1. Growing Green Onions in an Egg Carton

Tools You’ll Need:

  • 3 cardboard egg cartons
  • 1 plastic bag

Steps to Grow Green Onions:

Take your three egg cartons and cover one of them with the plastic bag. Stack the other two cartons on top, ensuring they fit snugly together. This will serve as your mini greenhouse for the green onions.

Step 2 Plant the Shallot Bulbs

Gently place each shallot bulb into an individual cup of the egg carton. Fill the cups with water until it reaches halfway up the bulbs. Ensure the root end is pointing down and the sprout end is facing upward. This will encourage healthy root growth.

Note: Always position the bulbs with the root end down for optimal growth.
