Can Beer or Pop Fertilize Your Lawn?

Debunking This Generations-Old Lawn Care Myth

At Weed Man, we want you to kick back and relax on your lush, green lawn, with a cold beer or pop in hand (not in the dirt)! As strange as it may seem, there are some who believe that these cold beverages can actually be used as a replacement for fertilizer in your lawn or garden. Let’s debunk this generations-old lawn care myth – the truth is if you’re in the habit of sprinkling beer over your lawn, you’re probably doing more harm than good. 

Where Did This Myth Come From?

At the surface level, it might sound plausible to harness the ingredients in beer and pop for the good of your lawn and garden. Beer is made of grain, hops, yeast, and water, and it does contain some of the major nutrients that your lawn craves: phosphorus, calcium, potassium, magnesium, sulfur, and nitrogen.


Unfortunately, there’s not much evidence that beer is an ideal source of any of these nutrients. The alcohol content in beer can actually be damaging to the microbes in your soil. The simple carbohydrates in beer are the wrong kind of carbohydrates for stimulating plant growth, and the carbon dioxide in beer is unnecessary, as your lawn can absorb all the carbon dioxide it needs from the air. All that sugar in beer can also result in insect infestations and the spread of lawn diseases; it can even inhibit the grass plant from effectively absorbing water


At best, watering your lawn with diluted beer is pretty ineffective. At worst, it’s actively harmful. The same goes for sodas and soft drinks, which also have high sugar content.

What Really Works – Weed Man’s Custom Fertilizer Blend

No surprises here. The science behind feeding your lawn is a little more complicated than just diluting beer and soft drinks. That’s why Weed Man uses a proprietary high-percentage, slow-release granular fertilizer to deliver the most nutritious ingredients to your lawn.



Our premium, golf course-quality mixture gives your lawn a boost from the get-go, and then continually feeds it over the following weeks to months. Our fertilizer is blended using the latest slow-release technology, so it releases a small, steady amount of nutrients over time – only when your lawn needs it. This allows the grass plants to feed for an extended period, rather than feasting all at once, which is more environmentally friendly.

Here are some benefits of Weed Man’s custom fertilizer blend:

  • Consistent And Prolonged Nutrient Supply: Weed Man’s custom fertilizer blend combines essential nutrients, including Nitrogen, Potassium, and other macronutrients like sulfur and magnesium. Nitrogen aids in plant growth and helps keep grass looking green and healthy, while Potassium increases weather hardiness and resistance to disease and drought. Our slow-release granular fertilizer will provide a steady supply of nutrients to plants over an extended period of time, which can help to promote healthy growth and improve overall plant health.

  • Reduced Leaching: Slow-release fertilizers reduce the risk of nutrients being lost due to leaching, which can occur when water washes the nutrients out of the soil.

  • Improved Efficiency: Slow-release fertilizers are more efficient than traditional, water-soluble fertilizers because they can be applied less frequently, reducing the amount of fertilizer needed overall.

  • Reduced Risk Of Over-Fertilization: Over-fertilization can lead to a number of problems, including plant stress, leaf burn, and root damage. Slow-release fertilizers help to reduce the risk of over-fertilization by providing a consistent and controlled supply of nutrients.


When it comes to fertilizer, opt for a top-of-the-line product that was designed with your lawn in mind (and save the beverages for yourself).
