Composting Coffee Grounds:

Composting your coffee grounds is probably the best way to use them in the garden. When we discussed composting we spoke about carbon and nitrogen ratio

Coffee grounds add a lot of nitrogen to your compost pile. So whenever you use coffee grounds don’t forget to add grass clippings, dry leaves, newspapers etc that have a lot of carbon in them. For example add four parts of shredded leaves to one part of coffee grounds to make a proper C:N ratio. 

Sprinkling Coffee Grounds:

If you do not want to do composting, you can also sprinkle coffee grounds directly on the soil. Simply, mix one part of the coffee grounds to five parts of soil for your plants.

Benefits of Using Eggshells As A Fertilizer:

Calcium is a very important and crucial nutrient for plants. Eggshells are full of calcium. So, it gives an extra boost of calcium to plants.

Eggshells also give a natural protection to plants from slugs as well.

Alternatively, you can crush the eggshells by hand and add them on top of the soil. This will act as pest repellent. It will protect your plants from snails and slugs. 

Eggs are known carriers of salmonella. So, always rinse the eggs well and let them dry on a sunny windowsill before using. Dryness usually kills any salmonella present on the eggs.
