There are many benefits to soil blocking: no need for flimsy plastic cell trays that don’t last more than a couple of seasons, saves a lot of space especially if using the mini blocker, and prevents root bounding.

Soil blocking is not hard. There are many opinions about the recipe to use for soil blocking. I’ve tried a few of the popular ones and finally stopped using those because it was too complicated and time consuming to source the various ingredients and go through the sifting process for each of the ingredients. Instead, I now use potting soil from the hardware store and sift it to cull out large bits of wood, etc. that would make it difficult to maintain the block shape.

You will find that you can use the mini blocker for almost all of your flower seeds and the medium one for seeds that are larger such as sunflower seeds.

Making the soil blocks is not hard; they key is to make sure your soil is wet enough. If your blocks are not holding together, it is because it is not wet enough or too wet. Getting the feel for the right consistency takes practice, but it won’t take long before you get the hang of it.
