Ditch the Double Digging?
Every spring, and then again every fall when the season's harvest is over, I double-dig my raised beds: I clear the beds of all remaining plant material, then plunge a shovel into the soil and dump it to the side of the hole. I continue this until all the soil in my 4' x 8' bed has been turned. Then I sprinkle a bag of composted cow manure, peat moss, compost, bone meal and blood meal on the soil and repeat the process to mix the amendments in. I thought this was a means of replenishing the nutrients and improving the soil. But I just came across a video from my revered gardening guru, Paul James, that suggests that I may be actually harming the microorganisms in my soil. He suggests to instead use a pitch fork or broad fork to "stab and rock" the soil, basically aerate it. It certainly would be a less labor-intensive approach than my double-digging, but I'd like to hear from others who take this approach.
