Okay! I came across this easy to follow tutorial for repurposing a 2 liter bottle for use as a green onion planter. It looks like a money saving way to have a steady supply of green onion tops for all the tasty Whole30 meals I’ll be cooking. The seed order is going in this week, so I’d like to try growing some onions from seed and planting them this way when the shoots are strong. Has anyone done this?
