Description

Sol Soils Seedling and Propagation Mix is a fine, moisture-retentive, peat-free mix for starting seeds and rooting stem or leaf cuttings. It is much finer than the Sol Soils chunky and gritty blends and works with every plant type you might start from seed or a cutting.

The organic part is coconut husks, hardwood biochar and earthworm castings, and the mineral part is calcined clay. Together they give seeds and young roots steady moisture, good oxygen flow and drainage. The mix is packed with beneficial microbes, so you may see a little white mycelium in the bag. That is expected: blend it through and plant as is.

Because the mix holds moisture and is blended and bagged by hand, its color can vary from bag to bag, and it looks lighter dry than damp; the recipe is the same. It also makes a good first soil for tissue culture plantlets, and you can blend it up to half and half into another Sol Soils mix for a finer, more moisture-retentive hybrid. It is not meant to be a long-term home for mature plants.

What is in the bag: 4 quarts (1 gallon) of coconut husks, hardwood biochar, earthworm castings and calcined clay.
