Postal Petalsâ„¢ is a complete flower garden that features fun facts on the back. You can mail it just like it is. Standing approximately 8.5" tall and 5" wide, this exclusive garden kit contains a natural growing medium and select seeds. Just water the seeds and potting mix that are inside the leak-proof bag it comes in, add water and sunlight â€“ and enjoy. It grows right inside the bagâ€”no waste. No fuss. We suggest making a few small drain holes at the bottom of the bags to encourage maximum drainage to ensure a healthy garden.
