It’s recommended that you start asparagus seeds indoors or in a greenhouse in mid-February to May under bright lighting. Soil temperatures for seed germination should be between 70-85 degrees F. (21-29 C.). Soak the seeds for a couple of hours, then plant each seed ½ inch (1 cm.) deep in sterile soil, in individual 2-inch (5 cm.) pots. They should sprout anywhere between 2-8 weeks from planting asparagus seeds.
Seedlings are ready to transplant when they are 10-12 weeks old and all danger of frost in your area has passed. Space the transplants 18 inches (46 cm.) apart in rows set 3-6 inches (8-15 cm.) apart. If you want thinner spears, space the transplants 8-10 inches (20-25 cm.) apart, with the plant set 4 inches (10 cm.) deep. If you like thicker spears, plant them 12-14 inches (30-36 cm.) apart and set 6-8 inches (15-20 cm.) deep. Consider planting your new asparagus babies near your tomatoes. Asparagus repels nematodes that attack tomato plants while tomatoes repel asparagus beetles. A very symbiotic relationship, indeed.
As the plant grows, cover the crown with soil and keep it moist (one inch of water per week). Fertilize in the spring with 1-2 cups (250-473 ml.) of complete organic fertilizer per 10 foot (3 m.) of row and dig in gently. Remember, don’t harvest the plant until its third year; allow the plant to set ferns and redirect its energy back into the plant. Cut the ferns down to 2 inches (5 cm.) tall in the late fall.
In the plant’s third year, you can begin regularly harvesting the spears. The season usually lasts around 8-12 weeks. Cut the asparagus spears 1-2 inches (3-5 cm.) below the ground, and at least 2 inches (5 cm.) above the crown using a sharp knife or asparagus harvesting tool.
