Growing Asparagus All Season: A DIY Guide to Extended Harvest
Asparagus, that delicious harbinger of spring, doesn’t have to be a fleeting pleasure. With a little planning and some clever techniques, you can extend your asparagus harvest well beyond the typical spring window. I’m going to walk you through how to enjoy fresh asparagus spears for a much longer period, maximizing your garden’s bounty.
Understanding Asparagus Growth
Before we dive into the techniques, let’s quickly cover the basics of asparagus growth. Asparagus is a perennial plant, meaning it lives for many years. It grows from a crown, which is a mass of roots and buds. In the spring, these buds send up spears, which are the edible part we harvest. If left unharvested, these spears will fern out, producing foliage that nourishes the crown for the following year.
Key takeaway: The health of the crown directly impacts the following year’s harvest.
Extending the Harvest: The Strategies
Here’s the breakdown of the strategies we’ll use to achieve an extended asparagus harvest:
* Variety Selection: Choosing the right varieties can make a significant difference.
* Succession Planting: Staggering planting times ensures a continuous supply.
* Strategic Harvesting: Knowing when and how to harvest is crucial.
* Crown Management: Proper care of the crowns promotes healthy growth and future yields.
* Forced Asparagus: Growing asparagus indoors during the off-season.
Variety Selection: Choosing the Right Asparagus
Not all asparagus varieties are created equal. Some are earlier producers, while others are later. Selecting a mix of varieties can naturally extend your harvest window.
* Early Varieties: ‘Jersey Knight’ and ‘Millennium’ are known for their early production.
* Mid-Season Varieties: ‘Jersey Giant’ and ‘Purple Passion’ offer a good balance.
* Late Varieties: ‘Apollo’ tends to produce later in the season.
My recommendation: Plant a mix of ‘Jersey Knight’ and ‘Apollo’ to cover both ends of the spectrum.
Succession Planting: Staggering Your Planting Times
While asparagus is typically planted from crowns, you can use succession planting to your advantage. This involves planting new crowns at different times to create staggered production.
Important Note: Asparagus takes a few years to mature, so succession planting is a long-term strategy.
Planting New Crowns: A Step-by-Step Guide
1. Prepare the Soil: Asparagus needs well-drained soil that is rich in organic matter. Amend your soil with compost and aged manure. Aim for a pH of 6.5 to 7.5.
2. Dig Trenches: Dig trenches that are about 12 inches wide and 6-8 inches deep. Space the trenches about 4-5 feet apart.
3. Plant the Crowns: Place the asparagus crowns in the trenches, spacing them about 12-18 inches apart. Make sure the buds are facing upwards.
4. Cover the Crowns: Gently cover the crowns with about 2 inches of soil. As the spears emerge, gradually fill in the trench with more soil until it is level with the surrounding ground.
5. Water Thoroughly: Water the newly planted crowns well. Keep the soil consistently moist, but not waterlogged.
6. Mulch: Apply a layer of mulch around the plants to help retain moisture and suppress weeds.
7. Fertilize: Fertilize the asparagus plants with a balanced fertilizer in the spring.
Timing is Key: Plant some crowns in early spring and another batch a few weeks later. This will create a staggered production schedule.
Strategic Harvesting: Knowing When and How to Pick
The way you harvest asparagus can significantly impact the length of your harvest season.
* The First Year: Do not harvest any spears in the first year. This allows the plants to establish a strong root system.
* The Second Year: Harvest sparingly in the second year, only picking a few spears per plant.
* Subsequent Years: In subsequent years, you can harvest more heavily.
Harvesting Techniques:
1. Identify Harvestable Spears: Look for spears that are at least 6-8 inches tall and about as thick as your finger.
2. Harvesting Methods: You can either snap the spears off at ground level or cut them with a sharp knife. Snapping is generally preferred, as it avoids damaging the crown.
3. Harvesting Frequency: Harvest spears every day or every other day during the peak season.
4. Extending the Harvest: Stop harvesting when the spears become thin and spindly. This indicates that the plants need to replenish their energy reserves.
Pro Tip: Leaving some spears to fern out early in the season can help prolong the overall harvest.
Crown Management: Keeping Your Asparagus Healthy
Healthy crowns are essential for a long and productive harvest. Here’s how to keep your asparagus crowns thriving:
* Watering: Asparagus needs consistent moisture, especially during the growing season. Water deeply and regularly, especially during dry spells.
* Fertilizing: Fertilize your asparagus plants in the spring with a balanced fertilizer. You can also side-dress with compost or aged manure.
* Weed Control: Keep the asparagus bed free of weeds. Weeds compete with the asparagus for nutrients and water.
* Pest and Disease Control: Monitor your asparagus plants for pests and diseases. Common pests include asparagus beetles and aphids. Common diseases include rust and crown rot. Treat any problems promptly.
* Mulching: Apply a layer of mulch around the plants to help retain moisture, suppress weeds, and regulate soil temperature.
* Cutting Back Ferns: In the fall, after the ferns have turned brown, cut them back to ground level. This helps to prevent disease and pests from overwintering in the garden.
Important: Avoid over-harvesting, as this can weaken the crowns and reduce future yields.
Forced Asparagus: Bringing the Harvest Indoors
Forcing asparagus is a technique that allows you to harvest spears indoors during the off-season. This involves digging up mature crowns and replanting them in containers in a dark, cool place.
Forcing Asparagus: A Step-by-Step Guide
1. Select Mature Crowns: Choose asparagus crowns that are at least 3-4 years old.
2. Dig Up the Crowns: Carefully dig up the crowns in the fall, after the ferns have died back.
3. Prepare Containers: Choose large containers that are at least 12 inches deep and wide. Fill the containers with a well-draining potting mix.
4. Plant the Crowns: Plant the asparagus crowns in the containers, spacing them about 6 inches apart.
5. Water Thoroughly: Water the newly planted crowns well.
6. Provide Darkness: Place the containers in a dark, cool place, such as a basement or garage. The ideal temperature is around 50-60掳F (10-15掳C).
7. Water Regularly: Keep the soil consistently moist, but not waterlogged.
8. Harvest the Spears: After a few weeks, spears will begin to emerge. Harvest the spears when they are about 6-8 inches tall.
9. Discard the Crowns: After the harvest is complete, discard the crowns. They will not produce well again.
Important Note: Forcing asparagus is a one-time process. The crowns will be exhausted after the harvest.
Troubleshooting Common Asparagus Problems
Even with the best care, you might encounter some challenges. Here are a few common problems and how to address them:
* Thin Spears: This can be caused by over-harvesting, nutrient deficiencies, or drought. Make sure you are not harvesting too heavily, fertilize regularly, and water deeply during dry spells.
* Asparagus Beetles: These pests can damage the spears and foliage. Handpick the beetles or use an insecticidal soap.
* Rust: This fungal disease can cause orange or brown spots on the foliage. Improve air circulation and use a fungicide if necessary.
* Crown Rot: This fungal disease can cause the crowns to rot. Ensure good drainage and avoid overwatering.
Remember: Prevention is key. Healthy plants are less susceptible to pests and diseases.
Maximizing Your Asparagus Harvest: Additional Tips
Here are a few extra tips to help you get the most out of your asparagus patch:
* Soil Testing: Test your soil regularly to ensure that it has the proper pH and nutrient levels.
* Crop Rotation: Avoid planting asparagus in the same location year after year. This can help to prevent soilborne diseases.
* Companion Planting: Plant asparagus with companion plants such as tomatoes, basil, and parsley. These plants can help to deter

2. How important is soil preparation for growing asparagus all season?
Soil preparation is paramount. Asparagus needs well-drained soil that is rich in organic matter. Before planting, amend the soil with plenty of compost, well-rotted manure, or other organic amendments. Asparagus prefers a slightly acidic to neutral soil pH (around 6.5 to 7.0). A soil test can help you determine your soil’s pH and nutrient levels. If your soil is heavy clay, consider adding sand or other drainage-improving materials. Proper soil preparation ensures that your asparagus plants have the nutrients and drainage they need to thrive throughout the growing season.
3. What is succession planting, and how does it help extend the asparagus harvest?
Succession planting involves planting asparagus crowns at different times to stagger the harvest. You can plant some crowns in early spring, others a few weeks later, and even a third batch a few weeks after that. This creates a continuous supply of asparagus spears as the earlier plantings begin to slow down. Be sure to label your plantings so you know when each batch was planted. This technique is particularly effective when combined with different asparagus varieties that have varying maturity dates.
4. How often should I water my asparagus plants?
Asparagus needs consistent moisture, especially during the growing season. Water deeply and regularly, especially during dry spells. Aim to keep the soil consistently moist but not waterlogged. Mulching around the plants can help retain moisture and suppress weeds. The frequency of watering will depend on your climate and soil type. Check the soil moisture regularly and adjust your watering schedule accordingly.
5. What are some common asparagus pests and diseases, and how can I prevent them?
Asparagus beetles are a common pest that can damage the ferns and spears. Handpicking the beetles and larvae is an effective control method. You can also use insecticidal soap or neem oil. Asparagus rust is a fungal disease that can cause orange pustules on the ferns. Ensure good air circulation around the plants and avoid overhead watering to prevent rust. Remove and destroy any infected ferns. Choosing rust-resistant varieties can also help. Regularly inspect your plants for signs of pests or diseases and take action promptly to prevent them from spreading.
6. How do I know when to stop harvesting asparagus spears?
It’s crucial to stop harvesting asparagus spears at the right time to allow the plants to replenish their energy reserves for the following year. Generally, you should stop harvesting when the spears become thinner and less vigorous. This usually occurs in late spring or early summer. Allow the remaining spears to develop into ferns, which will photosynthesize and store energy in the roots. Avoid cutting back the ferns until they turn brown in the fall or winter.
7. Can I grow asparagus in containers?
Yes, you can grow asparagus in containers, but it requires careful planning and maintenance. Choose a large container (at least 18 inches in diameter) with good drainage. Use a high-quality potting mix and amend it with compost. Water regularly and fertilize every few weeks. Container-grown asparagus may not be as productive as plants grown in the ground, but it’s a viable option for gardeners with limited space.
8. How long does it take for asparagus plants to mature and produce a harvest?
Asparagus plants typically take two to three years to mature and produce a significant harvest. During the first year, allow the plants to establish themselves and focus on developing a strong root system. In the second year, you can harvest a few spears for a short period. By the third year, you should be able to enjoy a more substantial harvest. Patience is key when growing asparagus!
9. What are some good companion plants for asparagus?
Companion planting can help improve the health and productivity of your asparagus plants. Some good companion plants include tomatoes, basil, parsley, marigolds, and nasturtiums. Tomatoes can help deter asparagus beetles, while basil can repel other pests. Marigolds and nasturtiums can attract beneficial insects that prey on asparagus pests. Avoid planting asparagus near onions, garlic, or other alliums, as they can inhibit asparagus growth.
10. How do I overwinter my asparagus plants?
In the fall or winter, after the ferns have turned brown, cut them back to the ground. Apply a layer of mulch to protect the crowns from frost. In colder climates, you may need to provide additional protection, such as covering the plants with a tarp or blanket. In the spring, remove the mulch and fertilize the plants to encourage new growth.
