Urgent warning issued to anyone pouring beer on their lawns

You might think you’re doing your a favour by tipping leftover beer onto it, but experts are urging homeowners to stop immediately. While it may seem harmless, the truth is that pouring alcohol on your can be having the opposite effect.

The idea comes from a long-standing myth that the ingredients in beer, like hops, grain, and yeast, can help nourish . At a glance, it might sound plausible, especially when you consider that beer contains trace nutrients like nitrogen and potassium.

But the problem lies in the other ingredients that come along for the ride. The alcohol content, for starters, is known to harm the healthy microbes that live in your soil and keep your lawn thriving.

These microbes play an essential role in breaking down nutrients, supporting root growth, and building resilience against disease. Damaging that ecosystem throws off the balance, leaving your grass vulnerable and stressed.

Then there’s the sugar. Beer and soft drinks contain high levels of sugar, which can attract pests like ants, wasps, and other insects you'd rather not have burrowing into your garden.

Even worse, sugar can lead to fungal infections in the grass and soil. Over time, this can create unsightly patches and unpleasant smells, hardly the lush lawn you were aiming for.

And while some argue that the carbon dioxide in fizzy drinks might be useful, the science doesn’t back it up. Your grass gets all the carbon dioxide it needs from the air naturally; there’s no need to pour it from a bottle.

Sodas also contain acids and artificial colours that are of no benefit to plants. In fact, many of these additives can interrupt the natural pH of your soil, making it harder for your grass to absorb water.

At best, using beer or fizzy drinks as a fertiliser is ineffective. At worst, it’s a surefire way to end up with a patchy, bug-infested, thirsty lawn.

Proper fertilising isn’t about quick fixes, it’s about consistency, timing, and the right ingredients. A balanced, slow-release fertiliser is designed to give your grass what it needs, when it needs it.

These products deliver nutrients gradually, encouraging strong roots and vibrant colour without the shock of an all-at-once feeding. They also reduce waste, runoff, and the risk of overdoing it.

So next time you’re tempted to pour a pint out for your garden, take a step back. Pop it in the fridge instead and let your lawn drink what it really needs, water and the proper nutrients.
