Why Coffee Grounds and Eggshells?
Before we get into the nitty-gritty, you might be wondering, “Why coffee grounds and eggshells?” Well, these kitchen scraps offer fantastic benefits for your plants:
- Coffee Grounds: They’re a great source of organic matter and provide a slow-release nitrogen boost to your soil. Plus, they can deter certain pests.
- Eggshells: Crushed eggshells are rich in calcium, which can help prevent blossom end rot in tomatoes and other calcium-hungry plants.
Now, let’s explore the plants that truly appreciate these natural goodies.
Plants That Love Coffee Grounds
1. Tomatoes (Solanum lycopersicum)
Why they love it: Tomatoes are heavy feeders and can benefit from the nitrogen boost coffee grounds provide.
How to use coffee grounds: Mix used coffee grounds into the soil or sprinkle them around the base of your tomato plants.
2. Roses (Rosa spp.)
Why they love it: Roses thrive on the organic matter in coffee grounds, and the grounds can help deter pests like snails and slugs.
How to use coffee grounds: Spread coffee grounds around the base of your rose bushes to improve soil quality and protect against pests.
3. Blueberries (Vaccinium spp.)
Why they love it: Blueberries prefer acidic soil, and coffee grounds can help lower the pH, making it more acidic.
How to use coffee grounds: Incorporate coffee grounds into the soil around your blueberry bushes to create a more favorable acidic environment.
4. Azaleas (Rhododendron spp.)
Why they love it: Azaleas, like blueberries, thrive in acidic soil conditions.
How to use coffee grounds: Mix coffee grounds into the soil around your azaleas to enhance their growth.
Plants That Thrive on Eggshells
1. Tomatoes (Solanum lycopersicum)
Why they love it: Tomatoes, once again, benefit from the calcium boost that crushed eggshells provide.
How to use eggshells: Crushed eggshells can be sprinkled directly into the planting hole when you’re transplanting tomatoes or applied as a top dressing around established plants.
2. Peppers (Capsicum spp.)
Why they love it: Just like tomatoes, peppers appreciate the calcium for strong cell walls and disease prevention.
How to use eggshells: Sprinkle crushed eggshells around the base of your pepper plants to provide a steady calcium supply.
3. Eggplants (Solanum melongena)
Why they love it: Eggplants belong to the same Solanaceae family as tomatoes and peppers, so they share the love for calcium-rich eggshells.
How to use eggshells: Incorporate crushed eggshells into the soil when planting eggplants or sprinkle them around established plants.
Plants That Benefit from Both
1. Hydrangeas (Hydrangea spp.)
Why they love it: Hydrangeas appreciate the acidic pH from coffee grounds and the calcium from eggshells.
How to use both: Mix coffee grounds and crushed eggshells into the soil around your hydrangeas to encourage vibrant blooms.
2. Roses (Rosa spp.)
Why they love it: Roses are repeat offenders here because they enjoy the nitrogen from coffee grounds and the calcium from eggshells.
How to use both: Combine coffee grounds and crushed eggshells, then apply the mixture around your rose bushes for a double dose of goodness.
