Lime-free washed granite angular grit - RHS endorsed product - large pack.
Ideal for adding to composts, ponds and aquatic planting, drainage in pots and tubs, alpines and rock gardens and improving drainage of heavy soils.
Adding horticultural potting grit to your compost prevents soil sticking together allowing excess water to freely drain away.
For ponds and aquatic planting, apply a thin layer to the top of the container. This will prevent fish from stirring up the soil.
Please note: products made up of natural materials will vary in size and colour
