The Basics of No-Dig Gardening
No-Dig gardening, also known as ‘lasagna gardening’ or ‘layer gardening’, is a method that prioritises soil health by minimising disturbance. As the name suggests, gardeners practicing this technique refrain from turning the soil and instead build up organic matter on the surface. This approach helps to preserve the soil’s structure, protect the ecosystem beneath the surface, and retain moisture.
The Benefits of No-Dig Gardening
Soil Health and Fertility
By leaving the soil undisturbed, the No-Dig method helps maintain the soil’s structure and biodiversity. This allows beneficial organisms like earthworms and microbes to thrive. These organisms decompose the organic matter on the surface, enriching the soil with nutrients, and improving its fertility over time.
Reduced Weed Growth
Regular digging or tilling can bring dormant weed seeds to the surface, where they germinate. No-Dig gardening reduces weed problems by leaving these seeds buried and undisturbed.
No-Dig gardening can also play a role in mitigating climate change. Soil is one of the most significant carbon sinks on Earth, and tilling or digging can release this stored carbon back into the atmosphere. The No-Dig method helps keep carbon locked in the soil.
By improving the soil structure and organic matter content, No-Dig gardening increases the soil’s water-holding capacity. This leads to less frequent watering, saving a valuable resource.
How to Start a No-Dig Garden
Starting a No-Dig garden is straightforward. Begin by laying cardboard or newspaper directly onto the ground to suppress weeds, followed by layers of compost, well-rotted manure, or other organic materials. The garden beds can be topped off with a final layer of compost or mulch, ready for planting.
In conclusion, the No-Dig gardening method is much more than just a trend; it’s a sustainable practice that can help us build healthier gardens while mitigating some of the impacts of climate change. As Charles Dowding, one of the pioneers of the No-Dig method, often says, “Let the soil organisms do the digging.”
