What You'll Need

It's seed starting season. Yea!! You can start seeds in a variety of containers. People use everything from empty egg shells to the plastic six packs last year's plants came in to just about any container laying around. There comes a point at the beginning of the season when you have a lot of plants going and containers can get scarce.

Imagine if you didn't have to deal with storing mounds of little plastic pots and just did away with containers altogether! Well you can, and the answer to your prayers is the soil blocker. It compresses soil into...well...blocks.

Now, you can buy a soil block maker. They cost about 30 bucks from Johnny's Seeds, but what's the fun in that? I decided to make my own. You can too. It's not that hard.

Here's what you'll need:


  • About 2 feet of pine board 3/4" thick x 2" wide
  • An 8" piece of 4x4
  • About 2 feet of aluminum plate 1/8" thick x 2 3/8" wide
  • 12 wood screws
  • 1- 3/8" carriage bolt 4" long
  • 1- 3/8" nut & washer
  • Clear acrylic or varnish


  • Drill and bits
  • Table saw
  • Thin file
  • 3/8" tap
