Moisten the mixture enough, so it sticks together without water dripping out. Write the name of the seeds on the bag. Place the mixture in your refrigerator for 30 days. Seeds can then be sown into a well-drained, sandy compost and covered lightly with sand or grit. Place the seed tray in filtered bright light and keep moist until germination.
