Westland Orchid Potting Mix, 4 litre, is a dry, free-draining, peat free mix preventing over watering and deters flies for healthier, happier orchids. Orchids love being in a mix which lets water run past their roots instead of sitting in a waterlogged pot, so this mix is perfect. The added zinc complex promotes more root growth into your new potting mix, faster re-potting establishment, and also boosts plant resilience. Added pine bark creates the perfect balance of aeration and drainage for healthy root development. Enriched with Seramis which absorbs and releases water to keep your orchid hydrated and nourished, as and when they need it. Perfect for all your orchids such as Cymbidium, Dendrobium, Miltonia, and Vanda types.
