Do my gladioli bulbs need replacing?

My gladioli bubs have been in the ground 5-6 years now and flower beautifully every year.  Last year there were leaves but no flowers.  Not sure if this was due to lack of water during the very hot weather in June (they weren't watered as I was away), or whether they've been in the ground too long and don't last beyond a few years?
So do they need replacing or could they flower again this year?

    My gladioli also didn't flower last year, they only had a leaves. I thing that they will flower this year because they accumulated energy and feed in the bulbs. I always left me in the ground over the winter. Even now they are under snow but came out normally every year.

    It could be down to the lack of water, or possibly they need dividing. I think if they aren't divided after 4 or 5 years, because they have formed lots of corms there is not enough energy for the plants to form flowers.

    They need dividing, as AnniD say's the corms will have formed lots of smaller corms and after being in the ground for several years these clusters have become to big for the corms to produce flowers, they need separating.
      
    I lift mine in the autumn, some are a lot older than 5 or 6 yrs yet flower every year.
