Canna lilies will not grow

I have been growing canna lilies in the same spot with full sun for many years and have had good results. I live about 25 miles south of San Francisco in a fairly cool climate. But for the past two years, the cannas have hardly grown at all, and I have had almost no blooms. They have not died, but they just sit there. They get watered and fertilized fairly regularly, the same way I have been doing it for years.

Any ideas why they are not growing and what I can do to fix it?

Thank you….
Dave C.

Regular watering and applying a thin layer of hardwood mulch can help with moisture control, especially in warmer climates.
You mention fertilizer; You can use a light balanced fertilizer once a month during the growing season, starting right before the flowers bloom. Over fertilizing or using too high of a nitrogen formulation will actually inhibit flowering.

You can have a soil test done to determine the soil nutrients and determine if you need further soil amending.
