Setup, Compatibility & Care
- Mixing: Incorporate the grit thoroughly into compost using a hand trowel or spade for a uniform mix. Aim for a ratio of 1 part grit to 3 parts compost for general use, or up to 1:1 for cacti.
- Compatibility: Safe to use with all general-purpose, multipurpose, and seed composts. It is also suitable for use in the base of pots to assist with drainage, though ensure the drainage holes are not blocked by larger stones.
- Care: Keep the bag tightly sealed in a dry, covered area to prevent contamination with seeds or debris. As it is a natural mineral product, it does not expire, but keeping it dry makes it significantly lighter and easier to transport when needed.
