Can you include a photo? Do you mean that you cut the entire plant down to the ground, or do you mean that you had to cut a branch off? If you had to cut the whole thing down, then this can put flowering off for several years.
If it was just a branch cut, then should not stop flowering. Did you cut the stem because it was dying, or rotting? If this is the case, then there could be a fungal infection. Cutting it off will stop the spread of that particular area, but it will not kill the infection.
A photo and a little more detail will help me to pinpoint the problem.
