Garden fences are an ideal spot for algae to grow as the wood absorbs moisture from rain and dew, creating the perfect breeding ground for algae to grow and thrive.
Algae love damp and shady environments, so if your garden fence is located in an area that gets limited sunlight, you’re more likely to see algae growing.
Luckily, fans of cleaning sensation Mrs Hinch have shared their go-to method for removing the unsightly green substance from garden fences.
Catherine Ingledew posted on the Facebook group, ‘Mrs Hinch Cleaning Tips’, “Any handy tips for removing green mould from garden fences? Thanks for your advice in advance.”
The green substance on the garden fence was likely algae, which appears as a green film on fences, paths, and decking.
The post was inundated with more than 20 comments from fellow cleaning and gardening enthusiasts. The most suggested method was to use a product called Wet & Forget.
Mwahreen Davidson said: “Wet and Forget – spray it on fences, paths, etc.”
Ally Allen agreed and wrote: “Use Wet & Forget. Spray it on and leave it to work. Cover grass/plants when spraying. It can be used on stone ornaments/driveways/patios as well. Continues to work for approximately six months.”
Lorraine Julie Gallagher commented: “Wet & Forget. Put on ours five years ago. Good as new.”
Sandra Allan agreed and replied to Lorraine’s comment, claiming it was the “best” product she had ever used for the task.
Wet & Forget Outdoor Mould, Lichen, and Algae Remover claims to remove “contaminants such as mould, lichen, and algae without using harsh methods.”
It can be bought from The Range for £23.99, B&Q for 18.89 and Amazon for £27.30.
The item has received a 4.4 out of five rating on Amazon, with 64% of the ratings being five-star.
One reviewer called Mrs P, who gave the product five stars, wrote: “So easy to use and good results. Used a new watering can to use just with this product so not affecting plants. Measured product added water and watered area and let it works its magic.”
Another wrote: “This product is the best on the market and worth the cost. My fences have looked great for years with a treatment every five to seven years or so.
“Plus, unlike high-pressure cleaning, it doesn’t remove the pine wood treatment, meaning it is clean but not exposed to termite damage.”
However, some reviewers claimed the product wasn’t as effective as they hoped.
A. Smith wrote: “Only works neat and that was on minimal moss! Never worked diluted. Moss has grown back already. I used this in the summer, dry hot day. Waste of money.”
Michael Eves said, “This is rubbish. I’ve seen no difference at all, and it did exactly what it says as well.”
Other suggestions from Mrs Hinch fans included using a jet washer or white vinegar to remove green algae from garden fences.
Marion Houlden said: “White vinegar does the trick.”
Catherine Thomson commented: “Spray with white vinegar. It takes a few days, but it will disappear.”
Helen Dawes wrote: “So long as the fence isn’t rotten, jet washing works really well,l but you will need to repaint afterwards.”
