In addition, this potting medium is made with ingredients to help your indoor plants thrive: coir to increase air space and moisture holding capacity, sphagnum peat moss to help retain and release water, and quick-start natural fertilizer that provides immediate nutrition. Great for seed starting, this indoor gardening soil is for use with any indoor container plant, including houseplants and herbs. For best results, select containers with drain holes. To plant new seeds, fill a container with potting mix. Plant your seeds according to the package directions, and water thoroughly immediately after planting. Keep the soil moist and out of direct sunlight. To use with transplants, partially fill a container with potting mix. Loosen the plant's root ball and place in the pot. Cover with more mix and press lightly. To finish, water thoroughly and let it drain. One 16 qt. bag of potting mix fills one 12-inch container.
