CPP: Biodynamics for Beginners

The Biodynamic Cow Pat Pit Preparation

I’m interested in exploring biodynamics in my gardening, where should I begin?

I think depending on who you ask, you could get dozens of answers to this question.

I have a handful of responses, depending on the kind of person I’m talking to, if I’ve seen their garden and had a chance to feel for myself what I would do next. It’s a tricky question to answer, as I feel like people sometimes want to simplify a way of life that is incredibly deep and complex.

Some possible starting places are:

  • Go visit a Demeter certified biodynamic grower and spend a day working with the soil — does anything speak to you or spark fascination?

What is CPP?

Put simply, it’s cow manure which is mixed with a little crushed egg shell, some volcanic rock dust, kneaded for an hour, and then has the six Biodynamic compost preparations added to it: yarrow, chamomile, stinging nettle, oak bark, dandelion and valerian. Traditionally this is stored in a brick-lined pit in the ground for a few months where it transforms from fresh manure into fine humus containing all the goodness of the compost preparations.

How do I use the CPP?

To use the CPP, you take a small handful and mix it in a bucket of warmed up rain water. Stir the mixture to create a vortex, like a whirlpool effect, and then change the direction of stirring to create a vortex going the other way. Repeat this backwards and forwards stirring action, alternating between creating order and then disrupting with chaos.

After 15–20 minutes you can then use the liquid over your garden, your seedlings, your lawn, and even your houseplants.

It’s a fabulous way to promote soil health, and for newcomers to Biodynamics it’s a nice way to start making your own preparations. If you don’t have bricks to make a pit, experiment with different sized terracotta pots, and dig them into a free draining section of your garden. You want the mixture to be able to breathe, but to not get rained on — I use a terracotta saucer over the top of the terracotta pot.

If you want to try it before you make it, then I’d recommend joining the Biodynamic Association where you live, and sourcing some from a preparation maker in your local area.

For other tips on incorporating biodynamics into your home gardening, here’s another perspective.

Happy stirring!
