Create the Grass: Cut green construction paper into strips the length of your egg carton and about 3 inches high. Then, cut triangles out of the top edge of these strips to mimic grass.
Make the Flowers: Cut out various flower shapes from the colored construction paper. Also, cut out small circles from any color of paper to serve as the centers of the flowers.
Assemble the Garden: Use glue or a glue gun to attach the grass strip around the outside of the egg carton. For the inside, cut the grass strips into smaller pieces and glue them into each compartment of the carton.
Add the Flowers: Glue the small circles to the center of each flower. Then, arrange and glue the flowers onto the tops of the grass around the egg carton, both inside and out.
Place the Easter Eggs: Nestle your decorated Easter eggs among the flowers inside the carton to complete your garden.
