17 Plants That Thrive with Coffee Grounds – Boost Growth Naturally
Did you know your used coffee grounds can work wonders in the garden? Rich in essential nutrients like nitrogen, phosphorus, and potassium, coffee grounds also help improve soil structure and increase acidity—ideal for many acid-loving plants. When used correctly, they can transform your garden’s growth and vitality.
How to Use Coffee Grounds Safely:
• Use in moderation. Too much can make your soil overly acidic.
• Sprinkle lightly around the base of plants or brew into compost tea for natural fertilizing.
• Avoid thick layers, which can block water and air from reaching the soil.
How to Test Soil Acidity:
Use a soil pH test kit (available online or at garden centers). Most plants prefer slightly acidic to neutral soil, and this test helps determine if your soil will benefit from the added acidity of coffee grounds.
