UK households are being urged to use two supermarket items to remove green algae from garden sheds, decking and outdoor buildings for just £1.
During the , wintry conditions can wreak havoc on outdoor with creating damp conditions for algae to thrive.
The unsightly substance needs moisture, nutrients and light to grow, so if your fence, decking or shed are consistently exposed to , it’s likely you’ll notice a layer of green algae forming over time.
While algae is not only an eyesore, it can cause damage to the structural integrity of wooden structures so it needs to be properly managed.
Shed and log cabin expert Sam Jenkinson, from garden building retailer , explains: “Algae thrives in damp, shaded areas, and poor drainage creates the ideal breeding ground for green algae. Without proper water management, moisture builds up and the algae will flourish.
“This is an issue for wooden structures, such as sheds and , as when algae grows on wood, it retains moisture which can then seep into the wood, which over time can lead to the deterioration of a garden building’s structural integrity.
“To prevent green algae from growing on your garden buildings, the trick is to reduce moisture build-up around the structure by creating better drainage and airflow.”
Mr Jenkinson says prevention can be achieved in four simple steps, by ensuring proper drainage around any wooden structures, clearing your gutters regularly to prevent water overflowing, maximising sunlight and airflow by trimming back bushes and branches, and weatherproofing structures with mould-resistant or weatherproof paint.
If you already have green algae growing on structures in your garden then it is possible to tackle the problem with a simple homemade solution of bleach and white vinegar.
You can pick up a bottle of bleach for as little as 65p at Aldi, while a bottle of white vinegar costs just 35p, meaning you can blitz your garden of the green substance for a mere £1.
Mr Jenkinson adds: “You can use items already in your kitchen cupboards, such as bleach and vinegar, to create an effective cleaning solution. Simply mix one part bleach with 10 parts water – or use a vinegar solution of equal parts vinegar and water for a gentler, eco-friendly alternative.
“Soak the algae-affected areas with your cleaning solution using a spray bottle or cloth and allow it to sit for 10-15 minutes. Use a stiff-bristled brush to scrub away the algae. For stubborn patches, reapply the solution and scrub again. After scrubbing, rinse the area with a garden hose to remove all the algae and cleaning solution.”
