How to Grow Asparagus? Planting Methods and Key Field Management Points

I. Planting Preparation

1. First observe whether asparagus can grow in the planting site. If the local soil freezes solid in winter, it is not suitable for planting. Although asparagus is cold-hardy by nature, it is very troublesome to grow in places that are very humid in summer and relatively mild in winter.

2. Asparagus can be grown from seed or from crowns. Asparagus takes three years to bear before it produces results, so asparagus is a plant with a very long growth cycle. After germination, it still needs to grow for two years before the roots can penetrate into the soil. If grown from crowns, you can go directly to the rooting stage, planting two years earlier.

3. The germination rate of asparagus seeds is not high, so it is very difficult at the beginning to estimate the survival rate and harvest rate. However, plants grown from seed can survive longer than those grown from crowns and can produce more tender spears.

4. Choose the planting site. We need to choose a place where asparagus can be grown for a long time, because asparagus can continuously produce tender spears for twenty-five years, so the planting site must be able to remain in place for the long term. This is the only way to guarantee its growing time. The growing site must have sufficient sunlight so that it can grow better.

II. Growing from Seed

1. After sowing, wait until seedlings emerge. Once the seedlings have grown to 30 cm tall, they can be planted out into the seedbed. Then dig a 7.5 cm hole, which is more conducive to their development.

2. When transplanting to the seedbed, you need to prepare the seedbed first. First, weed the seedbed and make sure there are no residual roots, then apply fertilizer, then dig trenches about 30 cm deep. If many rows are being planted, the spacing should be extended to double or more.

3. Plant the crowns into the trenches and cover the crowns and roots with soil. After planting, water the soil, then fill the soil back in. When the asparagus begins to grow, add soil over the crowns, continuing for two to three weeks, until the soil has been added up to the same height as the trench.

4. Finally, there is pest and disease control. Asparagus is easily affected by certain beetles. Asparagus beetles mainly bite the tender spears of fern-like plants and lay eggs on them. Once discovered, measures must be taken to drive them away or eliminate them.
