Your soil is alive. Like, really alive. It's not just dirt—it's a whole underground city of bacteria, fungi, worms, and tiny critters all working together.
At the base of this food web are decomposers (bacteria and fungi) breaking down dead stuff and making nutrients available for the plants. This creates healthy, living soil that actually supports your plants.
To keep this ecosystem happy, avoid excessive tilling, feed the critters with organic matter like compost, and skip the chemical pesticides that kill the good guys too.
