Growing asparagus is an exercise in patience. You might find yourself waiting three years for the first tender shoots, but the reward is well worth the wait. With proper care, asparagus plants can provide a bounty of delicious, nutritious spears for up to 20 years. Choosing the Right Spot
Asparagus plants require full sun to produce well, so select a spot that receives at least six hours of direct sunlight per day. In addition to sunlight, asparagus needs well-draining soil with a pH between 6.5 and 7.0. You can achieve this by incorporating a generous helping of compost or well-rotted manure into the soil before planting.
- Compost or well-rotted manure adds fertility and nutrients to the soil, creating a rich environment for asparagus plants to thrive.
- Make sure the soil is well-draining to prevent waterlogged conditions that can lead to root rot and other problems.
- Asparagus prefers a slightly acidic to neutral soil pH, between 6.5 and 7.0, for optimal growth.
Planting Crowns or Seeds
While it is possible to grow asparagus from seeds, planting year-old crowns is the recommended method. Crowns are dormant roots that have been harvested from mature asparagus plants. They provide a head start by reducing the time to your first harvest by a year.
- Plant crowns in early spring, after the ground has thawed and the danger of frost has passed.
- Plant crowns 12-18 inches apart, in trenches that are 12-18 inches wide and 6-12 inches deep.
- Spread the roots over the bottom of the trench, cover with 2-3 inches of soil, and water well.
Establishing the Plant
After planting crowns, add more soil gradually until the crowns are fully buried and the trench is filled in. Then apply mulch to retain moisture and suppress weeds.
| Step | Description |
|---|---|
| Step 1: Prepare the Bed | Clear the area of weeds and debris, and create a trench 12-18 inches wide and 6-12 inches deep. |
| Step 2: Plant the Crown | Plant the crown 12-18 inches apart, spreading the roots over the bottom of the trench, and cover with 2-3 inches of soil. |
| Step 3: Add Soil Gradually | Fill in the trench, adding more soil gradually until the crowns are fully buried. |
| Step 4: Apply Mulch | Apply a layer of mulch to retain moisture and suppress weeds. |
Harvesting and Care
Asparagus plants are ready to harvest in the spring, when stalks are 6-10 inches tall and about as thick as a pencil. Use a sharp knife to cut each stalk slightly below the soil line, taking care not to damage emerging stalks.
- Harvest asparagus for roughly six weeks, depending on your climate.
- Avoid harvesting after the six-week period, as this can damage the plant and reduce future yields.
- Leave the remaining stalks in place to store energy for the following year’s harvest.
“I can harvest asparagus until the beginning of July in my suburban New York garden. It’s a feeling of satisfaction and accomplishment, knowing that I’ve nurtured these plants from seed to maturity.” – Jessica Damiano
Companion Plants
Onion and garlic can stunt asparagus, so it’s best to avoid planting them nearby. Instead, consider planting companion plants like marigolds or nasturtiums, which can help repel pests and attract beneficial insects.

- Companion Planting:
- The practice of growing different plants together to improve growth, health, and productivity.
-
- Beneficial Insects:
- Insects that help pollinate plants, control pests, or provide other benefits to the garden.
Conclusion:
Growing asparagus is a rewarding experience that requires patience, dedication, and proper care. With these guidelines, you’ll be well on your way to growing delicious, nutritious spears for years to come. So why not give it a try? Plant some crowns, tend to your asparagus, and enjoy the satisfaction of harvesting your own fresh asparagus.
