Additional Information

Dirtcraft Peat-Free Mixes

Founded in 2018 and peat-free from day one, Dirtcraft blends high-performance, biologically active potting soils using the most local and renewable ingredients available. Their soils are all compost-based because as they assert, “Living soil with a diversity of beneficial microbes is the secret to plant health, vigor and disease resistance.” In Fedco’s peat-free trials, Dirtcraft soils have yielded the healthiest plants with the most vigorous root systems. Peat-free is the way to be!

Peat-free mixes hold water differently than peat-based mixes; peat dries from the bottom-up, whereas peat-free dries from the top-down. Resist the urge to overwater! Use a popsicle stick to probe the center of a cell to see if the tray needs water—overwatering can inhibit good germination.

Why go peat-free?

Peat is an extraordinary horticultural material, but it is mined from peatlands, which are beautiful and remarkably biodiverse ecosystems that deserve preservation. What’s more, peat bogs sequester an incredible amount of carbon; it’s estimated that per square meter, they hold 500% as much carbon as the Amazon rainforest. Let’s wean ourselves off peat right away!
