Quality soil mixes are ideal for establishing healthy transplants and container gardening. When starting seedlings, it is always best to start them in a seed starting mix rich in nutrients. This allows the young plants to easily punch through the lighter soil mix and quickly establish roots. Plants grown in containers need nutrient rich soil, that is well aerated and drains well while still being able to retain moisture for plant growth.
