Don’t grow transplants in those cheap plastic pots (the ones that crackle between your fingers with the slightest bit of pressure) and then throw away the pots when you’ve moved the plants to their permanent bed. Peel Away Pots sounds like a great solution to the trash problem caused by plant pots, and they may strengthen your transplants.
I wish I still had a garden so that I could try them.
They’re not plastic-free, but they’re reusable, so they are a lot better than single-use pots.
If you have some of the plastic pots in your garage, see if a local garden center will take them back. That’s becoming more common these days.
