Asparagus is a green vegetable that grows in winter. We usually can find it in the supermarket.
Asparagus fried is very delicious and popular among people. Nowaday more and more gardeners are starting to plant asparagus in the garden.
We highly recommend you to read “What are the benefits of asparagus“
Asparagus also grows in the mountains or in the wild. Sometimes you can occasionally see some wild asparagus outdoors. Asparagus grows out, it means spring is here.
So how should asparagus in the garden be grown? This article explains how to grow asparagus!
- First observe whether asparagus can be planted and grown well in your garden. If the soil can directly freeze and solidify in winter, it means that it cannot be planted.
Although asparagus is hardy by nature, it can be troublesome to grow in a place that is very humid in summer and mild in winter.
- Asparagus can be planted from seed or corolla. Asparagus planting needs to grow for three years before fruiting.
Therefore, asparagus is a kind of plant with very long growth cycle. It will take two years to grow after germination before the root can be planted in the soil.
If you start planting from the corolla, you can go directly to the rooting step, and plant it two years in advance.
- The germination rate of asparagus seeds is not high, so it is difficult for us to estimate the survival rate and harvest rate at the beginning.
However, the survival time of asparagus seeds is longer than that of adult asparagus, and it can grow more tender stems, so that it can grow better asparagus.
- Choosing a planting location, we have to choose a place that can grow asparagus for a long time.
Because asparagus can grow fresh and tender stems continuously for 25 years, the planting area must be able to exist for a long time, so as to ensure its growth time, and the growing area must have sufficient light to make it grow better.
- After sowing, wait until the seedlings have grown. When the seedlings grow to 30 cm high, they can be planted on the seedling bed, and then a 7.5 cm hole is dug, which is more conducive to their development.
- The seedbed should be prepared when transplanted to the seedbed. The first step is to weed the seedbed to ensure that there are no residual roots before fertilizing;
Then dig trenches to a depth of about 30 cm. If there are many rows of plants, the spacing will be doubled or more.
- Plant the corolla in the trench, cover the corolla and roots with soil, water the soil after planting, and then fill it back with soil.
When the asparagus begins to grow, add soil to the corolla for two or three weeks until the soil is as high as the trench.
- The last thing is to prevent pests and diseases. Asparagus is easily affected by some beetles.
Asparagus beetles mainly gnaw on the tender stems of ferns and lay their eggs on them. Once they are found, measures must be taken to drive them away or eliminate them.
Asparagus sprouts new stems 2-3 times a year or more. The tender stems that sprouted in spring are generally used for food, and their growth depends on the supply of nutrients stored in the roots the previous year.
The growth of tender stems and the formation of yield are positively related to the number of stems formed in the previous year and the degree of luxuriant branches and leaves.
As the plant ages, the number of tender stems and yield increases year by year.
As the rhizomes continue to branch out, the growth of the plant clusters tends to decline, the above-ground stems are getting smaller, and the yield and quality of tender stems are gradually decreasing. Generally, 4-10 years after planting is the abundant production period.
If you want to grow asparagus in the open air, grow seedlings in April and May, and plant them in July and August.
If you grow asparagus in a greenhouse, you can also grow seedlings in August and September, and plant them in October.
