6. Beneficial Fungi and Microorganisms
Coffee grounds attract beneficial microorganisms and fungi that can help improve nutrient absorption and enhance soil health. These microbes contribute not only to overall soil structure but also your plants’ ability to take up nutrients effectively.
How to Enhance Microbial Activity:
Apply coffee grounds in moderation; over-applying can lead to compaction and may create an overly acidic environment. Mixing grounds with other organic materials in your garden will maintain balance.
7. Weed Suppression
Layering coffee grounds on top of your garden beds can act as a mulch that suppresses weed growth. Coffee grounds block sunlight from reaching weed seeds, helping to keep your garden tidy and productive.
Application Tips:
Spread coffee grounds in a thin layer around plants to manage weed growth while still allowing moisture to reach the soil.
8. Attracting Beneficial Insects
The use of coffee grounds can attract beneficial insects, such as ladybugs and lacewings, which prey on pests that pose a threat to your garden.
How to Attract Beneficial Insects:
Incorporate coffee grounds into your compost or scatter a thin layer around plants to create a welcoming environment for these helpful critters.
The Dos and Don’ts of Using Coffee Grounds
While coffee grounds are a fantastic resource, moderation is key. Here are some essential dos and don’ts to keep in mind.
