Today I made 4 flats of soil blocks and started the 2017 onion crop. I used soil from my garden that has been in the storage barn (a re-purposed car port), some peat moss that has also been stored in there, and added some compost my husband picked up for me at Agway. Not sure how nice that dirt is that has been stored, and it never hurts to add more humus. I also put some Epsom salts in there because our soil here seems to like the addition magnesium, or at least the crops that grow in it do. The soil to peat moss was about 50/50 (guessing) and I put 2 buckets of that mixture with 1 bucket of compost mixture and about 1 cup of Epsom salts. Then I added the same size bucket of very warm water and just let it all sit for a few minutes. So that is my process for today- not very scientific. I put about 4 seeds in each soil block. This year, I am trying 2 new-to-me onions- Talon, a hybrid yellow onion, and Redwing, another hybrid onion that is red. I planted 85 blocks of Redwing. 95 blocks of Talon. And 6 blocks of Prince, the variety I grew last year.
