Builder’s Bag Planter Mix

£71.25 inc VAT

Our Caledonian Planter Mix is a peat-free growing medium filler mix made from a blend of Green Goodness, composted bark fines, and basalt rock dust.

Ideal for using in raised beds and garden borders, our Planter Mix is guaranteed to be weed free and provide a more competent growing mixture than using our Green Goodness on its own, which needs to be diluted to allow for the slow release of nutrients and a more sustainable top growth.

The added rock dust provides valuable minerals and nutrients that promote healthy longer lasting plants as the rock dust slowly breaks down.

This high quality peat-free Planter Mix is made from green and woody material collected from gardens and parks throughout the Scottish Lowlands. We then shred and compost this material in large windrows at our composting sites, which are aerated and monitored in order to achieve the temperatures required to kill weeds and pathogens.

    Great service from the team, with bags delivered with great care. Being used for new raised beds – too early just yet to see any results!
