For decades, digging was considered an essential part of gardening. But modern insights show that less intervention often means more yield. In addition to the well-known arguments, there are other good reasons to skip digging. myHOMEBOOK presents them.
Ten Good Reasons Against Digging
Those who view their garden soil as a living ecosystem see digging differently. What was long considered a necessary maintenance measure often turns out to be an unnecessary intervention in sensitive natural processes. Beneath the surface, countless organisms work together to provide nutrients, store water, and keep plants healthy. The following points show why it’s worth trusting these processes more—and leaving the spade aside more often.
1. Soil Life Gets Out of Balance
A healthy soil is a complex network of microorganisms, fungi, bacteria, and earthworms. These creatures are specialized in certain soil layers. When the soil is turned, many of them die—along with valuable nutrient cycles.
2. Mycorrhizal Fungi Are Destroyed
Mycorrhizal fungi are particularly sensitive. They form a symbiosis with plant roots and help with nutrient absorption—especially phosphorus. Digging destroys these delicate fungal networks. As a result, plants must constantly rebuild their supply network.
3. Humus Breaks Down Faster
Humus is the heart of fertile soils. Turning the soil introduces more oxygen into deeper layers, accelerating microbial breakdown. While nutrients are released in the short term, the humus content decreases in the long term. The soil loses fertility.
4. Soil Erosion Is Promoted
Uncovered, loosened soil is more susceptible to wind and water erosion. Heavy rains can wash away the fine crumb structures. A protective mulch layer, on the other hand, stabilizes the surface and significantly reduces nutrient loss.
5. Water Retention Capacity Deteriorates
Intact soils with high humus content store water like a sponge. If the soil is regularly disturbed, this structure suffers. In dry summers, dug-up beds dry out faster—increasing the need for watering.
6. Weed Seeds Are Activated
Seeds often lie dormant in the soil, remaining viable for years. Turning the soil brings them to light, and they begin to grow. Those who avoid digging keep this “seed bank” largely dormant.
7. Nutrients Are Washed Out
After digging, nutrients are more exposed and can be washed into the groundwater more easily during heavy rain. This is not only bad for the plants but also for the environment.
8. Soil Compaction in Deeper Layers
Paradoxically, frequent digging can lead to a so-called “spade sole”—a compacted layer below the working depth. Water and roots then have a harder time penetrating.
9. More CO2 Emissions
The soil stores large amounts of carbon and plays an important role in the climate system. Carbon is bound in the soil through plant residues and roots and held over long periods. Intensive cultivation, such as frequent plowing, introduces oxygen into deeper layers and accelerates the breakdown of organic matter. Stored carbon is released as CO2. Those who opt for gentle methods contribute to climate protection in a small way.
10. More Work Than Necessary
Last but not least, digging is physically demanding. The “No-Dig” principle instead relies on mulching and regular compost applications. Earthworms naturally take care of loosening the soil. The “No-Dig” approach, attributed to English gardener and author Charles Dowding, emphasizes the benefits of avoiding digging.

Mulching and Avoiding Digging
A five to ten centimeter thick layer of compost, leaves, or grass clippings protects the soil, promotes soil life, and ensures stable structures in the long term. Especially in times of hot, dry summers, this method is significantly more sustainable and efficient.
When Digging Can Be Useful
After construction work or in extremely compacted soils, a one-time deep loosening can help. However, certain tools should be avoided: “Motor tillers and motor hoes should stay in the shed, as these devices can shred soil organisms like earthworms and woodlice—resulting in a lack of these organisms for the formation of valuable humus,” recommends Sandra von Rekowski from the Federal Association of Allotment Gardeners in Germany in a previous interview with myHOMEBOOK. In the long term, it is worthwhile to understand the soil as a living system—and to subject it to as little “disruption” as possible. Those who consistently opt for gentle soil cultivation will be rewarded with healthy plants, less weed pressure, and noticeably more fertile garden soil.
“Laziness” Protects the Soil
“Even on a small scale, avoiding digging can have advantages. For example, I never dig up my small raised bed. In the fall, I remove plant residues from the summer planting and layer semi-decomposed compost, leaves, and the last grass clippings on the raised bed. This mulch layer protects the soil in the raised bed during the winter and slowly decomposes. By spring, it has become fertile humus, which I supplement with some potting soil or mature compost as needed. This not only saves me a lot of time and work but also allows me to sustainably dispose of large amounts of garden waste.”
