  • 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. 


  • 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.


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.
