Choose a different color of origami paper to correspond to each type of seed you are planting. The idea behind making a classic origami Masu Box is that the paper planter itself stands upright easily, and the walls end up being multiple layers thick, which helps with water retention. The finished boxes should be about 1” tall, which is deep enough of a space for the seedlings to root before transplanting them into a larger container garden or into the ground.
Create the initial origami folds by creating creases on both diagonals, and then unfolding and re-folding the corners into the center. While still folded, crease all four straight outer edges into the center.
Partially unfold the paper, allowing two opposite corners to meet in the center. Fold the top and bottom edges inward to the center point, along existing crease lines.
At this point, fold to crease and unfold both ends on the diagonals. Creating these crease marks will it very easy for the walls of your Masu Box to take form.
The creases created up until this point will be guiding lines for creating the four walls of your planter box. Lift one side at a 90-degree angle, and fold it in place so that the point on the paper matches the other two points already in the center. Repeat on the other side.
Keep the seeds in a warm location, and keep the soil moist. If your house is drafty, simulate a greenhouse effect by placing the planters in a glass baking dish with a cover to help retain heat and moisture.
After a week or two, the seedlings will begin to emerge. Continue to care for them as the roots take form, and transplant them to the garden when you’re ready. If they’re going directly into the soil, use a pair of scissors to score the base of the paper box, and drop the whole unit into the ground. The paper will biodegrade over time, and you can spare the chance of damaging any of the seedlings in the transfer.
Remember to consult on guides for companion planting when you are planning your garden. These new herbs can be great complements to vegetables when planted in close proximity.
