For seed starting in pots you’ll want a seed starting soil. Seed starting soil is like Potting Soil but ground to a finer consistency for seed staring. Bot “Potting Soil” and “Seed Starting Soil” are sterilized by heat so there are no weeds, insects or fungal diseases present. They are best for post and containers. Soils labeled “Garden Soil” or “Topsoil” are not sterilized and are for adding to dirt on the ground…not for use in pots.
