pink canna that won’t flower

Question

I have a pink canna that won’t flower. The foliage is healthy but it hasn’t flowered for about 3 years. I have other colors and never have a problem, as they flower every year, but for some reason the pink one won’t. What can I do to get it to flower?

Thanks

Answer 1

You could have to much Nitrogen in the soil. This would result in lush greens and no flowers.
You can increase Phosphorous by adding Bone Meal.
