Your windowsill herb garden or patio containers finally have the foundation they need to thrive instead of just surviving. I dove into this Happy Frog mix because it skips the tedious prep work, arriving ready to use the moment you open the bag. What sets this apart from standard dirt is the living component. It is packed with beneficial soil microbes and mycorrhizal fungi that actively work to expand root development.
