What Is the Green Stuff on My New Picket Fence? Exploring Common Causes and Solutions

It’s a common occurrence for homeowners to notice green growth on their new picket fences. This mysterious "green stuff" can be quite alarming, as it not only affects the aesthetic appeal of the fence but also raises concerns about the health and durability of the wood. Two common culprits behind this green growth are mildew and green algae. Mildew is a type of fungus that thrives in damp environments, making it likely to appear on fences that don't dry out often. As it spreads, it can gradually eat away at the wood and cause damage. Green algae, on the other hand, is a slippery green fungus that can also grow on wood that doesn't air out frequently. Both of these issues can be problematic, but fortunately, there are solutions to combat and prevent their growth.

Algae is a common problem that occurs on outdoor surfaces, particularly wooden fences, due to it’s constant exposure to moisture and sunlight. The green tinge on your picket fence is actually a manifestation of algae buildup, which can be both unsightly and detrimental to the fences longevity.

Trimming nearby vegetation can also help to increase sunlight exposure, reducing the dampness that favors algae.

Regular maintenance, proper drainage, and protective coatings are key to preventing and combating algae growth.
