Re: Scarifying seeds?
This is my experience. Some seeds beneift and some don't. If you don't chip canna seeds you will wait much longer, if you even get any germinaton. I have found Ensete seeds seemed to respond well to having been roughed up with sand paper. Musa on the other hand had no response to nicking etc.
Ultimatley the best thinsg for germination are freshness and heat.
Jim can you tell me more about your use of epsom salts with seeds?
