Summary Not Available – First paragraph follows:
The depth at which asparagus crowns are placed in the soil or are direct-seeded varies in California between production areas and between growers in a single area. The influence of different seeding depths on asparagus production has not been clear. Some studies show that ridging increases yields. These studies do not specify the depth of soil cover over the plants, however.
