Interested in growing asparagus hydroponically? If yes, we will enlighten you about it in this article. The tasty asparagus vegetables can be grown hydroponically with the right knowledge and you will enjoy amazing benefits from it.

Asparagus is a temperate zone plant thus requires warmth for optimal development. You can grow asparagus successfully with hydroponics if you supply them with their required growing needs. We will enlighten you on all the requirements and more so, read on to discover how to go about it.

A Little About Asparagus

Known to be warmth-loving plants. In fact, during the cold period, it goes into dormancy to stay alive. This shows it will be great for warm indoors hydroponic farming where you can comfortably adjust the environment to suit its growing needs.

You can even grow them all year round in your indoor hydroponics without worrying about it going into dormancy. All you need do is to supply it with good warmth in your indoor hydroponics garden to serve you all year round.

Guidelines On Growing Asparagus Hydroponically

To get starting with asparagus hydroponically, you will need to propagate asparagus plants.

Propagating Asparagus

Asparagus plants can be propagated in two ways, either from seed germination or from crowns.

  1. Propagation By Crowns

Asparagus propagation by the crown will give you a quick result compared to seed germination. The crowns of asparagus are simply one-year-old roots of asparagus which has been grown from seeds. Therefore, they are simply roots ready to be planted. You can purchase asparagus crown from a garden center or nursery store near you.

Usually, they should be sold to you as planting stock that comprises a root system and central fleshy crown. However, you should be aware that these plant stock (crown and root system) are grown in the soil or field. Thus, they will most likely convey soil-borne diseases into your hydroponic farm.

This is why you need to be very careful when it comes to growing asparagus crown gotten from the field into your hydroponics system. Ensure you also make a sterile environment for the transition into hydroponics and take other precautions.

  1. Propagation From Seeds

Asparagus propagation from seeds is also possible. However, it is time-consuming and requires lots of patience as it can take up to a year of growth until harvest time. The good news is that once it gets to the crown stage, asparagus can be grown continually for more than a decade. Properly take care of them and you continually enjoy spears of asparagus for a long time!

Germination of asparagus seeds can take up to 10 to 15 days. Simply maintain a temperature around 71 degrees to 79 degrees Fahrenheit. Avoid lower temperatures as this can make their growth process slow.

Once you start to notice germination of about 3 to 5 inches and they have some root growth: you can transplant them into your hydroponics system.

As they continue to develop in the hydroponic system, you can supply them with warm temperatures of around 75 degrees to 86 degrees Fahrenheit. This will enhance the developmental rate of the young growing crown and foliage. You can as well introduce light with gradual intensity as the plant matures.

Hydroponic System To Use

There are various hydroponic systems to make use of. However, we recommend a Dutch bucket system, deep water culture, or Kratky system to raise your asparagus plants.

Ideal Nutrient Solution For Growing Asparagus Hydroponically

A well-balanced nutrient solution suited for the vegetative stage is ideal for it. Use this for the entire active growing stage of hydroponic asparagus.


Now to the harvesting period which is our most anticipated period: you can begin harvesting the first year after planting. Just make sure you harvest a few spears from each plant. Don’t do this at a go, do it for about 2 weeks and stop till the next harvest.

This way, you can give them a chance for the fronds to unfold and continue to develop a strong root system. It will also encourage them to conserve the energy required to generate plentiful spears the next season. In the next harvesting period, you can increase the harvesting time to 3 weeks and stop till the next season.

Harvesting Asparagus

Harvest spears when they are 5 to 7 inches long. Harvest spears by using sharp tools to cut or simply snap them off.
