How to grow asparagus

I. planting preparation

1. First of all, observe whether asparagus can grow in the place where it is planted. If the local soil can be directly frozen in winter, it means it is not suitable to grow. Although asparagus is hardy by nature, it is troublesome to grow asparagus if it is very humid in summer and mild in winter.

2. Asparagus can be planted by planting seeds or Corolla. Asparagus needs to grow for three years before bearing fruit, so asparagus is a kind of plant with a very long growth cycle, which takes two years after germination before it can be rooted in the soil. If it can be planted directly from Corolla to rooting, it can be planted two years in advance.

3. The seed germination rate of asparagus is not high, so it is difficult to estimate the survival rate and harvest rate at the beginning, but the seeds can survive longer than the Corolla and grow more tender stems.

4. to choose the planting site, we should choose a place where asparagus can grow for a long time, because asparagus can grow tender stems for 25 years, so the planting land should be able to exist for a long time, so as to ensure its growth time and enough light to grow in order to make it grow better.

II. Seed planting

1. After sowing, wait until the seedlings grow out, and when the seedlings grow to a height of 30 cm, they can be planted on the seedbed, and then dig a hole in 7.5cm, which is more conducive to their development.

2. It is necessary to prepare the seedbed when it is transplanted to the seedling bed. The first thing is to weed the seedbed to ensure that there are no residual roots before fertilizing, and then dig trenches with a depth of about 30 centimeters. If you plant a large number of rows, the spacing should be doubled or more.

3. Plant the Corolla into the trench, cover the Corolla and roots with soil, water the soil after planting, and then fill the soil back. when the asparagus begins to grow, add soil to the Corolla for two or three weeks until it is as high as the trench.

4. Finally, it is the prevention and control of diseases and insect pests. Asparagus is easily affected by some beetles. Asparagus beetles mainly bite on the tender stems of ferns and lay eggs on them. Once found, measures should be taken to drive them away or destroy them.
