The answer is under your feet....
Did you know - a teaspoon of rich garden soil contains billions of tiny microscopic life forms living & loving the day away?
And the by product of all their activities create the perfect environment for plants?
It makes perfect sense to care for them (it's that scratch my back I'll scratch your back thing)
Do what you can to make the right environment for them in your grow beds - and in return they'll make sure your veggie's grow a bumper crop!
