I have had Acanthus mollis for 12 years or more. This year it's going to be brilliant for only the 2nd or 3rd time in all those years.
I threatened it last year, all mildewed leaves and no flowers. It must have listened. I would cut back on the TLC, especially any involving nitrogen.
It's hard to move, you get acanthus in both sites
