How Deep Do Asparagus Roots Grow: Find Out Here

how deep do asparagus grow

Some articles suggest the evacuation of an 8-inch and making a refill as the asparagus stalks grow. The setting of crowns four inches deep can’t hinder the growth as the new stalks can find their way up through the soil. Asparagus possess contractile roots which pull the crowns down to a spot they prefer gradually.

Asparagus tends to perform better if planted two feet apart. After about some time, you will discover that the root systems will become huge. If the asparagus plants are planted too close together, the asparagus plants will yield new stalks for only a small number of years. As long as there is enough space coupled with good care, the crowns should last 20 years and above.

Weeds are found everywhere and anywhere and so can be found amongst asparagus plants. When removing weeds, take proper caution so as not to end up killing the asparagus. It is much simpler to keep asparagus weed-free during the early stages of growth than to make attempts to dig out weeds in the late stages of growth.

If proper care is not taken, you might end up killing the asparagus stalks. A clean perimeter edging or surrounding path prevents the growth of quack-grass on the bed. It is much better the bed is cleared of weeds as asparagus plants can’t compete with them and will rather give up.

Avoid cutting the stalks while the asparagus is still establishing its root system. You can begin the following year and you reap your first rewards. A simple determination of what to cut without causing harm is to make the harvest of stalks with a minimum diameter of a lead pencil and to quit harvesting on the fourth of July.

Asparagus has a deep root system and the roots can get very long and can reach a depth of 10 feet and can even more. Note that when growing asparagus in raised beds, there must be enough room. This automatically means the raised beds must be large enough to continue the asparagus growth. When planting asparagus crowns, ensure the trench is about 12 to 18 inches wide and 6 to 8 inches deep.

With the deep root system of asparagus, it is important the soil is loosened to 12-15 inches in depth. This is to allow the asparagus crowns to root properly and prevented them from being disrupted by rocks or other obstacles which might be present.

Note: Asparagus plants must be planted at an appropriate depth. Planting asparagus seeds too shallow will result in them getting rotten before even getting the opportunity to sprout. Asparagus crowns are also similar. If not planted at an appropriate depth, they won’t possess the requirements needed to obtain healthy root systems. Asparagus sinks roots up to 10 feet deep and produces delicious stems which can take up to 15 years and even much likely more than that. It is a vegetable but can’t be compared with a tomato or a pepper plant. As explained earlier in this article, existing weeds should be removed as asparagus yields best when there is an absence of competition.
