If you do a lot of container gardening you probably already know that your soil needs to be light and fluffy and full of nutrients since the roots can’t go anywhere but in the container you have to supply what the plants need. They need to be able to work their way down through the soil so that is the reason for light and fluffy. Good potting soil that you buy in bags can get expensive if you use a lot and the soil in a container should be replaced if you plant tomatoes in it but you can plant other things in it just not tomatoes.
You can use coconut coir instead of the peat called for and if growing veggies I would add some Azomite Rock Dust to provide the plants and thus my family with the 67 major and trace elements it contains. The other nice thing about this great potting soil is that you can move your containers around if you wish because it is very light unlike packed down from watering soil.
