Our Seedling and Propagation Mix is perfect for seed starting or propagating a stem or leaf cutting. It is designed to be much finer and moisture retentive than our other mixes and is compatible with all plant types. The components in this mix provide seeds and seedlings with an ideal physical structure ensuring adequate water retention, ideal oxygen flow, as well as excellent drainage. Our core chunky & gritty mixes are built for more robust root systems, but this mix is compatible with all plant types that might need to be started from seed/cutting. Because it is more moisture retentive, you may see color variation bag-to-bag (we still mix and bag by hand!). WHAT’S IN IT Coconut Husks, Calcined Clay, Hardwood Biochar, Earthworm Castings Since the mix is full of beneficial microbes, they want oxygen to keep doing their thing. We recommend poking the back a couple times with something small and sharp to let oxygen flow. We'll have holes pre-punched in our next set of pouches!
