‘Mixing Frass into Your Potting Mix Getting a new batch of pots or containers ready for the season? Work our Insect Frass through your soil or soilless mix at 3-5g per litre before you plant. Mix it in well so it’s spread evenly through the medium — this gives young roots steady access to nutrients right from the start.
Top Dressing Through the Growing Season Established plants benefit from a regular top-up. Sprinkle 10g per 15-20L pot around the base, and water well. Repeat every 2-4 weeks through the growing season, adjusting to how your plants are performing.
Feeding Seedlings and Cuttings Young plants need a gentler touch. When potting on seedlings or cuttings — particularly into coco coir — use a lighter rate of 1-2g per litre. This lets them settle into their new home without overloading them, so they can build strength gradually. See our Online shop for further information.
