Ensuring your soil remains moist is crucial for supporting the activity of earthworms throughout your garden. These beneficial creatures rely on moisture to survive and move through the soil. To retain moisture, cover your garden beds and pots with materials that allow water penetration while still allowing the soil to breathe.
Personally, I find grass clippings and leaves to be excellent choices due to their accessibility and free availability. However, you can use a variety of materials such as hay, straw, lucerne, coconut fibre, mulched palm fronds, or hoop pine mulch. Avoid using materials like fake bark or black plastic, as they inhibit water and air circulation in the soil.
Shredded bamboo is an exceptional option as it breaks down slowly, maintains its structure, and allows water to pass through. Although it comes with a cost, its durability and functionality make it worth considering.
If you opt for grass clippings and leaves, which provide an ideal carbon-to-nitrogen ratio, consider placing irrigation tape or pipes beneath them to prevent matting. This method ensures thorough watering, encourages earthworm activity, and gradually transforms the organic matter into nutrient-rich soil.
By regularly replenishing your grass clippings and leaves, you can suppress weed growth effectively. Additionally, ensure not to layer them too thickly around the base of trees or plants to avoid harming them.
One of the greatest benefits of using grass clippings and leaves is their rapid breakdown process, which minimizes the presence of compost flies and eliminates the need for frequent turning, unlike traditional compost piles. This effortless decomposition process ultimately yields nutrient-rich soil without the labour-intensive tasks associated with composting.
