If you mulch it, they will come.
When we first bought our property, we started right in on soil improvements where we knew the vegetable garden was going to be, long before we even had house plans finalised. That work was terribly depressing. The topsoil had been stripped off by the developer, and what was left was compacted clay studded with rocks. It barely grew weeds, and the combined effort of a rotary hoe and hand tilling only managed to penetrate about 5 cm into the soil. There were no worms, no beetles—and we later learned, no nutrients either.
I wondered if we’d made a huge mistake buying the land.
Since then, we’ve poured compost and manure into the soil, mulched heavily, and done our best to avoid compacting the soil so painstakingly loosened.
As I began turning beds this spring, I was stunned by the number of worms in the soil—thousands upon thousands of them. The clay is honeycombed by their tunnels, and you can’t dig a hoe in without bisecting a few (sorry!). It is truly astonishing.
Where did all those worms come from? Were they there all along, but hiding deep below the surface? Did the few worms there when we first moved in simply reproduce like mad when we started adding organic material to the soil? I’ll never know, but I begin to have hope for this garden.
I feel a little like Ray Kinsella (Kevin Costner) in Field of Dreams—create the right conditions, and the players will appear.
