How to start seeds with the soil blocking method
Do you start seeds with the soil blocking method? I am totally hooked on this space-saving technique for seed-starting.
I even made a video to show you the process. Don’t see the video? Click here to watch.
You will need:
- Potting soil
- Soil tray (here’s another tray option)
- Soil blocking tool*
- Seed trays (another seed tray option)
- Plant markers
*Mine is a 4-block tool that creates four 2-inch blocks.
If, like me, you don’t have a greenhouse, you’ll also need:
You’ll find detailed instructions for assembling your own cost-effective shelves and lights here: Simple DIY Seed-Starting System.
Reminder: watch the entire process in my quick video demonstration.
- Add soil to the tray.
- Add water to the soil.
- Mix well, and repeat until mixture reaches the consistency of peanut butter.
- Scoop up soil with the soil blocking tool and eject soil blocks into the seed tray.
- Repeat until the tray is filled with 50 2-inch soil blocks.
- Note: Turn the soil blocking tool to fill in the fifth row of ten blocks. I recommend starting by filling only two soil block cavities in your tool and ejecting them into that last row. Then you’ll make two full scoops of four blocks for a total of ten blocks. Otherwise, it’s kind of tricky to get those last two soil blocks into the row if you’ve already added eight blocks. I hope that makes sense!
- Add seeds.
- Sprinkle a thin layer of soil over the seeds, and tamp down gently with your hand.
- Be sure to label each tray with the name of the seeds. I also like to add the start date.
- Transfer the seed trays to a greenhouse or to your indoor seed-starting shelves.
- Water frequently.
And that’s it! Learning to start seeds with the soil blocking method simplifies the seed-starting process and maximizes growing space. It’s my favorite way to start seeds, and I hope you love it too!
