Soilblock Recipe

Here’s our soil block recipe that we use. Sometimes we’ll add more compost to a mix depending on how much fertility we feel the compost has. We mix our soil in an old mortar mixer. That’s the type of mixers that have paddles and actually churn the mix instead of a concrete mixer that just spins and turns the mix. We always mix the ingredients dry first (You’ll notice on the recipe it says “mix” after a series of ingredients are added. This helps you end up with a even mix) and then add the water. How much moisture? Well that’s where the artisan skills come into play. Probably more than you think but not so much you end up with a soup. And remember, the peat moss absorbs a lot of moisture over time so if you wet it down, leave, and come back you’ll generally find a much drier mix than you started with. Ideally I aim for a mix that I can grip in a handful and squeeze a fair amount of water out when my grip is closed.

How’s that for non specific in terms of moisture? Email me if you need more input.
