Question: When and how do I plant asparagus?
Answer: Buy dormant two-year-old roots in January. Choose one of the improved varieties from a local nursery or vegetable specialist. Set them into 10-inch-deep trenches, spacing the roots 15 inches apart in the trenches. The trenches, if you have more than one row, should be dug 5 to 6 feet apart. Asparagus plants grow quite large as they mature. Cover the roots with 3 to 4 inches of the soil mix, then soak it heavily. As the crowns start to grow, you can gradually add more soil until the trenches are filled.
