Growing Asparagus at Home: A Beginner’s Guide
Asparagus, that delicious and slightly grassy spring vegetable, is surprisingly easy to grow at home, even if you don’t have a huge garden! It’s a long-term investment, as it takes a few years to establish, but the rewards are well worth the wait. Imagine fresh, homegrown asparagus spears gracing your plate every spring – it’s a dream come true! I’m going to walk you through everything you need to know to successfully grow asparagus in your own backyard.
Choosing the Right Asparagus Variety
First things first, you need to decide which asparagus variety is right for you. There are male and female varieties, and some newer hybrids that are all-male. Male varieties are generally preferred because they don’t produce seeds, which means they put more energy into spear production. Here are a few popular choices:
* Jersey Knight: A widely popular all-male hybrid known for its high yield and disease resistance. This is a great choice for beginners.
* Jersey Giant: Another all-male hybrid, similar to Jersey Knight but slightly larger spears.
* Purple Passion: A unique variety with beautiful purple spears that turn green when cooked. It’s sweeter and more tender than green varieties.
* Mary Washington: An older, reliable variety that’s been around for years. It’s a good choice if you’re looking for something tried and true.
I personally recommend starting with Jersey Knight or Jersey Giant. They’re reliable, productive, and relatively easy to grow.
Preparing the Asparagus Bed
Asparagus needs a well-drained, sunny location with plenty of space. These plants are going to be in the same spot for 15-20 years, so it’s crucial to get the soil right from the start.
* Sunlight: Asparagus needs at least 6-8 hours of direct sunlight per day.
* Soil: Asparagus prefers well-drained, sandy loam soil with a pH between 6.5 and 7.0. If your soil is heavy clay, you’ll need to amend it with plenty of organic matter.
* Space: Asparagus plants need plenty of space to spread out. Allow at least 4 feet between rows and 12-18 inches between plants within a row.
Step-by-Step Bed Preparation:
1. Clear the Area: Remove all weeds, grass, rocks, and debris from the planting area. This is a crucial step, as weeds can be a major problem for young asparagus plants. I like to use a garden fork to loosen the soil and pull out any stubborn roots.
2. Soil Testing: It’s a good idea to get your soil tested to determine its pH and nutrient levels. You can usually get a soil test kit from your local garden center or agricultural extension office. This will help you determine what amendments you need to add.
3. Amend the Soil: Based on your soil test results, amend the soil with organic matter such as compost, well-rotted manure, or peat moss. This will improve drainage, aeration, and fertility. I usually add a generous layer of compost (about 4-6 inches) and work it into the soil with a garden fork.
4. Adjust the pH: If your soil is too acidic (pH below 6.5), add lime to raise the pH. If it’s too alkaline (pH above 7.0), add sulfur to lower the pH. Follow the instructions on the product label for application rates.
5. Dig a Trench: Dig a trench that is about 12 inches wide and 6-8 inches deep. This is where you’ll plant your asparagus crowns.
6. Create a Ridge: In the bottom of the trench, create a ridge of soil down the center. This ridge will support the asparagus crowns and help with drainage.
Planting Asparagus Crowns
Asparagus is typically grown from crowns, which are one-year-old dormant plants. You can purchase crowns from a garden center or online nursery.
* When to Plant: The best time to plant asparagus crowns is in early spring, as soon as the soil can be worked.
* Choosing Crowns: Look for healthy crowns that are plump and have plenty of roots. Avoid crowns that are dry, shriveled, or moldy.
Planting Instructions:
1. Soak the Crowns: Before planting, soak the asparagus crowns in water for about 30 minutes. This will help rehydrate them and encourage root growth.
2. Place the Crowns: Place the asparagus crowns on top of the ridge in the trench, spacing them about 12-18 inches apart. Spread the roots out evenly around the crown.
3. Cover the Crowns: Cover the crowns with about 2-3 inches of soil. Gently pat the soil down around the crowns.
4. Water Thoroughly: Water the newly planted crowns thoroughly.
5. Gradually Fill the Trench: As the asparagus spears emerge, gradually fill in the trench with soil. This will encourage the crowns to develop a strong root system. By the end of the first growing season, the trench should be completely filled in.
Caring for Your Asparagus Patch
Asparagus requires regular care to thrive. Here’s what you need to do:
* Watering: Asparagus needs consistent moisture, especially during the first year. Water deeply whenever the soil feels dry to the touch.
* Weeding: Keep the asparagus bed free of weeds. Weeds can compete with asparagus for nutrients and water. Hand-pull weeds regularly or use a hoe to cultivate the soil.
* Fertilizing: Fertilize asparagus in early spring and again after the harvest season. Use a balanced fertilizer such as 10-10-10 or a fertilizer specifically formulated for vegetables. Follow the instructions on the product label for application rates. I also like to side-dress with compost throughout the growing season.
* Mulching: Apply a layer of mulch around the asparagus plants to help retain moisture, suppress weeds, and regulate soil temperature. Organic mulches such as straw, wood chips, or shredded leaves are excellent choices.
* Pest and Disease Control: Asparagus is relatively pest and disease resistant, but it can be susceptible to asparagus beetles and fungal diseases. Inspect your plants regularly for signs of pests or diseases. If you find any problems, treat them promptly with an appropriate insecticide or fungicide. I prefer to use organic pest control methods whenever possible.
Harvesting Asparagus
This is the part you’ve been waiting for! But patience is key. You shouldn’t harvest any asparagus spears during the first two years after planting. This allows the plants to establish a strong root system.
* Year 1 & 2: Resist the urge to harvest! Let the spears grow into ferns. This is crucial for building the plant’s energy reserves.
* Year 3: You can harvest lightly for a few weeks.
* Year 4 and Beyond: You can harvest for 6-8 weeks each spring.
Harvesting Tips:
1. Harvest When Spears are 6-8 Inches Tall: Harvest the spears when they are about 6-8 inches tall and the tips are still tightly closed.
2. Cut or Snap the Spears: You can either cut the spears at ground level with a sharp knife or snap them off by hand. I prefer to snap them off, as this is less likely to damage the crown.
3. Harvest Regularly: Harvest the spears every day or two during the peak of the season. This will encourage the plants to produce more spears.
4. Stop Harvesting When Spears Become Thin: Stop harvesting when the spears become thin and spindly. This indicates that the plants are starting to run out of energy.
5. Let the Ferns Grow: After the harvest season, let the remaining spears grow into ferns. These ferns will photosynthesize and provide energy for the plants to store in their roots for the next year’s harvest.
Winter Care
In the fall, after the ferns have turned brown, cut them back to about 2 inches above the ground. This will help prevent diseases from overwintering in the ferns. You can also apply a layer of compost or well-rotted manure around the plants to provide nutrients for the winter.
* Cut Back Ferns: Once the ferns turn brown in the fall, cut them back to a few inches above the ground.
* Apply Compost: Add a layer of compost around the base of the plants to provide nutrients and protect the roots from the cold.
* Mulch (Optional): In colder climates, you can add a layer of mulch to provide extra insulation.
Troubleshooting
Even with the best care, you may encounter some problems when growing asparagus. Here are a few common issues and how to deal with them:
* Asparagus Beetles: These small, colorful beetles

Frequently Asked Questions (FAQ)
How long does it take to grow asparagus from seed?
Growing asparagus from seed requires patience. It typically takes 2-3 years from seed to harvestable spears. The first year is focused on developing a strong root system (the crown). You can start seeds indoors in late winter or early spring, transplanting them outdoors after the last frost. Alternatively, you can sow seeds directly into the ground in spring. Be sure to provide consistent moisture and weed control during the initial stages of growth. While starting from seed is more economical, it requires significantly more time compared to planting crowns.
What are asparagus crowns, and why are they recommended?
Asparagus crowns are one-year-old or two-year-old dormant root systems of asparagus plants. They offer a significant head start compared to starting from seed. Planting crowns reduces the waiting time to harvest by at least a year. When planting crowns, dig a trench, spread out the roots, and cover them with soil. As the plants grow, gradually fill in the trench. Crowns are readily available at nurseries and garden centers, making them a convenient option for most home gardeners.
What kind of soil is best for growing asparagus?
Asparagus thrives in well-drained, sandy loam soil with a pH between 6.5 and 7.5. Good drainage is crucial to prevent root rot. Before planting, amend the soil with plenty of organic matter, such as compost or aged manure, to improve its fertility and drainage. Avoid heavy clay soils, as they can become waterlogged and inhibit asparagus growth. If you have clay soil, consider growing asparagus in raised beds or containers.
How much sunlight does asparagus need?
Asparagus requires at least 6-8 hours of direct sunlight per day to thrive. Choose a planting location that receives ample sunlight throughout the growing season. Insufficient sunlight can result in weak, spindly spears and reduced yields.
How often should I water asparagus?
Asparagus needs consistent moisture, especially during the growing season. Water deeply and regularly, ensuring that the soil remains moist but not waterlogged. Avoid overhead watering, as it can promote fungal diseases. A soaker hose or drip irrigation system is ideal for delivering water directly to the roots. During dry periods, increase the frequency of watering.
When is the best time to harvest asparagus?
The harvesting season typically begins in the spring, usually around April or May, depending on your climate. In the first year after planting crowns, refrain from harvesting any spears to allow the plants to establish themselves. In the second year, you can harvest lightly for a few weeks. From the third year onwards, you can harvest for 6-8 weeks. Harvest spears when they are 6-8 inches tall and have tightly closed tips. Snap or cut the spears off at ground level.
How do I care for asparagus after the harvesting season?
After the harvesting season, allow the asparagus ferns to grow and mature. These ferns are essential for replenishing the plant’s energy reserves for the following year. Fertilize the asparagus bed with a balanced fertilizer or compost to provide essential nutrients. Remove any weeds that may compete with the asparagus plants. In the fall, after the ferns have turned brown, cut them back to ground level.
What are some common asparagus pests and diseases?
Asparagus beetles are a common pest that can damage asparagus spears and ferns. Handpicking the beetles or using insecticidal soap can help control infestations. Asparagus rust is a fungal disease that can cause orange pustules on the ferns. Ensure good air circulation and avoid overhead watering to prevent rust. Crop rotation and disease-resistant varieties can also help minimize the risk of rust.
Can I grow asparagus in containers?
Yes, you can grow asparagus in containers, but it requires a large container (at least 18 inches in diameter and 24 inches deep) to accommodate the extensive root system. Use a well-draining potting mix and provide regular watering and fertilization. Container-grown asparagus may not be as productive as asparagus grown in the ground, but it’s a viable option for those with limited space.
How long will an asparagus patch last?
With proper care, an asparagus patch can last for 15-20 years or even longer. Regular fertilization, weed control, and pest management are essential for maintaining a healthy and productive asparagus bed. By following these guidelines, you can enjoy a bountiful harvest of fresh asparagus for many years to come.
