One way of reducing waste, packaging and shipping, is to make your own at home. The RHS gives this recipe for making potting compost:
Make your own potting compost: For potting on and containers:
4 parts loam (soil)
1 part garden compost, municipal green waste, or well-rotted manure
1 part leaf mould
1 part sharp sand
1 heaped trowel of seaweed meal per loaded wheelbarrow
This is a basic mix. Add more sand for alpines and herbs, and use composted bracken instead of garden compost for acid-loving plants like blueberries.
