Gardeners are being encouraged to drop a simple penny into their birdbath this April to keep water cleaner and more inviting for wildlife. Experts say the low-cost trick works thanks to the copper found in coins, which naturally helps slow the growth of algae in standing water.
This can prevent the slimy green build-up that often forms in birdbaths as temperatures begin to rise in spring. Algae not only looks unsightly but can also make water less appealing—and potentially unsafe—for birds. Sam Stevens, garden design expert at Pergolux UK, said: “Spring is on its way, and a lot of people will be looking at their gardens and getting them ready for brighter and longer days ahead.
“Cleaning the garden doesn’t have to be an expensive job at all. We all love a cheap and cheerful hack and the good news is that there are plenty of items you’ll already have in your home that can be used in the garden.
“Whether you need to buff away stains, achieve a streak-free finish on glass or get rid of rust, there will be something in your house for everything.”
By placing a penny in the basin, gardeners can help create conditions that discourage the growth of these microorganisms, keeping water fresher for longer.
The hack is simple to try. Gardeners just need to place one or two clean coins at the bottom of the birdbath.
Some experts recommend giving the pennies a quick clean beforehand to remove dirt or residue before adding them to the water.
While the trick can help reduce algae, it is not a replacement for regular maintenance.
Lucy Taylor, bird expert for Vine House Farm, added: “Clean bird baths daily and allow them to air dry before refilling.
“The drying process helps ensure that the Trichomonosis parasite does not survive.”
Birdbaths should still be topped up with fresh water daily and scrubbed regularly to keep them safe for visiting wildlife.
With April marking the start of warmer weather and increased wildlife activity, experts say now is the ideal time to prepare bird-friendly gardens.
A single penny could be a simple way to keep birdbaths cleaner—and encourage more birds to visit throughout the season.
