Midwest Hearth Seed Starter Potting Soil is a ready-to-use potting soil mix. It has been specially formulated with a soil mix combination of organic peat moss, perlite and vermiculite. This formula provides excellent seed germination and growth of young seedlings. The soil will drain well and is highly organic. The organic nature of the soil will help in the nutrition of your plants. A weight and color change in this potting soil from dark brown to light brown assists you in deciding when to water. Generally, you want to plant the seed at a depth of 3 times its diameter. This will provide adequate contact with the seedling media and the seed to insure excellent germination as long as appropriate temperature and moisture are maintained in the soil mixture.
