As the clocks go back and dark November evenings set in, many gardeners are tempted to ignore their outdoor space until spring. But horticulture experts advise against both abandoning the garden and digging it up during winter.
Turning over cold, wet soil can destroy its natural structure, causing severe compaction and clumping that suffocates roots, ruins drainage, and kills vital soil life.
Cardboard no-dig method
Instead of using a spade, gardening content creator Amy May has shared a "no-dig" sheet mulching method on YouTube that uses leftover delivery boxes. The technique is free and eco-friendly, suppressing weeds, locking in moisture, and creating fertile growing areas for spring.
To start, clear the patch by cutting back tall weeds and grass, and remove large rocks and debris. Then lay plain brown cardboard directly over the soil, ensuring any plastic tape, staples, or glossy labels are stripped off first.
How to apply the layers
The cardboard edges should overlap by about four inches to block out sunlight, which starves the weeds underneath. After laying it down, soak the cardboard with a watering can to kickstart the breakdown process.
Finally, pile on organic matter such as compost, fallen leaves, or grass clippings, and top it with a thick layer of mulch to weigh it down.
Over the winter, the cardboard rots down, providing rich feed for the earth and leaving weed-free soil by spring.
