Emerging root from a soaked Canna seed
After a couple of days in soak, they need to be planted. They can either be planted in individual cells trays or in 3 – 4 inch flower pots. Using individual seed trays removes the need to prick the seeds out. Untangle all their roots and plant individually when they are a bit older. However the germination success rate seems to suffer. So if you only have a limited amount of seeds I would plant them in plastic flower pots. I would also only plant a maximum of 4 or 5 to a pot. This is to reduce the headache of untangling the plants when they need their own pots.
