Interested in hydroponic asparagus? 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, and 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 indoor 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 them 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 started with asparagus hydroponically, you will need to propagate asparagus plants.
Asparagus plants can be propagated in two ways, either from seed germination or from crowns.
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 crowns 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 stocks (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 the asparagus crowns gotten from the field into your hydroponics system. Ensure you also make a sterile environment for the transition into hydroponics and take other precautions.
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 of 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.
The 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 all in one 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.
Harvest spears when they are 5 to 7 inches long. Harvest spears by using sharp tools to cut or simply snap them off.
How to Grow Asparagus From Cuttings
Growing asparagus from cuttings couldn’t be easier. You can do it either one of two ways: using the soil method or the water method. Let’s take a closer look at both options.
If you’re a beginner, this is probably the best method to use, as it is the easiest. All you need to do is:
- Prepare your cuttings. Cut from a fresh plant, and do not use old asparagus cuttings, for best results.
- Clean your cuttings. Run under cool water and remove any dirt or insects that may be on your cuttings.
- Cut. Remove any roots on your cuttings. However, you need to leave at least 6 inches, for best results.
- Prepare your soil. Prepare the soil by making it moist with water.
- Plant. Place your cuttings into your soil; around 2-3 inches below surface level.
- Mist. Mist your cuttings now, rather than pouring water o them, for best results.
- Check regularly. After a week or two, you should see your asparagus beginning to grow.
This method is a little tricky, but better if you want to watch your asparagus as they grow.
- Prepare your cuttings. Much like above, cut from a fresh plant and wash them under cool water to ensure they’re clean.
- Place in water. Fill a clear container with water.
- Add cuttings. Place around 75% of the cutting into water, so the top is sticking out. Over time, you’ll notice your water may change color or become slimy. If this happens, be sure to change the water.
- Check regularly. After a week or two, you should see your asparagus beginning to grow. Hand-Picked Nursery Asparagus Planting Instructions
The asparagus from Hand Picked Nursery is infamous in the gardening world and you may be wondering how to plant them. Let’s take a closer look.
Buy your asparagus and then remove it from the bag once ready to plant. You may want to rinse them before use and then leave them to air dry. For the soil, you’ll need well-draining. You should ensure there’s ample space and depth for your asparagus. For example, each row should be at least a few feet apart.
pH For Asparagus – What Should it Be?
As mentioned above, asparagus must be grown in well a drained soil. As for the type of soil, sandy or medium is best. The pH should be anywhere between 6.5-7, which is only just slightly acidic. Any more acidic and your asparagus will not thrive. You can test your soil if you’d prefer,r and add fertilizer according. However, be sure not to use a herbicide fertilizer, as this can cause more harm than good.
Asparagus Water Needs: How Much Do They Need?
You may be wondering how often you need to water your asparagus. Typically, they are around an inch or two per week, up until they’re around two years old. At this point, they have reached full maturity and will only need around an inch of water per week. These are the best rules to follow when deciding how often to water your asparagus.
Conclusion on Hydroponic Asparagus
Now, we have seen that hydroponic asparagus is possible with the right comprehension. Make sure to follow our guidelines and we wish you successful asparagus growing. Do you have any tips when it comes to hydroponic asparagus? If so, please feel free to let us know in the comments below. And remember, sharing is caring!
Can asparagus be grown hydroponically?
Yes, it can. You will need to fertilize it with a fertilizer that is specifically designed for hydroponic growing. Hydroponic growing is much easier than potting up seedlings, and there are several advantages to using hydroponics instead of soil.
There are many different ways to grow asparagus in a hydroponic system. The simplest way is to use a plastic tub and place the asparagus spears in it. The water will be pulled up through the bottom of the tub. If you have a shallow tub, then the spears may be planted close together. Otherwise, you can plant them several inches apart. Asparagus is a heavy feeder.
It loves nitrogen. So, if your growing space is limited, consider using some fish emulsion or blood meal (available at most nurseries) as a fertilizer. The second method is to place asparagus in a floating container. This allows the roots to grow directly down into the water. Floating containers are available from many online retailers, but be careful to avoid the ones that are too large or too small. There are also a variety of hydroponic systems on the market. Many are designed for the home gardener. They come in all shapes and sizes. One of the more popular hydroponic systems on the market today is the NutriWave. These systems allow you to grow your own vegetables with very little effort. It has a vertical growing chamber that holds the nutrients and water. The plant roots go directly into the nutrient solution. This is a great way to start if you are new to growing.
The best time to harvest asparagus is when it is just beginning to flower. When the stalks are about six inches tall, pick them and enjoy.
What's the best nutrient solution to grow asparagus hydroponically?
There is no best nutrient solution for growing asparagus. The answer depends on what you mean by "best". What will work best in your particular situation will depend on a lot of factors.
Asparagus is one of those crops that you can grow very well in a hydroponic system. However, it takes some trial and error to find the right combination of nutrients for your plants. In this case, I've had good luck using the following nutrient solution: 2-1-1 Solution (Soltan) Soltan is an all-purpose fertilizer.
The only thing that I have changed from the package directions is that I add 0.2 grams of Sequestrene per gallon of water. This is because I use more than 1 gallon of water per gallon of soil and Sequestrene is a slow release fertilizer. Soltan's website says that it is safe for use in a hydroponic system, but I prefer to be extra careful when dealing with fertilizer. If you're concerned about using a fertilizer that is not specifically designed for use in a hydroponic system, then you could also try mixing Soltan with your regular garden fertilizer. The amount of nutrients that you need depends on what type of asparagus you are growing.
What type of irrigation system can I use?
You can use a drip irrigation system with a 4-inch tube running from the water tank to my pots. I have found that it is best to set the timer on the drip system to run for about 15 minutes before setting it to turn off. I do this because I don't want to waste water by having the drip system run all day. I have also found that the drip tubing needs to be replaced every six months or so. I use PVC tubing that comes in 2-, 3-, and 4-inch sections. I use a hose bib to connect the tubing to my water tank and then to my drip irrigation system. I have attached my drip system to a PVC tee and then connected the other end of the tee to the bottom of my pots. I have also attached an extension piece to the top of the pot. The extension piece allows me to easily remove the pots and move them around. This way, if I want to rotate the plants, I can move them without having to take them out of the water.
Is it a hardy plant?
Asparagus is a hardy plant and can withstand a wide range of temperatures, so you should be able to grow it indoors year-round without a problem.
