The Gardener’s Answer
Hi again, Robert: It sounds like you will be eating a lot from your garden this year! Good for you. Asparagus is a long-lived perennial vegetable. As with any vegetable in the garden, fertile/nutrient-rich soil is essential for crop production. Asparagus will appreciate additional compost and fertilizer added to the soil at the time of planting. Each spring you can side-dress your veggies with 1 pound of a slow-release fertilizer with a ratio of 5-10-10 per 100 square feet. After growth begins and once again during the growing season, you can add ammonium nitrate at a rate of 10 Tbs. for each 10 feet of planting row. Compost is always beneficial to the soil. Keeping the soil evenly moist will allow available nutrients to be taken up through the roots. Mulch will help keep the soil evenly moist and will also help control potential weeds.
