How To Add Worms Into Your Aquaponics System?

Worms are one of the best things you can add to any garden.  This is because they are great at breaking down organic debris and creating fertilizer for your plants. 

They like to live underneath the soil and make tunnels while they forge for food.  These tunnels are great for aerating the soil and allowing for plant roots to breathe. 

In order to use worms in your aquaponics system, you can bury some worms directly into your soil.  As long as they receive food, they will continue to work in your garden.

Keep in mind that if you want to put worms directly in your grow beds, you will most likely need to add additional organic material for the worms to consume.  Worms like to eat anything that comes from nature.  

organic material for the worms to consume

Some good food you can add is dried leaves, cardboard, or rotting food.  Keep in mind that as organic material breaks down it creates a lot of heat.  If you apply too much to your plants, it can burn them.

Worms have small mouths so if you want to make food easier for them to digest, tear them into small pieces before putting them in the soil.  As mentioned before, worms can quickly multiply when they are in favorable conditions.

In some rare cases, your worm population can get so big that the worms end up eating the roots of your plants.  The best way to avoid this problem is to monitor your soil on a weekly basis.

Take a soil sample to analyze how the worm population is expanding.  

If you think there are too many worms, you can remove some of them and put them into another grow bed.  They will happily do good work wherever you put them.

Can Worms Drown In Aquaponics?

Just like humans, worms need oxygen to survive.  If your grow beds do not have proper drainage water may start to build up in the soil.  When worms are underwater, they can not breathe. 

If they are left underwater for too long, they will die.  You will notice them spilling over the side of your growbed. Not only is excess water bad for your worms, but it is also bad for your plants.  

In aquaponics, you need to make sure that your beds have proper drainage.  This will allow for the plants and worms to develop healthily over time.

To start off using worms, try to put half of a handful of worms per square foot of soil.  If you are in a rush, you can add a full handful per square foot of soil.  Keep in mind that the more worms in your soil means there needs to be more organic material for them to consume.

Worms like to live in a moist environment.  So as long as your flood and drain cycles are set correctly, they should like to be in an aquaponics bed.  

According to North Carolina State University, “Vermicomposting is the process of earthworms turning organic debris into worm castings, the fertile waste product of earthworms.”  This worm compost can be made into a very useful tea.  

To do this, take a scoop of soil that contains a lot of worms.  Screen the soil so that all the worms are removed.  From here, you need to soak the soil in a bucket of water using an old t-shirt.  

The resulting liquid is an excellent fertilizer that can be sprayed on all of your plants.  This will help your plants grow in no time! Hopefully, now you know the answer to the question: how many worms per square foot in aquaponics?
