KC Gardens

Was it bad garden soil?

I purchased a garden soil mix for my gardens from a place that was highly recommended to me and none of my gardens grew. I watered as needed and understand that the heat had something to do with it but my shade garden was stunted nothing grew over 4 in tall. I have never had impatients be stunted.what can I do to improve this soil. I also added compost to it prior to planting. - Lita -
