Asparagus, a delicious and nutritious vegetable, is a perennial plant that takes some patience to grow. While it is possible to start asparagus from seed, it typically takes three years for the plants to mature and start producing edible spears. To avoid this long wait, many gardeners prefer to grow asparagus from 1-year-old crowns, which are the root systems of mature plants.
Planting asparagus crowns is a popular choice because it allows you to enjoy a harvest sooner. The crowns are typically planted in late winter or early spring, as soon as the soil is workable. This timing is crucial as it gives the plants ample time to establish themselves before the growing season begins.
When planting asparagus crowns, it is important to prepare the soil properly. Asparagus thrives in well-draining soil enriched with organic matter. Before planting, remove any weeds or grass from the area and loosen the soil to a depth of around 12 inches. Incorporate compost or well-rotted manure to improve the soil’s fertility.
Next, dig trenches that are about 6-8 inches deep and 12-18 inches wide. Space the trenches about 3-4 feet apart to allow enough room for the asparagus plants to spread out. Place the crowns in the trenches, spacing them about 18 inches apart. Cover the crowns with a few inches of soil, leaving the tips exposed.
As the asparagus plants grow, gradually fill in the trenches with soil until they are level with the ground. This process, called “hilling,” helps to promote strong and healthy root development. Additionally, it prevents the crowns from being exposed to frost or sunlight, which can damage them.
During the first year of growth, it is essential to provide proper care to ensure the long-term success of your asparagus bed. Water the plants regularly, especially during dry spells, to keep the soil consistently moist. Apply a layer of mulch around the plants to help retain moisture and suppress weed growth.
To encourage the development of a strong root system, it is recommended to avoid harvesting any spears during the first year. By allowing the plants to focus their energy on root growth rather than producing edible spears, you can ensure a healthier and more productive crop in the future.
In the second year, you can begin harvesting asparagus spears for a short period, typically about 2-3 weeks. However, it is important to stop harvesting once the spears become thin and spindly, as this indicates that the plants need to replenish their energy reserves.
By the third year, your asparagus plants should be well-established and ready for a full harvest. During this time, you can enjoy a longer harvest period, generally lasting 6-8 weeks. Asparagus plants can continue to produce for 10 years or more, so the initial wait is definitely worth it!
In my own experience, I started growing asparagus from crowns a few years ago. Although it was difficult to resist the temptation to harvest any spears during the first year, I followed the advice of experienced gardeners and allowed the plants to focus on root development. The following year, I was rewarded with a small but delicious harvest. Now, in the third year, my asparagus bed is thriving, and I can enjoy a bountiful harvest for several weeks.
While asparagus does not come up the first year you plant it, it is well worth the wait. By starting from crowns instead of seeds, you can expedite the process and begin harvesting edible spears within a few years. With proper care and patience, your asparagus plants can provide a delicious and nutritious harvest for many years to come.
