panels made out of wood are quickly susceptible to algae buildup, in turn giving an unsightly look to your garden.

Green algae typically form slimy layers on surfaces, which can lead to slippery and nasty-looking fencing.

The reason for this growth is the damp climate in many parts of the UK that creates ideal conditions for these organisms to thrive on wooden surfaces.

Without proper removal, algae can cause the wood to rot, weakening the structure of your fence. 

Taking to the Hints and Tips Facebook page, Charlotte Burrows asked: “Tips please for removing algae off of a fence. I’ve tried vinegar and bleach, but it won’t budge.”

Instead of using a home remedy like and bleach or purchasing a pressure washer, gardening fans have suggested a product that works fast and prevents these stains from appearing for years.

Gardening enthusiasts were in agreement that Wet and Forget, which retails at Wickes for £18 and on Amazon for £22.99, works the best to clear fences of algae.

Wendy Ashton wrote: “Wet and Forget, it’s brilliant. I use it once a year on my fence, bricks and patio. Spray and leave it to do its thing.”

Garry Parnell wrote: “As Wendy Ashton said, Wet and Forget. Just mix five parts water and one part Wet and Forget in a spray bottle do it on an overcast day.”

Joseph Mcilvan instructed: “Brush on Wet and Forget. One application lasts three years. No scrubbing. It’s genius.”

Shelley Jessop said: “Wet and Forget will do it and keep it from growing back.”

Wet and Forget mould, lichen and algae remover is an outdoor cleaning solution that is made up of a formula that “has an unlimited shelf life and is completely free from aggressive chemicals such as bleach and ammonia that can damage surfaces”.

Alternatively, a few gardeners suggested using another similar product - Patio Magic. Anne Baylis wrote: “I've used Patio Magic. Spray, leave and watch the green algae disappear.”

Gail Wilkinson replied: “I used that this year. It’s brilliant. Not cheap, but well worth it. Great for decking and the patio too.”

Jodie Owen wrote: “I used Patio Magic and just left it on overnight. Doesn’t damage plants and worked amazingly.”

Patio magic currently retails for £10.63 down from £13.99 on Amazon and for £12.75 at B&Q.
