Peat-free compost has environmental benefits as reducing our dependence on peat means we are not harvesting peat beds and destroying important habitats. However, the peat contains all the beneficial stuff plants need to thrive - and it's good at holding moisture too.
So, without peat, what is our compost being made from? It is primarily wood chip and coconut coir, meaning it provides next to ZERO nutritional benefit for our plants and is not populated with all the beneficial bacteria and fungi either. It has a poor structure, so water goes straight through it, along with any nutrient plant feed in the water. So, although peat-free compost may contribute to saving the planet, it is not nearly as good at growing plants. You may have already noticed this yourself!
