We mix our own potting mix and also sell it by the bag. Bags are 20 quart and are great for potted plants or use as a soil amendment for the garden. We also have 100% worm castings for sale.
Our potting mix is all natural and contains no artificial chemicals.
The potting mix is made with 20% worm casting. In addition to worm castings we add a high quality leaf litter compost, peat moss, coconut coir, rock powder (for minerals), alfalfa meal for N-P-K, and vermiculite to keep the mix loose and capable of retaining both air and water.
You will not find a better potting soil mix anywhere. Please use email in the picture image to contact me, THANKS! plants on the left were grown with worm casting soil and the plants on right were grown in a major brand's
