Effective Ways to Eliminate Moss on Your Patio

Moss can ruin the aesthetic of your outdoor seating area, but removing it from your patio is straightforward.

Fortunately, you can choose from various natural and chemical techniques that yield impressive results.

Here, gardening professionals share their best tips for tackling moss on patios, prepping your space for spring and summer gatherings.

Eliminating Moss on a Patio

When addressing moss on patio surfaces like pavers or bricks, consider whether a chemical or natural approach suits your needs.

Chemical treatments can provide quick results, but they may harm your yard and pose risks to pets and children. Natural methods are slower but generally safer. Many natural solutions can also help clear moss from lawns.

Our experts present their top strategies for a green patio.

1. Use Vinegar to Kill Moss Naturally

A sunny paved patio with a white panelled house, circular table with wicker chairs and a large white, open umbrella — Vinegar effectively targets newly formed moss patches.

Ryan Harden from The Harden Garden recommends vinegar as a primary method for moss removal.

He explains, 'Vinegar's acetic acid alters the pH balance of moss without harsh chemicals.'

In a clean spray bottle [three-pack at Walmart], mix equal parts water and vinegar, then spray generously on mossy areas, focusing on damp spots. After 24-48 hours, scrub with a stiff-bristled brush from Home Depot, then rinse thoroughly.

'For optimal results, try this on a dry, sunny day for better absorption and drying.'

2. Pressure Washing

pressure washing a patio — Pressure washing is an eco-friendly method that uses no chemicals.

Regular power washing is a habit of those with pristine patios. It effectively dislodges moss without harsh substances.

Ryan advises, 'High-pressure water streams eliminate spores, preventing regrowth.'

For effective pressure washing, set your washer to low to protect the paver surfaces. Work on small sections at a consistent angle.

Using this method on sunny days helps the area dry thoroughly, reducing the risk of moss re-infestation.

If you lack a pressure washer, consider renting one from Home Depot or your local rental shop.

3. Use a Commercial Spray

For fast-acting, long-lasting results with a gentle chemical solution, Chris Turner from Elevate by Design suggests Wet & Forget Moss Remover, available on Amazon.

He notes, 'Just spray and let rain do the rest over time.'

This spray reduces scrubbing, conserves water, and is bleach-free, making it more environmentally friendly. However, avoid using it near aquatic life.

4. Apply Lawn Sand

Lawn Sand from Amazon consists of iron sulfate, ammonia sulfate, and dry sand, effectively killing moss without harming adjacent grass.

Sprinkle it onto the affected area; it will eliminate both moss and broadleaf weeds. Once they turn black, simply sweep or hose off the sand.

5. Use Diluted Bleach

While harsh chemicals aren't always necessary, Rafi Friedman from Coastal Luxury Outdoors suggests using a mild bleach solution for stubborn moss. Use it sparingly, as too much can harm your patio or surrounding lawn.

To minimize damage, apply bleach with a spray bottle directly to the moss.

Handle with care

Bleach is an aggressive cleaner effective against living organisms like moss. Always use in well-ventilated areas and wear gloves to protect your skin.

Avoid spills

When transferring bleach into a spray bottle, a funnel can help prevent spills that might damage surfaces or skin.

A glass spray bottle is preferable for bleach to prevent plastic warping or leaks.

Preventing Moss on Your Patio

Preventing moss growth focuses on minimizing conditions that favor it, according to Chris Turner. 'Moss thrives in shaded, damp, and poorly drained areas where moisture lingers and sunlight is sparse.'

To prevent moss on your patio:

Enhance drainage to divert water and eliminate damp spots.
Increase sun exposure by trimming overhanging plants and clearing debris.
Seal your patio with a quality protectant like BEHR Premium Wet Look Sealer from Home Depot. This can help limit moisture penetration and deter moss and algae.
Address moss promptly to prevent its spread.
Regularly clean your patio to remove debris.

FAQs

Can washing powder remove moss?

Biological washing powder or dish soap can kill moss when sprinkled generously. Consider nearby plants and how to clean up afterward.

Using a broom or pressure washer is often simpler, allowing for easy composting of the dead moss.

Does baking soda eliminate moss from patios?

Baking soda can kill small patches of fresh moss when sprinkled on wet areas, but it's slow and hard to wash off. Better options include a stiff broom, pressure washer, or vinegar.

Many natural methods for removing moss on patios can also be used to clean outdoor furniture. Always check the manufacturer's guidelines and test in a small, hidden area first to avoid damage.
