What does it achieve? Do you get plants or yield double the size? Does it keep the undergardener out of mischief?
Double-digging improves the aeration of the soil, facilitates root penetration, and is especially recommended for crops such as carrots that root deeply, helping to prevent forking. It’s beneficial for new garden beds with long-term plantings, such as vegetables, perennials, cane fruits, and shrubs.
Double-digging also improves soil drainage by breaking up compaction and removing hardpan on soil.
