Growing Asparagus Indoors: A Complete DIY Guide
Hey there, fellow plant enthusiasts! Ever dreamt of harvesting your own fresh asparagus spears right from the comfort of your home? Well, dream no more! While asparagus is traditionally an outdoor crop, with a little know-how and some patience, you can absolutely cultivate this delicious vegetable indoors. I’m going to walk you through the entire process, from choosing the right variety to harvesting your first spears. Let’s get started!
Choosing the Right Asparagus Variety
Not all asparagus varieties are created equal, especially when it comes to indoor growing. You’ll want to opt for varieties that are known for their compact size and adaptability.
* ‘UC 157’: This is a popular and reliable choice, known for its high yield and disease resistance. It’s a great option for beginners.
* ‘Jersey Knight’: Another excellent variety, ‘Jersey Knight’ is known for its early production and tolerance to various growing conditions.
* ‘Purple Passion’: If you’re looking for something a little different, ‘Purple Passion’ offers beautiful purple spears with a sweeter flavor. Keep in mind that purple varieties might require slightly more light.
Getting Started: Planting Asparagus Crowns
Asparagus is typically grown from crowns, which are one-year-old plants. You can purchase these from nurseries or online retailers. Avoid using seeds, as they take much longer to mature.
1. Gather Your Supplies: You’ll need the following:
* Asparagus crowns (choose your variety!)
* Large containers (at least 12 inches in diameter and 18 inches deep)
* High-quality potting mix (a well-draining mix is crucial)
* Perlite or vermiculite (to improve drainage)
* Slow-release fertilizer (formulated for vegetables)
* Watering can or hose
* Grow lights (if you don’t have a sunny location)
2. Prepare the Containers: Fill your containers with the potting mix, leaving about 4 inches of space at the top. Mix in perlite or vermiculite to improve drainage. I usually go for a 2:1 ratio of potting mix to perlite.
3. Plant the Crowns: Create a small mound of soil in the center of each container. Gently spread the roots of the asparagus crown over the mound. The crown should sit about 6 inches below the surface of the soil.
4. Cover the Roots: Carefully cover the roots with soil, making sure the crown is still positioned correctly. Gently pat down the soil.
5. Water Thoroughly: Water the newly planted crowns thoroughly until water drains from the bottom of the container. This helps settle the soil and encourages root growth.
6. Fertilize: Apply a slow-release fertilizer according to the package instructions. This will provide the asparagus with the nutrients it needs to get started.
Providing the Right Environment
Asparagus needs the right environment to thrive indoors. This includes adequate light, temperature, and humidity.
1. Light: Asparagus requires at least 6-8 hours of direct sunlight per day. If you don’t have a sunny location, you’ll need to supplement with grow lights. I recommend using full-spectrum LED grow lights, positioned about 12-18 inches above the plants.
2. Temperature: Asparagus prefers temperatures between 65-75°F (18-24°C) during the day and slightly cooler temperatures at night. Avoid placing the plants near drafts or heating vents.
3. Humidity: Asparagus prefers moderate humidity levels. If your home is dry, you can increase humidity by using a humidifier, placing the containers on a tray filled with pebbles and water, or misting the plants regularly.
4. Watering: Water the asparagus regularly, keeping the soil consistently moist but not waterlogged. Allow the top inch of soil to dry out between waterings. Overwatering can lead to root rot, so be careful!
5. Fertilizing: Fertilize the asparagus every 4-6 weeks with a balanced liquid fertilizer. Follow the package instructions carefully.
Caring for Your Asparagus Plants
Once your asparagus plants are established, you’ll need to provide ongoing care to ensure healthy growth and a good harvest.
1. Weeding: Keep the containers free of weeds. Weeds can compete with the asparagus for nutrients and water.
2. Pest Control: Monitor your plants regularly for pests such as aphids, spider mites, and asparagus beetles. If you find any pests, treat them with an appropriate insecticide or insecticidal soap. I prefer using organic options whenever possible.
3. Support: As the asparagus ferns grow taller, they may need support. You can use stakes or a trellis to keep them from falling over.
4. Dormancy: Asparagus requires a period of dormancy each year to rest and rejuvenate. In the fall, the ferns will start to turn yellow and brown. At this point, stop watering and fertilizing the plants. Cut the ferns back to the soil level and move the containers to a cool, dark location for 2-3 months. This simulates the winter season. After the dormancy period, bring the containers back to their sunny location and resume watering and fertilizing.
Harvesting Your Asparagus Spears
The most exciting part! But patience is key.
1. First Year: Do not harvest any spears during the first year. This allows the plants to establish a strong root system.
2. Second Year: You can harvest a few spears during the second year, but only for a short period of time (2-3 weeks).
3. Third Year and Beyond: In the third year and beyond, you can harvest spears for a longer period of time (6-8 weeks).
4. Harvesting Technique: Harvest the spears when they are about 6-8 inches tall and about as thick as your finger. Use a sharp knife to cut the spears at soil level.
5. Post-Harvest Care: After harvesting, continue to water and fertilize the plants to encourage further growth.
Troubleshooting Common Problems
Even with the best care, you may encounter some problems when growing asparagus indoors. Here are some common issues and how to address them:
* Yellowing Ferns: This can be caused by overwatering, underwatering, nutrient deficiencies, or pests. Check the soil moisture and adjust your watering schedule accordingly. Fertilize the plants with a balanced fertilizer. Inspect the plants for pests and treat them as needed.
* Thin Spears: This can be caused by insufficient light, nutrient deficiencies, or overcrowding. Make sure the plants are getting enough light. Fertilize the plants with a balanced fertilizer. If the plants are overcrowded, you may need to divide them.
* Root Rot: This is caused by overwatering. Make sure the soil is well-draining and avoid overwatering. If you suspect root rot, you may need to repot the plants in fresh soil.
* Pests: Asparagus is susceptible to various pests, including aphids, spider mites, and asparagus beetles. Inspect the plants regularly for pests and treat them with an appropriate insecticide or insecticidal soap.
Extending Your Harvest
Want to keep the asparagus coming? Here are a few tips:
* Succession Planting: Plant new crowns every few weeks to extend your harvest season.
* Cold Frames: Use cold frames to protect your plants from frost and extend the growing season.
* Variety Selection: Choose varieties that mature at different times to extend your harvest.
Enjoying Your Homegrown Asparagus
Now that you’ve successfully grown your own asparagus indoors, it’s time to enjoy the fruits (or rather, vegetables) of your labor! Freshly harvested asparagus is incredibly delicious and versatile. You can steam it, grill it, roast it, or add it to salads, soups, and omelets.
Here are a few of my favorite asparagus recipes:
* Roasted Asparagus with Parmesan Cheese: Toss asparagus spears with olive oil, salt, pepper, and grated Parmesan cheese. Roast at 400°F (200°C) for 10-15 minutes, or until tender-crisp.
* Grilled Asparagus with Lemon: Grill asparagus spears over medium heat for 5-7 minutes, or until tender-crisp. Drizzle with lemon juice and olive oil.
* Asparagus and Goat Cheese Frittata: Sauté asparagus spears with onions and garlic. Whisk eggs with milk, salt, and pepper. Pour the egg mixture over the asparagus and onions. Crumble goat cheese over the top. Bake at 350°F (175°C) for 20-25 minutes, or until set.
Growing asparagus indoors can be a rewarding experience. With a little patience and care, you can enjoy fresh, delicious asparagus spears year-round. Happy gardening!

Frequently Asked Questions (FAQ)
What is the best time of year to plant asparagus crowns?
The ideal time to plant asparagus crowns is in early spring, as soon as the ground can be worked. This allows the crowns to establish themselves before the heat of summer arrives. In warmer climates, fall planting may also be successful. Avoid planting during periods of heavy frost or extreme heat.
How long does it take for asparagus to produce a harvest?
Patience is key when growing asparagus. It typically takes two to three years from planting crowns to harvest your first spears. During the first year, allow the plants to establish a strong root system. In the second year, you can harvest a few spears, but limit the harvest to a week or two. By the third year, you can enjoy a more substantial harvest, typically lasting for six to eight weeks.
What kind of soil does asparagus need?
Asparagus thrives in well-drained, fertile soil with a pH between 6.5 and 7.5. Amend the soil with plenty of organic matter, such as compost or well-rotted manure, to improve drainage and fertility. Avoid heavy clay soils, as they can lead to root rot. If your soil is acidic, add lime to raise the pH.
How much sun does asparagus need?
Asparagus requires at least six to eight hours of direct sunlight per day. 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?
Water asparagus regularly, especially during dry periods. Aim to keep the soil consistently moist but not waterlogged. Water deeply and less frequently, rather than shallowly and more often, to encourage deep root growth. Mulching around the plants can help retain moisture and suppress weeds.
What are common asparagus pests and diseases?
Asparagus beetles are a common pest that can damage the spears and foliage. Handpicking the beetles or using insecticidal soap can help control infestations. Asparagus rust is a fungal disease that can cause orange pustules on the stems and foliage. Ensure good air circulation and avoid overhead watering to prevent rust. Remove and destroy any infected plants. Fusarium wilt is another fungal disease that can cause yellowing and wilting of the plants. Choose disease-resistant varieties and practice crop rotation to minimize the risk of Fusarium wilt.
How do I harvest asparagus?
Harvest asparagus spears when they are about 6 to 8 inches tall and about as thick as your finger. Use a sharp knife to cut the spears at ground level. Avoid damaging the crown or surrounding spears. Harvest spears regularly during the harvest season to encourage continued production.
How do I care for asparagus after the harvest?
After the harvest season, allow the asparagus ferns to grow and mature. These ferns will produce energy that will be stored in the roots for the following year’s growth. Fertilize the plants with a balanced fertilizer to replenish nutrients. Cut back the ferns to ground level in late fall or early winter after they have turned brown.
Can I grow asparagus in containers?
Yes, asparagus can be grown in containers, but it requires a large pot (at least 18 inches deep and wide) and a high-quality potting mix. Container-grown asparagus may not produce as abundantly as in-ground plants, but it’s a viable option for those with limited space. Ensure the container has good drainage and provide consistent watering and fertilization.
What are some good companion plants for asparagus?
Several plants can benefit asparagus when grown nearby. Tomatoes, basil, parsley, and marigolds are all good companion plants that can help deter pests and enhance growth. Avoid planting asparagus near onions, garlic, or potatoes, as they can inhibit growth.
How long will my asparagus plants last?
With proper care, asparagus plants can last for 15 to 20 years or even longer. The key is to provide them with the right growing conditions, protect them from pests and diseases, and harvest them properly. Regular fertilization and soil amendments will also help prolong the life of your asparagus plants.
