Plagron Mega Worm Castings

We thought it was the right time of year to talk about how worms transform organic matter into nutrient-rich castings. Plagron Mega Worm Castings consist entirely of organic worm castings. And, worm castings offer many benefits to your plants.

Worms play a crucial role in the process of decomposition through a method called vermicomposting. Vermicomposting is the breakdown of organic waste materials by earthworms. The resulting product is vermicast, or worm castings. 

How Do Worms Create Worm Castings?

Consumption: Worms, specifically species like Eisenia fetida or Red Wigglers, have a voracious appetite for organic matter. They consume a wide range of materials such as kitchen scraps, garden waste, tree leaves paper, and cardboard. The worms ingest the organic matter, breaking it down into smaller particles in their gizzard.


Once the organic matter is in the worm’s digestive system, it passes through its crop and gizzard. In the gizzard, muscular contractions and the presence of grit grinds the material into smaller pieces. This grinding action exposes a greater surface area of the organic matter, making it easier for microorganisms to break it down further.

Microbial Breakdown

During its time in the worm’s digestive system, the partially digested organic matter moves through the worm’s intestine. Here, it encounters a rich microbial environment. The organic matter mixes with the worm’s digestive juices and undergoes further breakdown through microbial activity. The microorganisms, including bacteria and fungi, help break down complex organic compounds into simpler forms.

Castings Formation

As the organic matter passes through the worm’s gut, it undergoes a transformation. Basically, through the process of digestion and microbial breakdown, the worm converts the organic matter into a nutrient-rich substance known as “vermicast” otherwise known as “worm castings”. Worm castings are essentially worm excrement mixed with beneficial microorganisms.

What Are The Benefits of Plagron Worm Casts For My Plants?

Plagron Mega Worm is a superb source of essential nutrients and live microbial life. Use it to boost or regenerate tired, washed-out soils. The nutrients in Mega Worm are present in forms that are easily accessible to plants. Once you add Mega Worm and water it in, the soluble elements are readily available for uptake.

Nutrient Content: 

Plagron Mega Worm Casts are a fantastic source of essential nutrients required for plant growth. It’s perfect when used to reinvigorate spent soils. It helps to replace washed out: nitrogen, phosphorus, potassium, calcium, magnesium, and trace elements such as iron, manganese, zinc, and copper. These nutrients are present in forms that are easily accessible to plants, making them readily available for uptake.

Improved Soil Structure

Firstly, Plagron Mega Worm Castings enhance your soil’s structure by improving its ability to hold water and nutrients. Worm castings contain a sticky substance called humus, which helps bind soil particles together, improving soil aggregation and aeration. This allows roots to penetrate easily, facilitates nutrient absorption, and encourages healthy root development.

Microbial Activity

Plagron Worm Castings harbour beneficial microorganisms that contribute to the overall health of the soil. These microorganisms promote nutrient cycling, suppress harmful pathogens, and enhance soil fertility. The presence of beneficial bacteria and fungi in the castings can also stimulate plant growth and strengthen the plant’s defence mechanisms.

pH Regulation

Worm castings have a neutral pH, which means they help balance the soil’s pH levels. This is beneficial because many plants thrive in slightly acidic to neutral soil conditions. By regulating pH, worm castings create an optimal environment for plant growth and nutrient availability.

Disease Resistance

The beneficial microorganisms present in Plagron Mega Worm Castings can help plants develop strong root systems. This benefits the plant’s overall health and resistance to disease.

Using Plagron Mega Worm

Using Plagron Mega Worm is really easy. Use it straight up and apply to the soil or add some to the planting holes. It is particularly useful to use to make a compost tea, for rapid uptake via the roots, or used as a foliar feed. Using Mega Worm as a compost tea and applying as a Folia feed coats the leaves in microbes. This works to protect leaves from spores and disease. This is particularly useful to use if plants are exhibiting signs of leaf disease.

Using Plagron Mega Worm Inside and Outside

Use Plagron Mega Worm at the following rates:

  • Outside: top dress or incorporate 1-litre of Mega Worm per 3 – 5 m2.
  • Potting soil: 1 – 2 litres of Mega Worm per 10 litres of potting soil (1:10 or 2:10 – 1 to 2 parts Plagron to 10 parts soil)

Making Compost Tea With Plagron Mega Worm

Plagron Mega Worm Castings can be dissolved in water and fed as a compost tea. Once your compost tea is made, it’s best to use it within 3-4 days and store it in a cool place out of direct sunlight.

Garden tip: You can also use other organic products to make compost tea, such as Guanoklong Complete Soil Mix.

Garden tip: Use 150g of Plagron Mega Worm castings per 4.5l (1 gallon) of de-chlorinated water. For increased microbial activity, add 0.5 tablespoon per litre of molasses to feed and increase the viability of beneficial microbes.

To make Compost Tea:

  1. Start with a bucket or water tank and add enough water for the solution you wish to make. Always use de-chlorinated* water.
  2. Oxygenate the mixture with an air pump for 12 to 24 hours.
  3. After oxygenating, add Plagron Mega Worm Castings (use 150g mega worm pre 4.5 litres of water).
  4. To use the Compost tea, irrigate your plants at the roots or use as a foliar spray.

*Use EcoThrive Neutralise to remove the chlorine/chloramine from tap water. It’s also a good idea to expose tap water to natural light and letting it rest for at least 24 hours and oxygenating with a Hailea air pump, several hours before making the tea.

In conclusion, using Plagron Mega Worm Castings in your gardening is a great idea. Use it either indoors, in plant pots, or outside. Plagron Mega Worm works to bring your plants many benefits that will see them perform at their best. Bigger, better blooms with larger, healthier vegetative growth and more flowering sites, all with better disease resistance.
