Our premium Peat-Free Houseplant Compost contains the perfect balance of coconut coir (a by-product of the coconut industry) mixed with slow release Plantsmith nutrients that feed and nourish houseplants for up to 6 months. Designed for the widest range of houseplants, it’s suitable for everything except orchids, cacti and bonsai trees. The compost is compressed into a block and is super easy to activate by just adding water to make up to 10 litres of nutrient rich compost for healthy houseplants.
