WAYS OF GROWING ASPARAGUS

This plant likes to grow in cold areas. The young stem shoot of the plant is edible and it emerges when the temperature of the soil is above 50 degrees Fahrenheit in the spring. 

There are two ways of growing asparagus, the first is from one-year-old plants or crowns and the second is from the seeds. If you grow asparagus plants from the crowns then it can eliminate the time of tedious weedings. 

If you are growing asparagus for the first time then you should grow 10 to 20 asparagus plants in a row of 15 to 30 feet. 

Now we will discuss both methods one by one so you will understand both ways of planting asparagus.

GROWING ASPARAGUS FROM CROWN

As is mentioned above an asparagus plant will take 2 to 3 years to produce. But once it is established it can produce for many years. The interesting thing about asparagus is that it is a fast producer. 

It produces new spares every few days in the spring. The weight of the spears is ½ pound per foot of row.

HOW TO PLANT ASPARAGUS FROM THE CROWNS?

  • If you want to protect your plant crowns from weeds, you should plant them deeply.
  • First, dig a trench of about 12 to 18 inches wide and the depth of the trench should be 6 to 8 inches. The gap between each trench should be 3 feet.
  • Remember to soak the crowns in lukewarm water before planting in the ground or raised bed.
  • You should make a 2-inch high ridge of soil along the center of the trench you dig. 
  • Now finally place the asparagus crown on the top of the mound. Make sure the roots of the plant should be spread evenly there should be a gap between each asparagus crown that is 12 to 18 inches.

After planting the asparagus the real work begins. After placing the asparagus crowns in the trenches the next steps are covering the crowns and maintenance of the plant. 

You can fill the trenches by adopting two ways. One is a little-by-little method and the other one is the all-at-once method. 

I will explain the methods one by one so you will understand the whole procedure of planting the asparagus crowns. 

LITTLE-BY-LITTLE METHOD

  • For covering the crown you need compost and topsoil. But bury the crowns only 2 inches deep. Now water the plants so they can adjust to the new environment easily. 
  • Time passes and spears grow to be 2 to 3 inches tall. At this time you need to add 2  more inches of soil. Make sure the spears should not bury completely in the soil.
  • When you see the spears again grow through the layer of the soil. Repeat the process of adding soil to the trench until it has been filled to the ground level. It depends on how deep you dug the trench. It is noted that you have to add soil one to two more times in the growing season.
  • When the trench is completely filled with mound the soil slightly. It prevents water from accumulating around the emerging spears.

ALL-AT-ONCE METHOD

In this method gardeners simply fill the trenches with soil and compost all at once. Most gardeners think that if they grow plants by traditional methods then the plants will be stronger and healthy. 

If the soil of your garden is loose then spears will not face any problem while pushing through to the surface. It depends upon you which method suits you or which method you find easy.

WHAT INSECTS AND DISEASES CAN KILL ASPARAGUS?
