Soil-Block Makers | Instructions & Blocking Mix Recipe | Tech Sheet (PDF)
Follow these instructions with your Johnny's soil-block makers for best success, creating blocks of growing medium that have been lightly compressed, so they maintain their shape without the need for plastic containers. As your seedlings grow, their roots reach the edges of the soil block and are air-pruned by the separation between the blocks while increasing the oxygen available to the roots, which can increase vigor. This gives seedlings a substantial advantage when transplanted into the field — reduced root-disruption makes them less prone to transplant shock. Read More
