact with grass, flowers, shrubs, and other landscaping.

Also washes off easily with rain, so repeated applications may be necessary.

For large trees or high accumulations of Spanish moss, hiring a professional arborist service is often the best solution.

Licensed arborists have specialized tools and equipment to access and remove moss high in tree canopies.
Professionals know the most effective products and proper application methods.
Crews can thoroughly remove moss quickly without damaging trees.

Experts recognize if the tree is stressed and needs restorative pruning or care.

Monitor trees closely and remove any new strands that appear before they spread.
Apply tree-safe moss-inhibiting products. Consult an arborist for recommendations.

Improve air circulation and light exposure with selective branch pruning.
Promote tree vigor through proper watering, fertilization, and pest management. Healthy trees resist moss.
For heavier moss infestations, plan on yearly maintenance removal to keep the problem controlled.

With persistence using these removal methods, you can successfully rid your trees of unwanted Spanish moss and restore their natural beauty.

What is Spanish Moss?

Spanish moss is not from Spain. Spanish moss is not a moss. Go figure. It is a bromeliad and in the same family as pineapples. Whatever you do, don’t start adding it to your pizza (please, it’s gross and not edible). Despite common misconceptions, Spanish moss is not always harmful to your tree. They aren’t absorbing nutrients or feeding on your tree, instead Spanish moss indirectly damages a tree. Spanish moss takes in a lot of water, which makes the branches heavy. Older branches can use a lot of string. Not to mention the moss can cover leaves, blocking light and slowing the trees growth rate.
