For those looking for a peat-free potting compost, our multipurpose is carefully blended from a mix of composted coir (cocofibre), fine bark chippings for aeration, and a sterilised mixed organic green waste. This is then topped up with a 5:6:10 NPK fertiliser, plus 2.9% magnesium, which gives all plants a good start in life. The peat-free compost is fine enough for seedling and cutting use, yet coarse enough for general purpose potting on into tubs, baskets or pots. You may find this compost needs slightly less water than peat-based composts, otherwise treat them exactly the same.
