Asparagus growing techniques help bring high yields

Asparagus growing techniques help bring high yields

1. When should you start growing asparagus?

The best time to plant asparagus is early spring. Some varieties can be grown from sprouts while others can be grown from seeds. Start the seeds indoors in the spring and grow the seedlings when they are 12 to 14 weeks old, before planting them in the ground.

  • Soak seeds in water for up to 24 hours before sowing.
  • Sow the seeds in moistened peat or nursery soil in a blister
  • When the plants reach 12 inches in height, put the hardy seedlings outdoors for a week.
  • Then, transplant the young plant into a temporary bed in the garden.As they mature in the fall, identify berry-poor male asparagus plants and transplant them into your permanent planting site, discarding less productive female plants.
  • Remember to keep space between the asparagus because they will grow even stronger in the following years.

2. Select and prepare a suitable location for planting asparagus

Choose an asparagus bed location toward the edge of your garden, where it won't be disturbed by other growing activity.

Choose an asparagus bed location toward the edge of your garden

Because asparagus is a perennial plant that grows back every year in the same location, it is important to choose the right planting location for the plant to thrive. Forasparagus growing techniques,you need to note:

  • Prioritize an area with direct sunlight for at least a few hours a day.
  • Choose an asparagus bed location toward the edge of your garden, where it won’t be disturbed by other growing activity.
  • Make sure the planting bed has good drainage and no standing water. Asparagus does not like having the lower stem “wet”. If you don’t have a location with good drainage available, consider growing asparagus in a raised bed.
  • Asparagus thrives in acidic to slightly acidic soil (pH around 6.5).
  • Remove all weeds from the planting area, dig up the soil and mix it with compost, manure or suitable biological soil treatment products.
  • Clean the weeds, dig the soil to a depth of 12 inches, mix well with compost, decomposed manure or biological soil treatment products to increase porosity and nutrients.
  • When preparing soil, farmers should dry the soil for at least 7–10 days before planting to kill pathogens and harmful nematodes. Adding lime powder also helps disinfect the soil and stabilize the pH more effectively.

3. Technical instructions for growing asparagus

  • Dig a trench about 12 to 18 inches wide and 6 to 8 inches deep. If digging multiple trenches, space the trenches at least 3 feet apart.
  • Soak the stem in warm water before planting.
  • Make a mound 2 inches high along the center of the trench. After that, plant the young tree in the trench
  • In the trench, space the asparagus spears 12 to 18 inches apart (from root tip to root tip).

You can then proceed with the following two methods:

Method 1:

  • Cover the bamboo shoots with compost and topsoil and bury the stems 2 inches deep. Then water
  • When the plant begins to grow and is 2 to 3 inches tall, add another 2 inches of soil into the trench,Avoid burying the entire body.
  • When the asparagus tips grow through the soil again, add a 2-inch layer of soil. Do this process until the trench has been filled to ground level. Depending on how deep you dig your trench, you may need to add soil 1 to 2 more times throughout the season.
  • Once you’ve completely filled the trench, mound it a bit to prevent water from pooling around the emerging shoots.

Method 2:

Some people simply fill the trench with soil and compost at the same time. Although it is believed that the traditional method does not affect the growth of the plant.  As long as the soil is fairly loose, the shoots will have no problem pushing to the surface.

During the planting process, farmers can add a small amount of decomposed organic fertilizer or Trichoderma product to the trench to help the soil rich in beneficial microorganisms. This increases the roots’ disease resistance and promotes strong plant growth right from the early stages. At the same time, a layer of dry straw or rice husk should be placed on the ground after planting to retain moisture and limit grass growth.

The soil should be loosened to a depth of 12 to 15 inches to allow the asparagus stems to root properly.

4. Instructions on how to care for asparagus plants

Once the trench is filled, you should add a layer of mulch 4 to 6 inches high. The biggest problem with asparagus is dealing with weeds in the first two years. The roots of asparagus should not be disturbed so you need to pull the weeds by hand gently, being careful not to disturb the roots. Weeds will become less of a problem as the plant matures and becomes established. Mulch around the plants with compost or grass clippings to help keep the soil moist and reduce weed growth.

During the first 2 years after planting, asparagus plants need to be watered in an appropriate amount. If the plant is not receiving enough rain, you will need to water it additionally. Use drip irrigation if possible. Asparagus thrives on a steady and consistent supply of nutrients. Therefore, you need to consider applying organic fertilizer during the growth period of the asparagus plant.

To fertilize asparagus, it is necessary to fertilize with well-rotted organic fertilizer before planting. After planting, fertilize periodically every 15-30 days with NPK fertilizer combined with organic or microbial fertilizer, paying special attention to applying additional fertilizer after each harvest and when the tree begins to produce the first batch of bamboo shoots. Stop fertilizing about 15 days before harvesting the next batch of bamboo shoots.

Use of productsbiological fertilizer, vermicompostAlso highly recommended. Additionally, you should also supplement with probiotic-containing productstrichoderma fungusResist fungal diseases, treat nematodes. They will act as a solid protective layer to prevent the attack of harmful pathogens. At the same time, it helps bamboo shoots grow well and increase productivity. Especially the use of microbial fertilizers as well as biological products is both safe. Additionally, there can be significant savings in annual fertilizer costs for plants.

In addition, it is necessary to regularly prune old leaves and dry stems to help keep the garden airy, limit pests and diseases, and help nutrients concentrate on feeding young stems. If leaves are found to show signs of yellowing or brown spots, you should check for nematodes or fungal diseases under the roots for timely treatment.

5. Notes when harvesting asparagus

Do not harvest asparagus during the first year (plants need time to develop their roots). Cut back dead foliage in late fall and fertilize with compost and biofertilizer. In the second year, harvest for only 3 to 4 weeks, fertilize with compost in spring and early fall and cut off dead branches in late fall. Keep the bed thickly mulched.

In the third year, according to asparagus growing techniques, more young plants will be born. So you can start harvesting asparagus throughout the season. At this time, check the tree every day to find bamboo shoots ready to harvest. Asparagus grows quickly and can become too tough before you know it. Once the asparagus spears begin to open and develop foliage,you should not harvest them. 

The most ideal bamboo shoots are themreach height8 to 10 inches and ½ to ¾ inch thick. (Remember that younger and thinner bamboo shoots are more tender, so harvest according to your own standards.)

To harvest asparagus, simply cut the spears with a knife or sharp scissors close to the ground. Stop harvesting spears when the diameter of young asparagus reduces to the size of a pencil. After harvesting, fertilize your asparagus in early summer. You can apply a layer of balanced organic fertilizer so that the plant has all the nutrients it needs to grow.

After each harvest, you should clean the garden thoroughly, removing grass, old roots and dry leaves. This helps prevent fungal diseases from recurring and maintains soil porosity. With good care conditions, an asparagus root can produce a stable harvest for 8–10 years, bringing long-term profits.
