Grow asparagus in the South by choosing a planting site with access to full sun, using well-drained soil and mulching the plants. For southern locations, start planting the asparagus crowns as early as early January to late March.Continue Reading
First, choose a planting site that has access to full sun and well-drained soil. Because asparagus plants can create shade, avoid planting sun-loving plants close by them. Work compost or manure into the soil to improve drainage and add nutrients. Keep the soil pH between 5.8 and 6.5, and add lime or sulfur to raise or lower the acidity as required. Amend the pH several months in advance of planting.
Next, dig an 8-inch deep, 18-inch wide trench for the plants. Place young asparagus crowns in the trench with at least 15 inches between each plant, and add fertilizer to the soil as you fill in the trench. Feed the asparagus plants with nitrogen fertilizer twice a year, once in the early spring and again after the harvest.
Water the plants regularly during the growing season, and add a 2- to 3-inch layer of mulch to keep the roots moist. Only harvest asparagus once it reaches its third year. Collect the stalks in the spring.Learn more about Agriculture
