Plant Magic Plus Soil SupremePlant Magic Soil Supreme is a customer favourite at One Stop! Growers everywhere choose Soil Supreme because it's easy to use and the quality has stayed consistently high over many years. It features a blend of sphagnum peat and fytocell foam that's enriched with organic growth stimulants. It has a lovely, fluffy consistency and is only lightly fertilised, so there's no risk of causing burning when potting up younger plants. Very highly recommended.
