Homemade seed mix

At the beginning of February, I did some research and decided to make my own seed mix this year. I normally use a soil blocker. The soil blocker takes a ton of soil since it compacts it into squares. I plan on making some this week since I need to start my broccoli and spinach seeds. So having my own mix will save lots of money.

However, for the onion seeds, I didn't bother with the soil blocker and put them into a tray. The soil will be dumped later on and they will be individually planted so no need to mess with the blocker for them. The onions were a good test to see if the mix worked.

I stayed with a sterile mixture, no compost or soil.
3 gallons peat moss (bought in a big square at lowes)
about a half gallon of vermiculite
2 Tablespoons limestone

So far so good!


I think I may need to add some kind of fertilizer once they get bigger.
