Key Takeaways
1. The best time to plant asparagus in Missouri is in early spring, ideally in March or April when the soil temperature reaches around 50 to 70 degrees Fahrenheit.
2. Prior to planting, it is important to prepare the soil by removing any weeds, tilling, and adding organic matter such as compost or well-rotted manure to improve drainage and fertility.
3. Asparagus plants should be spaced about 18 to 24 inches apart in trenches that are 6 to 8 inches deep. The crowns should be placed at the bottom of the trench with the bud points facing upward.
4. After planting, it is crucial to keep the soil consistently moist but not waterlogged. Regular irrigation is necessary during dry periods to ensure healthy growth and development.
5. Harvesting of asparagus can typically begin 2 to 3 years after planting, allowing the plants to establish a strong root system. During the harvesting season, only spear thicknesses of at least 3/8 inch and heights of 6 to 8 inches should be harvested to avoid weakening the plants.
When is the Best Time to Plant Asparagus in Missouri?
1. Understanding the Growing Season for Asparagus
Asparagus is a perennial vegetable that requires proper planning and timing for successful growth. Before deciding when to plant asparagus in Missouri, it is essential to understand the growing season of this delicious vegetable. Asparagus is a cool-season crop that thrives in moderate temperatures, typically between 50 to 75 degrees Fahrenheit.
2. Considering Missouri’s Climate
Missouri experiences a variety of climates, from the hot and humid summers to cold winters. It is crucial to take these weather conditions into account when determining the ideal time for planting asparagus. Asparagus plants prefer cooler temperatures during the growing season and need a dormant period during winter for optimal growth.
3. Early Spring Planting
One of the best times to plant asparagus in Missouri is during early spring, typically around March or early April. The soil should be workable and have warmed up to around 50 degrees Fahrenheit. Planting during this time allows the asparagus crowns (root systems) to establish themselves before the onset of summer’s heat.
4. Soil Preparation
Asparagus thrives in well-draining soil with a pH between 6.0 and 7.0. Before planting, it is crucial to prepare the soil properly. Remove any weeds, rocks, or other debris from the planting area. Add organic matter, such as compost or well-rotted manure, to improve soil fertility and drainage. It is also recommended to perform a soil test to assess nutrient levels and make necessary amendments.
5. Selecting and Planting Crowns
Asparagus is typically grown from crowns, which are one-year-old dormant plants. Select healthy and disease-free crowns from a reputable nursery or supplier. Dig trenches that are approximately 8 to 12 inches deep and 12 to 18 inches wide. Place the crowns in the trench, spacing them around 12 to 18 inches apart. Cover the crowns with 2 to 3 inches of soil initially, gradually filling the trench as the plants grow.
6. Caring for Asparagus Plants
Once the asparagus plants are established, proper care is vital for their growth and productivity. Keep the plants well-watered, providing around 1 to 1.5 inches of water per week. Mulch can be applied to the soil’s surface to help retain moisture and suppress weed growth. Regularly remove any weeds that may compete with the asparagus for nutrients and water.
7. Harvesting Asparagus
While it may be tempting to harvest asparagus soon after planting, it is essential to exercise patience. Asparagus should not be harvested during the first year to allow the plants to establish a strong root system. In subsequent years, you can begin harvesting spears when they reach a height of 6 to 8 inches. Cut the spears at ground level and avoid damaging surrounding shoots.
8. Protecting Asparagus through Winter
As the growing season ends and winter approaches, it is essential to protect your asparagus plants from freezing temperatures. After the first frost, cut down the fern-like foliage to about 2 inches above the ground. Apply a layer of mulch around the plants to insulate the crowns and prevent heaving during freezing and thawing cycles.

FAQ
1. When is the best time to plant asparagus in Missouri?
The ideal time to plant asparagus in Missouri is in early spring, once the soil has thawed and reached a temperature of around 50°F (10°C). This typically occurs between late March and early May.
2. Can asparagus be planted in the fall?
While fall planting is possible for asparagus in some regions, it is generally not recommended in Missouri. Asparagus plants require a period of dormancy during winter, and planting in fall may not allow them enough time to establish a strong root system before the cold weather sets in.
3. What type of soil does asparagus prefer?
Asparagus thrives in well-drained soil with a pH level between 6.5 and 7.5. It prefers sandy or loamy soil that is rich in organic matter. Sandy soil provides good drainage, which helps prevent root rot.
4. How deep should I plant asparagus crowns?
When planting asparagus crowns in Missouri, dig a trench that is about 8-10 inches deep. Place the crowns at the bottom of the trench, spreading out the roots, and cover them with 2-3 inches of soil. Gradually fill in the trench as the plants grow throughout the season.
5. How far apart should I space the asparagus plants?
Space each asparagus plant about 12-18 inches apart within the row. Leave 3-5 feet between the rows to allow sufficient space for the plants to spread out as they grow.
6. Can asparagus be grown in containers?
While it is possible to grow asparagus in containers, it is not ideal. Asparagus plants have deep and extensive root systems, which may be restricted in containers, leading to stunted growth. They also require a lot of space to support multiple plants. If growing in containers, choose a large and deep container to accommodate the roots.
7. How long does it take for asparagus to start producing edible spears after planting?
After planting asparagus crowns, it typically takes about 2-3 years for the plants to reach maturity and start producing edible spears. However, the wait is worth it, as asparagus plants can continue to produce for up to 15 years with proper care.
8. Should I trim the asparagus ferns after they turn yellow in the fall?
It is important to leave the asparagus ferns intact after they turn yellow in the fall. The ferns are responsible for transferring energy to the roots, which strengthens the crowns and prepares the plants for the following season. Trimming them too early may weaken the plants and reduce future harvests.
9. How often should I water my asparagus plants?
Asparagus plants require regular watering, especially during dry spells or droughts. Provide around 1-1.5 inches of water per week, either through rainfall or irrigation. Water deeply and infrequently rather than daily shallow watering to encourage strong root growth.
