Planting roots speeds up harvest by at least 1 to 2 years. Plant roots shortly after receiving them in a well prepared, deeply dug, fertilized bed with plenty of organic matter. Prefer light, loose soil. Set roots in trenched rows 12 inches apart, rows 3 to 5 feet apart. Trench should be 6 inches deep. Cover roots with 2 inches of soil. Fill in the trench as asparagus grows. Keep moist. Fertilize again the next spring. Begin harvest in 2 to 3 years. Sorry, no shipments to AZ, HI, or CA.
