The BEST Tool For Starting Seeds: The Soil Block

August 16, 2012

The summer CSA is well underway. Plenty of delicious and colourful vegetables are growing in the garden and in the greenhouse, with more on the way.


Gardening requires a lot of planning and preparation, which is why we’ve started sowing seeds for the winter CSA. With the help of the wonderful Eliot Coleman‘s book, The Winter Harvest Handbook, we are learning the ways of winter farming.

For a successful winter harvest, cold-hardy vegetables must be planted. There are about thirty vegetables that can tolerate cold temperatures. Turnips, chard, leeks, kohlrabi, red russian kale, pak choi, winterbor kale, and mesclun lettuce are some of vegetables being planted.

In addition to being more winter harvest savvy, we now have a great tool for starting seed: The Soil Block. This amazing piece of metal makes 2″ square blocks with a nice little hole on top in which to place your seed of choice.

To make the soil blocks, you need to make a soil block mixture. Our recipe is as follows:

  • 3 parts compost
  • 3 parts soil (from the garden)
  • 4 parts potting soil
  • a sprinkle of limestone (~1/4 c.)
  • 2 parts warm water

To successfully make soil blocks, follow these easy steps.

Mix all your ingredients in a bucket.

Make a rectangular mound.

Push down on the mound, then press down on the handle to make a hole on top.

And there you have it, four seed blocks.

A perfect fit. The last step is to cover the hole with your already made soil mixture.

Benefits of seed blocking are endless. The seedlings will experience less transplant shock and will grow roots more rapidly. You want a seed block now, don’t you?
