7 Ways to Use Beer in the Garden 2023

Beer is a popular beverage that is enjoyed by many people worldwide. However, did you know that beer can also be used in gardening? That’s right, this beloved beverage can be utilised to help your plants grow healthier and stronger. In this article, we will explore the various ways in which you can use beer in gardening. Pro tip: you may want to let the beer/wine sit for a couple hours to allow the all the alcohol evaporate before following the steps below (alcohol can be harmful to plants).

1. Beer as a Fertiliser

Beer contains many essential nutrients that plants need to grow, including nitrogen, phosphorus, and potassium. These nutrients can help to promote strong root growth and encourage the development of healthy leaves, stems, and flowers. To use beer as a fertiliser simply pour it around the base of your plants, making sure that it reaches the roots. This can be done once a week, but be sure to water the plants afterwards to dilute the beer and prevent any damage to the roots.

2. Beer as a Pest Repellent

Beer can also be used as a natural pest repellent. Slugs and snails, in particular, are attracted to the yeast in beer, and will crawl into the container to drink it. Unfortunately, they will become trapped in the beer and eventually drown, effectively removing them from your garden. Simply place a shallow dish filled with beer near the plants you want to protect and replace the beer every few days. In addition to slugs, beer can also be used to repel other pests such as ants, snails, and earwigs. To use beer as a pest control, fill a spray bottle with beer and spray it directly onto the pests. The alcohol in the beer will kill the pests on contact.

3. Beer as a Compost Accelerator

Beer can also be used to speed up the decomposition of organic material in your compost pile. The yeast in beer will help to break down the material, creating a richer and more nutrient-rich compost for your garden. Simply add a few cans of beer to your compost pile along with your other organic materials and let the composting process begin.

4. Beer for Irrigation

Beer can also be used to water your plants. The yeast in the beer will help to create a natural compost tea, which will provide your plants with the essential nutrients they need to thrive. Simply dilute the beer with water and use it to water your plants once a week. This can also help to improve the health of the soil in your garden, as the yeast will release beneficial microorganisms into the soil.

5. Beer for Seed Germination

Finally, beer can also be used to improve the germination of seeds in your garden. The yeast in the beer will provide the seeds with the nutrients they need to grow and thrive. Simply soak the seeds in a shallow dish filled with beer overnight, then plant the seeds in your garden the next day. This can help to ensure that your seeds will grow into healthy, thriving plants.

6. Attracting Beneficial Insects

Beer can also be used to attract beneficial insects to your garden. For example, beer traps can be used to attract and trap beneficial insects such as ladybugs, lacewings, and hoverflies. To make a beer trap, simply bury a shallow dish filled with beer in your garden. The insects will be attracted to the beer and will crawl into the dish.

Finally, beer can also be used to promote plant growth. The sugars and nutrients in the beer can help to stimulate plant growth and improve overall plant health. To use beer to promote plant growth, simply dilute a can of beer with a gallon of water and use it to water your plants.


In conclusion, beer can be a great tool for any gardener. It can be used for slug control, fertilizer, pest control, soil conditioning, composting, attracting beneficial insects, and promoting plant growth. The next time you crack open a cold one, consider using the leftover beer in your garden. Not only will it help your plants thrive, but it will also make you feel good about repurposing something that would otherwise go to waste. So, cheers to a healthy and thriving garden!
