Westland Houseplant Potting Mix, 4 litre, is peat free. It promotes healthy root growth and reduces plant stress, perfect for keeping houseplants happy. Houseplants love being in a mix allowing water to run past their roots instead of sitting in a waterlogged pot. This dry, free-draining mix prevents overwatering and deters flies for healthier, happier houseplants. Enriched with our unique Seramis granules. These granules absorb water and nutrients and then release them to the plant as and when they need it. This ensures your plant keeps hydrated and nourished. The added zinc complex promotes more root growth into your new potting mix, faster re-potting establishment, and also boots your plants resilience. Perlite helps to create the perfect balance of airflow and drainage for healthy root development. Ideal for potting or re-potting most houseplants. Not suitable for ericaceous houseplants such as venus fly traps
