What are the planting methods and precautions for Asparagus cochinchinensis?

When it comes to Asparagus cochinchinensis, everyone is surely very familiar with it; it is especially common in our daily lives. Asparagus cochinchinensis may look unremarkable, but its effects and functions are considerable, it has extremely high medicinal value, has good curative effects on treating certain ailments, and is widely cultivated. So how exactly should Asparagus cochinchinensis be grown? Let us discuss the cultivation techniques for Asparagus cochinchinensis below!

How to grow Asparagus cochinchinensis

1. Choose soil with good drainage and relatively good aeration, level it before sowing, remove large stones, weeds and other impurities, and carry out sterilization treatment.

2. Make horizontal trenches about 7 cm deep at a spacing of about 22 cm, then sow, with the seeds at a depth of 6 cm, and adjacent seed holes about 2 to 3 cm apart. If you are unsure of the seed quantity, you can consider it based on a rate of 20 jin per mu.

3. After the seeds are planted, spray water, cover with base fertilizer or plant ash, then cover with finer soil until it is level with the trench surface, and finally cover with straw mats to reduce loss of moisture and temperature.

4. Keep the temperature at around 18 degrees, watch the dry and wet condition of the soil, and replenish water in time. After about 20 days the seeds will sprout into small seedlings; once the seedlings are visible to the naked eye, remove the straw mats on top and carry out later-stage management.

Planting methods and precautions for Asparagus cochinchinensis

1. Soil requirements

It likes a warm and humid environment, likes sunlight, tolerates partial shade, and fears direct strong light. A loose, fertile, well-drained sandy loam is suitable. When cultivating Asparagus cochinchinensis in the north, repotting is mostly carried out in mid-to-late April. During repotting, cut off some old roots and add a culture soil mixed evenly from 4 parts leaf mold, 4 parts garden soil, and 2 parts river sand.

2. Watering method

In spring, water thoroughly once every 2 to 3 days. At this time, if the air is dry, spray water on the plants every day and sprinkle water on the ground around the maintenance area facing the sun; in summer, spray water every day and water once every 2 to 3 days to increase air humidity. Asparagus cochinchinensis has fleshy roots and fears waterlogging, so it should not be watered too much normally; in summer, water thoroughly once a day.

3. Fertilization method

From May to September is its vigorous growth period, and it can be given a decomposed cake fertilizer solution once every 15 to 20 days. If indoor light is insufficient, it is advisable to place it outdoors for maintenance for a period of time in spring and autumn; in winter, place it in a place with sufficient indoor light, keep the room temperature above 5 degrees C, water once every 10 to 15 days, and spray and wash the branches and leaves once every 3 to 5 days.

4. Propagation method

Asparagus cochinchinensis is mostly propagated by division, which can be done together with repotting in spring. The mother plant should be a plant more than 3 years old. When dividing, take the mother plant out of the pot and, according to the size of the clump, divide and plant it into several pots, water thoroughly, and place it in semi-shade for 10—15 days. The seeds mature at the end of December; after harvesting, soak them in water, rub off the fruit skin, and dry them in the sun. Sow in spring; the indoor temperature should not be lower than 15 degrees C, and they will germinate in about one month. When the seedlings are about 4—5 cm long, divide and plant them, with several plants per pot.

What to do if the stems and leaves of Asparagus cochinchinensis turn yellow

1. Lack of nutrients

The phenomenon of yellowing leaves in Asparagus cochinchinensis may be caused by a lack of nutrients. When Asparagus cochinchinensis is grown in one pot, after it grows and develops the tuberous roots in the pot become numerous and tangled together, which leads to insufficient nutrients in the pot. At this time we need to divide or repot it. After dividing or repotting Asparagus cochinchinensis, appropriately apply some diluted fertilizer, and the leaves will gradually turn green again.

2. Improper fertilization

During the growth period of Asparagus cochinchinensis, if some undecomposed organic fertilizer is applied, it can easily cause root burn, which will lead to a large number of yellow leaves and dead branches in Asparagus cochinchinensis. Therefore, when fertilizing Asparagus cochinchinensis, be sure to apply decomposed liquid fertilizer, applying a small amount each time and applying it more times, so as to ensure sufficient fertilizer and good absorption for Asparagus cochinchinensis.

3. Excessive light

If young Asparagus cochinchinensis plants are placed directly under strong sunlight, it is very easy to cause the stems and leaves of Asparagus cochinchinensis to turn yellow. When growing Asparagus cochinchinensis, we must pay attention not to let strong sunlight shine on the plants. In summer, set up a shade structure to prevent sun exposure. Asparagus cochinchinensis is more suitable for growing in semi-shade.

Pest control for Asparagus cochinchinensis

1. Red spider mite

Red spider mites damage the leaves from May to June. Control methods: (1) In winter, pay attention to cleaning the garden and bury deeply or burn the dead branches and fallen leaves; (2) Spray 0.2-0.3 degree Baume lime sulfur mixture or use 25% chlordimeform aqueous solution diluted 500-1000 times for spraying, once a week for 2-3 consecutive times.

2. Aphids

Aphids harm the young vines and bud cores, causing the entire vine to wither. In the early stage of aphid damage, you can use 40% dimethoate diluted 1000-1500 times or mieyaling diluted 1000-1500 times for spraying and killing. For plants with severe pest damage, you can cut off all their vines and apply fertilizer, and in about 20 days new buds and vines will sprout.

Through the above content, I believe everyone has gained a certain understanding of the cultivation techniques for Asparagus cochinchinensis. In fact, Asparagus cochinchinensis also has high ornamental value, and many people like to grow potted Asparagus cochinchinensis at home to decorate their rooms!
