Fine zeolite is a clever little component that supports delicate roots while keeping nutrients where they're needed. This smaller grade of mineral helps retain fertilisers and moisture, making it perfect for use in propagation mixes or with young plants. It improves aeration, reduces the risk of root burn, and holds structure over time without breaking down. Ideal in blends for seedlings, cuttings, or compact root systems - fine zeolite gives your most precious plants the best possible start.
