Grass clippings provide nitrogen, while dried leaves add carbon to the mix.

Kitchen scraps like vegetable peels and coffee grounds can also be included.

Avoid adding meat, dairy, or processed foods, as they might attract pests.

This mixture of items helps create a balanced compost that enhances soil health.

Creates A Nutrient-Rich Sublayer

The layer of compostable materials acts as a nutrient reservoir.

As these materials break down, they release essential nutrients, such as nitrogen, phosphorus, and potassium, into the soil.

This process enriches the growing medium, promoting healthy root development and vigorous plant growth.

In addition, the breakdown of materials improves soil aeration and water retention.

This results in a more suitable environment for plant roots, which require both air and moisture to thrive.

Balance Green (Nitrogen) And Brown (Carbon) Matter

Achieving a balance between green and brown materials is crucial for efficient composting.

Green materials, like grass clippings and vegetable scraps, are rich in nitrogen.

Brown materials, such as dried leaves and small branches, contain carbon.

A good ratio is roughly three parts brown to one part green material.

This balance ensures proper decomposition, while preventing unpleasant odors.

Monitoring and adjusting this ratio as needed will help maintain an effective compost layer in the garden bed.
