“Asparagus” comes in a variety of colors and shows off, such as green, white, and more recently purple. When first planted, it takes about two years to harvest, but after that, you can harvest for many years with one variety. So this time I will explain the points for growing asparagus well.
Basic knowledge of asparagus
What kind of vegetables are asparagus?
Asparagus has the Japanese name “Dutch Kijikakushi”. At first glance, asparagus has a unique shape, but in fact, what we eat for food is the young body of asparagus. The triangular thing called “Hakama” on the stem is the leaf, and what looks like a leaf is called “fake leaf (temporary leaf)”, which corresponds to the divided branches.
There are several types of asparagus on the market, apart from the familiar “green asparagus”, “white asparagus” in canned foods, “purple asparagus” contains anthocyanins and is purely purple in color, with thin stems. There are “mini asparagus” harvested assorted asparagus when it is still small.
Asparagus grows naturally from southern Europe to southern Russia and is grown mainly in cool regions. Hokkaido is the main production area in Japan. As a vegetable containing abundant protein, green asparagus also contains nutrients such as vitamins A, B1, B2, C, E and folic acid, in addition to being rich in aspartic acid, which is an amino acid. . Asparaginic acid is believed to be effective in reducing fatigue and fatigue, and asparagus, which goes well with any dish like tempura, salads, and fried foods, is one of the vegetables you definitely want to eat. hot season.
Characteristics of asparagus seedling
Asparagus can be grown by sowing seeds, but usually you have to buy commercial seedlings and start planting. If you buy the seedlings that are first planted are called “small seedlings”, harvesting will begin in the third year. On the other hand, if you buy a “large seedling” that has been planted for several years, you can harvest it from that year.
Time to grow asparagus
Asparagus is sown from March to April to produce seedlings, harvested from late April to early June. The harvest season is around September to October. Asparagus seedlings can yield from one tree to 10 years, so when growing in the field, consider where to plant.
Plant cultivation methods in the factory
Asparagus can also be grown on your patio with a large planting pot. The points for planting are as follows.
For an asparagus growing truss, prepare a deep hole 20 cm or more in depth (number 10 or more). Plant only one plant per pot.
Commercially available land for vegetable cultivation can be used with a suitable acidity of pH 6.0-7.0. Before adding soil, place a light stone that will be the bottom rock in the potted plant. Add about 3-4 cm of soil and water well until water comes out from the bottom of the pot. After draining, add more concentrated chemical fertilizers and cover the soil about 5 cm. After planting seedlings, sprinkle 4-5 cm of soil over the buds, and finally water them soaked.
After planting, keep in a place as sunny as possible, watering the plants daily. Asparagus is a fertilizer-loving plant, so sprinkle chemical fertilizers along the edges of your growing truss or apply liquid fertilizer every two weeks. When they get tall, they stand up to prevent them from falling, and weeds are carefully handled to prevent nutritional deficiencies.
It is time to harvest asparagus as it grows to a height of about 20 to 25 cm. According to the thickness guide, it should be as thick as your index finger.
Divide asparagus warehouse
You can enjoy the asparagus harvest for about 10 years with one line, but since the root growth momentum is strong, we will divide the plots before causing root clogging. The best time to split stock is from May to June, although avoid the harvest season, mid-summer and mid-winter. For seeds that have been removed from the planting platform, remove about 1/3 of the old soil, remove the old roots and replant them in a larger bin. According to the instructions, the amount divided from one share is about 2-3. After separating the herd, administer in the shade for a while, then return to normal management while acclimating to sunlight.
Precautions for asparagus farming methods
The green asparagus and the white asparagus are identical. Only color will be different depending on how you plant it. Green asparagus is grown in sunlight. On the other hand, white asparagus is grown according to the “soft white farming” method that blocks sunlight. This is a farming method that grows white without forming chlorophyll by planting it by creating a shade or covering the soil. If you do this in a potted plant, you can simply cover it with a shade to block out sunlight once it has sprouted. Purple asparagus is a variety with a bright purple color, but there are no differences in cultivation methods. Also, when boiled, it turns green.
When you want to grow in this field
When farming in the field, how to freeze it is important. Asparagus becomes active in foliage development when young stems are harvested. It opens the leaves for photosynthesis, stores nutrients in the roots in preparation for hibernation, and enters the deepest hibernation period as the leaves fade. At this time of year use the sickle to cut 5 to 7 cm from the ground and dry in place for treatment. This is the way to protect asparagus from pathogens. Then, deep trenches are dug on both sides, and compost and hay with moderate fermentation are applied to the trench, and the soil is raised in the trench to fill the base of the asparagus, and the base is cooled. . Prevent from. Then, around March, the soil is removed to a degree that does not interfere with germination, and the soil is released into the trench by “returning the soil”, and fertilizing with chemical fertilizers and organic compost.
