Green algae can make garden fences look unsightly and even weaken the wood over time, but a simple kitchen staple costing as little as 57p can solve the problem. White vinegar, available at supermarkets like Asda, is an effective natural solution for removing algae from wooden fences.
Gardening experts at B&Q warn that green algae is not just an eyesore; it can compromise the timber, potentially leading to costly repairs. Fences in shaded areas are particularly susceptible, as are those near plants being watered, which provides moisture for algae growth.
To clean a fence, mix one part white vinegar with one or two parts water, using a stronger solution for heavily affected areas. Apply the mixture with a sponge or spray bottle, starting at the top and working downwards. Allow it to sit for 10 to 15 minutes without drying, then scrub with a brush or sponge using circular motions.
After scrubbing, rinse the fence thoroughly with a hose to remove all traces of vinegar and prevent streaking. For composite or metal fences, check that the solution will not damage the finish. Always protect nearby plants and wear gloves and goggles for safety.
