Method

First step in growing Tropical Canna’s from a seed involves chipping the seed.  Canna seeds have a very hard coating which wears down over time in a moist environment.  If you simply planted the seeds, whole, germination will be more unpredictable.  By chipping the seed you are in control of timings.

A certain amount of pressure needs to be applied to scratch the seed coating. Don’t go too deep, just until you can see the white inside.

This may take a little practice.  The seeds have a tendency to slip off  fingers and all over the place.
