I did the toilet paper pots last year (below). These started out well but after a few weeks they started getting moldy or just simply fell apart. I'm hoping that using soil-less plugs will help dissuade the mold problem as well as make it easier to tell when it is time to move them to a bigger pot or the ground. I also ordered some Cowpots to try those this year as well!
Good to know I have about 2 weeks max on those toilet paper pots before they fall apart. That's why I am also trying out some plastic pot options this year.
One of my favorite methods is using a soil blocker...


Last year I bought one from Amazon, but it did not push out the blocks very well and I only got an average of one good block at a time, having to redo the other 3 blocks. Too much work. So, I complained to the selller and they determined that my device was defective and sent me out another soil blocker. But the second soil blocker was just as bad. I think they either made it cheaply or the design was bad. I sent it back for a refund.
However, the first "defective" soil blocker was still in my garage. I played around with it later in the summer and with the help of some different nuts and bolts from the hardware store, I got it working pretty well. Unfortunately, by then, it was well past planting season so I never really got to use it. I hope to use it this spring.
Previously, I had made my own PVC soil blocker....
That actually works really well but only makes one round soil block at a time. I was so excited about the soil blocks concept, that I decided to order the square 4 soil blocker thinking I would really take advantage of my time and effort. The soil blocker that I bought just did not push out the blocks correctly. Might have been a cheap model, but they all look the same to me.
There is a slight learning curve on making the right consistency of mix so the soil blocks form well and stay together. I had to make the soil mix much wetter than I expected. After a short time, you get the hang of it. Anyway, I hope to use my 4 square soil blocker this year as well as some of the other pots I am trying out.
