Soil block recipe

Thanks for your patience with this soil block recipe. I had great plans for making an infographic for this, but I’m wearing too many hats for that to become a reality, at least for this year.

If you are in Manitoba, starting a dye garden from seeds would start around mid-April. Sowing seeds earlier than that could cause your plants to be in stress before transplanting.

Mix:

10 cups potting mix

7.5 cups compost (I use seasoil brand)

1T green sand (potassium and trace mineral source. In Manitoba, I buy from Sage Garden)

1T bone meal fine (phosphorus and calcium source)

1T azomite (trace minerals; if you can’t get this, you can skip)

The mixture should be wet but not soaking, so start with 6 cups of water and add as needed.

Note:

• I always have to sift/screen the compost if I am making minis to eliminate the big chunks. For the 1.5” and 2” sizes, I don’t have to sift sometimes, but if you find that big chunks are in the way, please sift.

• For the potting mix, sifting depends on the brand I use – if the bag has bigger chips, I have to sift even if I am making minis. For the bigger soil blocks, no need to sift the potting soil.

• If you do not have the soil block molds, you can still use this recipe to fill whatever seed starting tray, pots or cell tray you have available.
