Soil Mixes

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.

Selecting Soil Mixes for Your Growing Needs

Choose seed soil formulated for germination when starting transplants. Seedling mix products feature a finer texture and lighter composition that allows emerging roots to establish quickly. Consider sterile, soilless options to minimize disease pressure in propagation.

Match your soil mix to the growing stage and application. Container production requires mixes that balance drainage with moisture retention and nutrient availability. Look for formulations suited to your crop type and production scale.
