Before telling how to growing asparagus in pots, first, tell the gardeners some basic knowledge that must be understood;
Then the gardeners decide whether to continue potting asparagus. Generally speaking, we can plant asparagus in a pot or plant the rhizome directly;
If it is planting, it will take at least 3 years to pick a small number of bamboo shoots, and 5 years later is the peak harvest period. Of course, if you buy rhizome seedlings directly for planting, you can shorten this time.
In addition, gardeners who plant asparagus in pots need to prepare deeper flower pots. Generally, shallow pots are not suitable for growing asparagus.
According to the requirements for planting asparagus, if gardeners want to pot asparagus, they must first have 3-5 years to expect, and there is also a larger and deeper pot preparation.
The method of growing asparagus in pots
Asparagus is highly adaptable, easy to cultivate, and does not require strict temperature requirements. The underground part can withstand low temperatures of -4°F in the soil in winter and can withstand high temperatures of 95-100°F during the growing period.
It grows throughout the year in the colder season. In some areas, it enters a dormant state in winter and will continue to grow in the second year.
Seed Treatment
Before sowing, soak in warm water at 75°F-85°F for 3-5 days, change the water 1-2 times a day, wait until the seeds absorb enough water to remove them, mix with fine sand or vermiculite, put them in a container, and cover with a wet towel. Place the germination at 75°F-85°F, turn it twice a day, and sow after 5-8 days of whitening.
For sowing, you can use peat soil or nursery soil plus nursery tray, nursery block and nursery box to grow seedlings. The thickness of the soil is about 2-3 cm, and the temperature is 75°F-85°F.
Choose the right flower pot
Planting asparagus requires the preparation of suitable flower pots and soil, usually a clay pot or ceramic pot with good air permeability;
Then fill the pot with the mixed soil of leaf mulch and river sand prepared in equal proportions, leaving a certain space to avoid being too full, and adding the appropriate amount of organic fertilizer to the soil to make it more fertile.
When planting asparagus, you must apply foot base fertilizer. You can use decomposed organic fertilizer as the base fertilizer for planting asparagus.
For family balcony potted planting, you must choose a deeper pot, preferably more than 50-60 cm deep.
Seedling colonization
When asparagus seedlings are more than 15 cm high, they can be moved into flower pots. The depth of the pot should be more than 25 cm. The organic-rich sandy loam with a pH value of 5.8-7 or the sun-dried broken pond mud can be used for sand washing (3:1) After being exposed to the sun for 1 week and disinfected, it is used as potting soil, and then decomposed manure and compound fertilizer are used as base fertilizer.
Daily management
After planting, pay attention to ventilating and moisturizing. Soil moisture is maintained at 60%-70%. Water should be properly watered during drought. Drainage ditch should be dug in rainy season to prevent water from rotted roots.
Harvest
The asparagus begins to germinate in the second year of planting, but do not harvest the asparagus first. You have to wait until the 5 branches have grown before picking the asparagus. This will lay a good foundation for high yield in the future. The third year enters the high-yield period. At this time, only three branches are left for harvest. The high-yield period can be as long as 8-13 years.

Precautions
Asparagus grows fast and requires high water and fertilizer management. Fertilizer is applied 3 times a year. Asparagus should not be picked in the first year after the asparagus family potted culture is planted. In colder areas, the plant will enter the dormant period and stop growing. It is recommended to place the plant 15 cm away from the root. Cut off the left and right parts and hibernate the asparagus.
