Friday Favorite: Soil Blocks

June 5th, 2015

This is the first year I’ve used lots of soil blocks in my seed starting and I LOVE them. The seedlings definitely grow better and have much less transplants shock. There is a bit of a learning curve to making and managing them, but one you get it they’re perfect. Yesterday, I got four more flats of summer lettuce and other fall crops going in soil blocks.

I’ll definitely do a long article or a series about them here when I have time to sit down and write it. They are well worth the investment in time and money.

Have you ever used soil blocks?

    I’m really looking forward to your full post on this topic. I own two different size soil blockers that I bought from Johnny’s and I’ve never been able to get them to work right.

    For one, I think the soil mix has to be just the right consistency and I’m too cheap to mail-order bags of the Johnny’s mix, so I keep trying variations on your vermiculite-based mix (when I can actually find vermiculite locally). I’ve also tried some store-bought starter mix. Then, getting it just wet enough but not so wet that it sticks to the blockers is also difficult. Then, I always have problems keeping the moisture even and watering and I’m never quite sure how to space the blocks. Half the time, I go to water the tray and the blocks disintegrate. I also find that it uses 3x as much soil mix as plastic cell trays, which can get pretty pricey when you do a lot of trays.

    So yeah…I’m looking forward to your post. :-)

    I have never used soil blocks but I remember my dad using them. I have seen a few articles on them recently and have been considering picking up a blocker to try.

    Susy, yup, I’m with everyone else. I didn’t get them to hold together and found them disintegrating when watering time came. I just use the small fiber square pots to start plants and then pot them into plastic drinking cups with holes drilled in the bottom. I know the instructions for the fiber pots say that you can just plant the whole thing in the ground but I pull it off when I re pot into the bigger plastic cups. It works for me. The potting soil and the moisture content is not a worry when I do it that way.

    Have a great soil block day.
