  1. Many years of using this
    I’ve used G&B raised bed mix and their soil building conditioner for over 20 years. I bought my home home and it did not have any flower beds or raised beds. As I made my in ground flower beds I amended with the soil building conditioner. I amend every 6 months and have achieved a beautiful soil mix that will grow anything I desire!
    Love the stuff!
