How to grow asparagus and point

Asparagus eat young shoots

Asparagus is a vegetable that eats young shoots (actually stalks). Wakaguki is harvested in spring when it germinates on the earth’s surface.
The difference between green asparagus and white asparagus is the farming method. It becomes white asparagus by filling it and blocking light. In recent years, there is also purple variety.
They like cool climates, and in Japan they are mainly produced in the provinces of Hokkaido and Nagano, but they can also be grown indoors in Shikoku and Kyushu. Harvest times vary depending on farming methods such as field cultivation and indoor farming, but are generally harvested from spring to summer.

Nursery seedling

It can be said that asparagus root is a storage place for nutrients, and grows using the nutrients stored in the roots. The greater the deformation, the higher the productivity.
After sowing, these strains need to be planted for a year or two so that they can store enough nutrients, during which time they cannot be harvested.
Asparagus is a perennial plant that can be planted every year, only once every 10 years or so. You can grow it from seeds, but if you buy cell seedlings

And plant them, you can harvest them as early as next spring. Considering the time and effort required and harvest time, it can be easier to buy and plant seedlings when growing asparagus in your home garden.

* Seedlings are grown in split boxes (umbrella tray).

Asparagus likes a sunny place.
From spring to summer, it is exposed to sunlight to store nutrients. We harvest young stalks about 25 cm long, but leave about 5 to 6 stems as strong as they were originally. The remaining stems (called the parent and trained stalk) are planted for photosynthesis. This is called a vertical stem, and when the leaves are thick and photosynthesis occurs, the nutrients of the roots used for the shoot are stored. You can harvest it when the sapling is different from the stem of the mother plant.
The mother stalk dies yellow in winter. When it turns yellow, the exposed part of the ground is cut from the base and burned for processing.

Then, using the nutrients stored in the roots that remain in the soil, they will sprout when spring comes.

The body is tall and has deep roots
Asparagus usually grows to 2 meters or more in length. Some of them are out of the reach of the top. Use a support and a net to stabilize the stem so that it won’t fall over.
In addition, the roots reach a depth of 1 meter or more and a width of 1.5 meters or more.
Since plants are susceptible to moisture and dryness, it is also important to pre-plant them in well-drained soil, make more soil with compost, etc., and water a lot.

Also, apply liquid fertilizers when watering.

Asparagus disease
Asparagus suffers from a deadly disease called blight.
As brown spots appear on stems and get heavier, the entire foliage will die.
Regularly take measures such as using chemicals and removing the diseased stem, and at the same time taking measures such as rain shading, mud splashing.

In winter, the cold can cause frost damage. Prevent frost damage by covering the ground with compost or mulch.

How to grow asparagus in the growing truss?
As mentioned above, asparagus is very deep. Therefore, to plant it in the growing truss needs to be small or deep. Also, since it can be harvested for a long time, a durable one should be chosen.

To improve drainage, people spread shiny red soil at the bottom of the planting pot, and cultivated soil is poured over it and planted.

Growing hydroponic asparagus
Is it possible to grow hydroponic asparagus?
The hydroponic growing method uses water and liquid fertilizers without the use of land, does not require large fields and can be easily tried indoors.
It is also possible to grow asparagus using the hydroponic method. However, in terms of foliage taller than adults and root system deeper and wider, it can be said that growing hydroponic asparagus at home is not very suitable.
It is also a perennial plant, can be harvested for more than 10 years, and water management in that time can be imagined as difficult.

According to Mr. Satoru Motoki, associate professor in the Department of Agriculture, Faculty of Agriculture, Meiji University, who is familiar with asparagus cultivation underwater, said: “Underwater asparagus planting can be experimental, but economically (income). For crop purposes) it is strictly rarely done. We are also conducting research with companies for real-world use. “

In order to grow delicious asparagus, it is important to store nutrients in the roots. Why don’t you like to prepare delicious asparagus by preparing an environment so that the roots can be restored?
