Is it normal for iris to fall over? I mean the flowers, of course. They

Should I tie them up somehow? The flowers are HUGE.


If these are bearded iris, the stalks may have been chewed by
snails or slugs. In my garden, that is the usual cause for iris
stalks to topple.


Insufficient watering may make the stems weak. It's internal water
pressure that stiffens them. (Also happens with amaryllis, for example.)
