How to Make Soil Blocks
"This time of year, we are planting so many seeds in the greenhouse. I love to use a soil-blocker tool to make blocks of soil, which can go directly into the ground at planting time." - Martha

- For her soil-blocker tool, Martha uses Soil Block Makers (from $28 each, johnnyseeds.com).
Moisten a soil-less mix that’s made for seed starting, then pack it into the soil-blocker tool.
Carefully push out the blocks into a tray. The blockers have small dibbles attached. Use them to make a small indentation in each block for placing the seed.
Cover the seed with a thin layer of soil-less mix and water.
Plant the blocks directly into the earth when they’re ready -- no need for extra pots.
