Growing Asparagus in the Ground: A Complete Guide


Asparagus is a delicious and nutritious vegetable that many gardeners love to grow. If you’re an avid gardener, you may have asked yourself, “Does asparagus grow in the ground?” The answer is yes! Asparagus is typically grown in the ground, where it can develop its long, spear-like edible stalks.

When planting asparagus, it’s important to choose a sunny spot in your garden with well-drained soil. Asparagus prefers soil that is free from weeds and rich in organic matter. Before planting, you’ll want to prepare the bed by removing any weeds and adding compost or other organic fertilizers.

Asparagus can be planted from seed or by using crowns, which are dormant, aged plants. Planting asparagus crowns is the quicker option, as they will reach a harvestable size in just a few years. However, if you prefer to start from seed, be aware that it will take longer for your asparagus to reach maturity.

One of the key factors in successfully growing asparagus in the ground is fertilization. Asparagus plants have high nutrient needs and benefit from regular fertilization. A balanced fertilizer with a nitrogen-phosphorous-potassium (NPK) ratio of 10-10-10 or 12-12-12 can be applied in early spring, just as the ferns begin to emerge from the ground.

Asparagus is also susceptible to diseases and pests, so proper care is essential. Regularly check your plants for signs of common asparagus diseases, such as crown rot or rust. If you spot any problems, a quick search on Google or reaching out to an experienced gardener can help you find solutions and prevent further damage.

In conclusion, asparagus does indeed grow in the ground and can be a rewarding addition to your garden. With proper preparation, fertilization, and care, you’ll soon be enjoying the delicious taste of homegrown asparagus!

How to Grow Asparagus in Your Garden

Growing asparagus in your garden can be a rewarding experience. Not only does it provide you with a delicious and nutritious vegetable, but it can also add beauty to your garden with its feathery fronds. Here are some tips on how to successfully grow asparagus in your garden.

Prepare the Bed: Before planting the asparagus crowns, it is important to prepare the bed properly. Choose a sunny spot with well-drained soil. Asparagus prefers soil with a pH level between 6.5 and 7.5. Turn over the soil using a sharp knife or garden fork to ensure good drainage and remove any weeds.

Plant the Crowns: Asparagus is typically grown from crowns, which are one-year-old asparagus plants. Dig trenches about 6 inches deep and 12 inches wide. Place the crowns in the trenches, spacing them about 18 inches apart in rows that are 4 to 5 feet apart. Cover the crowns with about 2 inches of soil and water them well.

Care for the Plants: As the asparagus plants grow, it is important to provide them with proper care to ensure healthy growth and productivity. Keep the bed well-irrigated, especially during dry periods. Watch out for common pests like the asparagus beetle and follow instructions on how to deal with them. Growing asparagus in raised beds can help prevent some pest and disease problems.

Harvest and Store: After the asparagus plants have been growing for two years, you can start harvesting the spears. Use a sharp knife to cut the spears just below the soil surface when they are about 6-8 inches tall. Harvesting them early in the season will encourage further cropping. Be sure to leave any spears that appear thin or unhealthy. After harvesting, store the asparagus in the refrigerator, wrapped in a damp paper towel, for up to a week.

Watch for Winter Care: As winter approaches, it is important to take steps to protect your asparagus plants. Cut back the fronds to about 2 inches above the ground. This will help prevent diseases and make it easier to spot any new growth in the spring. You can also add a layer of mulch or compost around the crowns to provide insulation.

Enjoy the Harvest: Asparagus can be cooked in many ways and is a delicious addition to any meal. Whether grilled, roasted, or sautéed, asparagus retains its flavor and quality. It pairs well with a variety of other ingredients and can be enjoyed fresh or preserved for later use. Watch the video below for further instructions on how to cook asparagus.

In conclusion, growing asparagus in your garden requires some initial preparation and care, but the rewards are well worth it. With the right planting and maintenance, you can enjoy a bountiful asparagus harvest year after year.

When it comes to growing asparagus, choosing the right varieties can provide you with the best productivity and flavor. There are several recommended varieties available that are tolerant to various climates and soil conditions.

One popular variety is the “Jersey Giant”, which is known for its square and healthy spears. It is a male hybrid variety that can be planted with other varieties to ensure better fertilization and growing. Another popular variety is “Purple Passion”, which has attractive, dark purple spears that turn green when cooked. It is a very productive variety and is also resistant to diseases and pests.

If you prefer a shorter growing period, “Mary Washington” is a good choice. This variety is best for in-house gardening and has a high tolerance to frost. “UC 157 F1” is another widely grown variety that appears early in the season and can be harvested over a long period.

For areas where the asparagus beetle is a problem, “Millennium” is a recommended variety. It is resistant to beetle infestations and produces large and tasty spears. “Pacific Purple” is another good choice for preventing beetle damage, as it has strong ferns that protect the plants from the larvae.

In general, most asparagus varieties require well-drained soils and full sun. They need regular fertilization and proper care to ensure healthy growth. If you’re unsure about which variety to choose, it’s a good idea to consult with a local gardener or search for information online.

When it comes to harvesting asparagus, it’s important to know the proper techniques. Asparagus spears should be cut or snapped off when they reach about 6-8 inches in length. This allows the remaining spears to grow and develop properly. Harvesting can begin after the second year of planting, and it is recommended to harvest lightly during the first year to allow the plants to establish themselves.

If you have a smaller space or limited garden area, you can grow asparagus in containers. This allows for easier maintenance and ensures that the plants won’t take over your garden. Asparagus can also be grown from seeds, although it does take longer for the plants to mature compared to planting crowns.

After harvesting, it’s important to store the asparagus properly. The spears can be stored in the refrigerator for up to a week by wrapping the bottoms of the spears in a damp paper towel and placing them in a plastic bag. For longer storage, the asparagus can be blanched and frozen.

In conclusion, choosing the right variety of asparagus is crucial for successful and bountiful growth. Consider factors such as climate, soil conditions, and personal preferences when selecting the varieties for your garden. With proper care and attention, you can enjoy a healthy and delicious harvest of asparagus.

How to Grow Asparagus

Growing asparagus can be a rewarding experience for any vegetable gardener. It is a perennial plant which can produce a bountiful harvest for many years if properly cared for. Here is a comprehensive guide on how to grow asparagus.

Planting: Asparagus is typically planted in early spring or late autumn in a weed-free and well-draining soil. The plant is frost-tolerant and can survive in temperatures as low as 20 degrees Fahrenheit.

Spacing: Asparagus plants should be spaced about 18 to 24 inches apart in rows that are around 4 feet apart. This spacing allows the plants to grow properly and prevents overcrowding.

Fertilization: Asparagus plants require regular fertilization to ensure healthy growth and high yields. A balanced fertilizer can be applied during the planting period and then again a few weeks after. Additional fertilization may be needed throughout the growing season, depending on the state of the soil.

Harvesting: Asparagus can be harvested in the second year after planting. The spears are typically ready to be picked when they are around 6 to 8 inches tall. Using a sharp knife, cut the spears above the ground level to prevent any damage to the plant.

Storing: After harvesting, it is important to store the asparagus properly to maintain its freshness and flavor. The best way to store asparagus is by keeping them in a plastic bag with a damp paper towel. They can be stored in the refrigerator for up to a week.

Many growers choose to grow asparagus in raised beds or containers, as they offer better control over soil quality and drainage. However, asparagus can also be grown directly in the garden with proper preparation and care.

If you have any questions about growing asparagus or need expert advice, be sure to ask a local gardening store or an experienced gardener. They will be able to provide specific information for your region and help you troubleshoot any problems you may encounter.

With its delicious flavor and high yield potential, growing asparagus can be a rewarding experience for any gardener. So, why wait? Start growing your own asparagus and enjoy the fresh harvest year after year!


When it comes to growing asparagus, soil is crucial. It is recommended to turn the soil over a foot deep and remove any rocks or other debris. This helps to ensure that the asparagus crowns can easily penetrate the soil and establish themselves.

Asparagus prefers sandy or loamy soil that is well drained. It does best in soil with a pH level of 6.5 to 7, which is slightly acidic to neutral. The soil should also be rich in organic matter to provide the necessary nutrients for the plants to thrive.

Before planting, it’s important to prepare the soil properly. Weed the area thoroughly and remove any roots or other plant material that may interfere with the growth of the asparagus. You can also consider using a knife to remove any larvae or pests that may be present in the soil.

The asparagus bed should be about 6 feet wide and raised into a mound. This helps to keep the soil warm and well-drained. It also keeps the fronds and developing spears above ground level, reducing the risk of frost damage.

So, how do you plant asparagus in the ground? First, make sure to create rows with a spacing of about 18 to 24 inches apart. Each crown should be planted around 6 to 8 inches deep, with the root system spread out. After planting, make sure to water the crowns well.

Once the asparagus plants are established, they require regular care. It is important to keep the bed weed-free, as weeds can compete for nutrients and water. Frequent watering, about 1 to 1.5 inches per week, is recommended, especially during dry periods.

To further ensure the health of your asparagus plants and promote good cropping, it is important to feed them. Apply a balanced fertilizer around the plants early in the growing season. This will provide the necessary nutrients for the plants to grow and produce spears.

Asparagus beetles can be a problem, especially in the Pacific Northwest. These pests can damage the fronds and eat the developing spears. To control them, you can handpick the beetles and their larvae. Regularly checking the plants for any signs of infestation is recommended.

In colder climates where winter temperatures frequently drop below freezing, it is important to properly prepare the asparagus for winter. After the first frost, remove the fronds and cut them down to ground level. Apply a layer of mulch to protect the crowns from freezing temperatures.

Overall, soil preparation, planting, and caring for asparagus in the ground requires attention to detail and regular maintenance. By following these recommended steps, you can ensure that your asparagus plants grow healthy and produce a bountiful harvest.
