Common Mistakes to Avoid When Using Coffee Grounds

We love using coffee grounds as a natural fertilizer. But, there are some mistakes to avoid for the best results. This is key for our eco-friendly gardening efforts.

Coffee grounds are acidic, with a pH of 6.2 to 6.8. They’re great for acid-loving plants like azaleas and blueberries. But, they’re bad for plants that like neutral or alkaline soil. Too much can hurt their growth and balance.

• Avoid using coffee grounds as the only fertilizer for plants that like neutral or alkaline soil.
• Check your soil’s pH and adjust when adding coffee grounds.
• Mix coffee grounds with compost or aged manure to balance the acidity.

Don’t overdo it with coffee grounds. They’re rich in nitrogen, but too much can upset the soil’s balance. This can cause problems like poor root growth and delayed flowering.

1. Start with a small amount, like 1/2 cup per square foot of soil, and watch how plants do.
2. If plants are doing well, you can add more, but don’t go over 1 cup per square foot.
3. Keep an eye on your soil’s nitrogen levels and adjust your coffee ground use.

Knowing these common mistakes helps us use coffee grounds as fertilizer wisely. This way, we can make our gardens healthy and rich.
