Soil Blockers
What Is Soil Blocking?
Soil blocking is a method of propagating seedlings that involves filling a metal blocking tool with soil and squeezing it to form a compressed cube.
Seeds are planted directly into the formed block, which can come in various sizes. This method is advantageous for air pruning roots, which occurs when the root systems start to grow toward the drier soil and air surrounding the outer layer of the block.
