Sheep pellets are an easy and convenient source of organic matter which are great for improving the soil structure, encouraging earthworms, and naturally feeding your plants. They can be applied liberally to the soil surface at any time of year or mixed with soil. It is perfect for mixing with soil when planting a tree or shrub. The NPK rating is 4:1:4 and releases these nutrients in a controlled and slow manner. We recommend using two handfuls per shrub or 2-3 handfuls per square metre.
