Why A Wood Fence Turns Green


Green algae, mold, or mildew are usually blamed when a wooden fence takes on a shamrock hue. Wood fences that have become green may be cleaned using a power washer, a scrub brush, or simply being replaced.


A sealer, treatment, or paint may stop a wooden fence from becoming green over time. Such treatments may reduce the likelihood of microorganisms colonizing the wood's pores. Wood that has already become green may be repaired by scouring, sanding, and priming. Painting, treating, or sealing the fence is an option after all the vegetation has died.


Why Is My Fence Turning Green?

Microscopic organisms use the wood's organic components as a food source. Because of its porous structure, wood provides a habitat for microbial life as it absorbs and stores water. The growth that begins on the fence might spread to the house's siding and eventually the inside.



Green Algae

Green algae is an innocuous fungus that thrives in damp, shady places. Prevention may be challenging if you reside in an area with high humidity or heavy rainfall. Rapid action is required to remove algae from a fence once it has become visible. If the algae are removed, but the environment is still unfavorable, more will grow again quickly.



Mold

When moisture and organic matter are trapped within the wood, mold may quickly spread. Green, black, or brown mold spots may develop on a fence. It's harder to eradicate than green algae, but its byproducts may cause damage to wooden structures. Having plants too close to the wall might encourage rapid mold growth.



Mildew

Mold and mildew are essentially the same things. However, mildew is far less severe and seldom causes significant harm to the wood. It's not relatively as benign as green algae, but it won't do as much damage as mold. But nevertheless, it must be eliminated immediately.


Ways to Prevent Future Fence Damage



Ruining the Fence's Appearance

You can easily and quickly stain your fence. A wooden fence stain may be found at any hardware or home improvement shop. The average time to complete the task is a day. Depending on your fence, you may need to start with primer. Ask the staff at your local hardware shop for their recommendations.



Preparing to Paint the Fence

Painting is a lot like staining, but it involves one extra step. Applying a coat of paint over a stain after it has dried and set is a common finishing step. This is a perfect choice if you want a solid color rather than wood grain for your fence.



Avoid going near any trees or plants.

This makes it, so the fence dries rapidly and doesn't harbor moisture, which is what algae need to thrive and spread. If you already have any of these devices in the area around your fence, ensure you keep them in excellent condition. Maintain your landscaping by routinely cutting down overgrown bushes and trees. Keep an eye out for rocks and consider moving any within a safe distance of the fence.



Recurring Inspection, Cleaning, and Upkeep

Maintain a vigilant watch for any signs of wear and tear on your fence. Early detection of damage allows for more straightforward treatment and repair. Regular cleaning and maintenance are essential to maintain your fence in pristine condition, free from wear and green algae.


There is no reason for alarm if you see that your fence has taken on a vibrant green hue. Green algae are likely to blame and can be removed quickly. Remember that you may eliminate the green algae in a few different ways. To clean the fence, you may buy one, borrow one from a friend, or use a bleach and water solution to scrub it by hand.
