Vermiculite tends to retain water. Soil, bark, perilite is what I use to make a fast draining mix. Did you give it a cold period to make sure the bloom elongated? That would be my best suggestion. And when you repot it will give you a chance to look at the roots. Hope that helps!!

A cold period, No I understood one just quit watering for a month, How cold and for how long??? Thanks for reply...Jack

Standard advice is to give clivias 6-8 weeks of temperatures under 50F in the fall along with little or no water or food for about three months. They do not need to be in low light or pot bound to bloom. This assumes you have fertilized regularly for the other nine months of the year. Use a fertilizer with a 3-1-2 ratio and all minors. I have some variegated Chinese daruma clivias that bloom regularly without a temperature change or a dry period and some other clivias that clearly need both.
