Product Details

How to Use

Garden Beds

Spread an even layer around plants and lightly incorporate it into the upper soil. Water thoroughly after application and cover with mulch if desired.

Established Pots

Apply a thin layer to the surface of the potting mix, keeping it clear of the plant stem. Gently work it into the upper layer and water well.

New Potting Mixes

Blend the castings thoroughly through the potting mix before planting. Avoid using worm castings as the sole growing medium.

Planting

Mix a modest quantity through the backfill soil before planting. Do not place a concentrated layer directly beneath sensitive roots.

Seedlings and Young Plants

Use sparingly and mix thoroughly through a suitable seed-raising or potting medium.

Always follow the application directions printed on the product packaging if they differ from this general guidance.

Frequently Asked Questions

What are worm castings?

Worm castings, also known as vermicast, are the finished material produced as composting worms process organic matter. They contain organic material, plant nutrients, trace elements and beneficial microorganisms.

Are worm castings the same as compost?

No. Both improve soil, but worm castings are generally finer and are commonly used in smaller quantities as a concentrated soil amendment. Compost remains useful for adding larger quantities of organic matter.

Can I use worm castings on vegetables and herbs?

Yes. They are suitable for vegetable gardens, herbs and other edible plants when used according to the package directions. Always wash harvested produce before eating.

Can they be used on indoor plants?

Yes. Apply a light top dressing or mix a modest amount through fresh potting media. Avoid excessive application and ensure the pot drains freely.

Can I plant directly into worm castings?

Worm castings are best blended with soil or potting mix rather than used as the sole growing medium.

Will worm castings burn plant roots?

They generally provide gentle nutrition, but excessive use can still affect the balance and drainage of a growing medium. Apply conservatively and follow the package directions.

Do worm castings replace fertiliser?

They contribute nutrients and support nutrient cycling, but they may not provide every plant with all the nutrition it requires. Additional fertiliser may be needed depending on the plant, soil and growing conditions.

Do worm castings control pests and diseases?

Worm castings are not a pesticide or fungicide. By supporting healthy soil biology and plant growth, they may contribute to plant resilience, but they will not prevent or cure every pest or disease problem.

What should worm castings smell like?

Good-quality castings generally have a mild, earthy smell. Colour, texture, moisture and aroma may vary because this is a naturally produced material.

How should the bag be stored?

Keep the bag closed in a cool, shaded and dry location. Protect the contents from excessive heat, direct sunlight, drying out and waterlogging.

Can worm castings be used with other fertilisers?

Yes, but consider the total amount of nutrients being applied. Introduce combinations conservatively and follow the directions for every product used.

Is a 10L bag the same as 10kg?

No. This product is sold by volume. Its weight can vary depending on moisture content and natural batch variation.
