my gladiolus have been in a container for over two months sunny position, plenty of good leaf growth but no sign of flowers! can
not understand what is wrong!! would a feed of blood and bone help?
First, I wouldn't panic. Glads don't bloom in cool weather; mid to late summer is their time to shine. Here is an article that lists reasons for non-blooming. Yours appear to be healthy so ignore comments about rot. One caution: too much nitrogen causes lots of leafy growth at the expense of flowers. If you are using a long-acting fertilizer, additional bone meal, etc is not likely to be helpful. Glads are not "heavy feeders". https://www.gardeningknowhow.com/ornamental/bulbs/gladiola/getting-gladiolus-to-bloom.htm
