My No dig garden in my own backyard is about 100 m2 for about 4 years now.
The difference between the starting point and right now is astonishing!
Before I started my Nodig garden it almost looked like a sandy desert with no soil life. After 4 years it is a garden with a healthy soil full of life, buzzing with insects and some very tasty veggies (almost) year round.
Every creature, from bacteria and funghi, worms and ground dwelling insects, frogs and toads to birds and even slugs, has a place in this little but wonderfull backyard No dig ecosystem!
