Bark peelings from local managed woodland. Ideal both for use as mulch and for pathways. Bark mulch will stop weeds, and helps water retention in droughts. It aerates and feeds the soil as it biodegrades.
This potting grade bark can be used alone as a growing medium, or add it to homemade or proprietary potting composts.
It will improve drainage, looks decorative, and has a lower pH. For a professional appearance, use it for dressing pots.
