Cultivating Asparagus in Your Aquaponics Garden
To learn more about growing Asparagus in aquaponics gardens, we have here some of the most practical knowledge that you can use right away.
Aquaponic System Types
We recommend using the Deep Water Culture or DWC for your Asparagus so that you can easily check its roots. Media bed is also a good system most especially for beginners, or if you do not have the right equipment for DWC.
Since Asparagus works best in neutral to slightly acidic pH levels, you should maintain it between 6.5 to 7.
Clay is a good option for growing Asparagus, but you need to make sure that it is well-drained. We do not encourage using recycled grow medium for this vegetable in order to avoid diseases.
Water and Air Temperature
Generally, Asparagus flourishes in warmer climates. Your water temperature should be around 75 to 85 degrees Fahrenheit. If you have colder water, we suggest that you get a water heater.
As for the air temperature, 70 to 80 degrees Fahrenheit will do your vegetable good. If it goes lower than 24, your plant will likely be damaged or worse.
If you are using a hexagon-based grid, the space between your Asparagus crowns should be around 15 – 18 inches.
Asparagus loves sunlight and it must be exposed for at least 8 hours every day.
In addition, you can use shrimps for your aquaponics too. But remember to separate it if you have existing fish in your system.
It will take three years to harvest the Asparagus shoots. This is the reason why Asparagus is more expensive than most vegetables. We do not recommend to harvest all the shoots in one go. Doing so might delay the growth of other shoots, and you will have to wait for several months again.
There are a number of pests that can damage your Asparagus. Some of the common ones are aphids, armyworms, beetles, cutworms, grasshoppers, and larvae. You should have artificial controls in place to combat these pests at the onset. However, make sure that your pest solutions will not harm your fish.
Asparagus rust is one of the most common diseases of the vegetable. If your plant is infected, you will notice a reddish-brown on the plant’s stems and leaves. This happens when you are in a humid environment. The best solution is just to cut the disease or the affected area.
Before we close this article, here are some words of wisdom if you wish to grow your own Asparagus in an aquaponics system:
- Using Asparagus crown is easier than planting seeds
- Make sure that the crown is free from any disease
- Never grow a different type of plant or crops in the same bed as the Asparagus roots can grow big
