Is your bulb looking a little spent? With all the pressure of a flower show, he may be a little weary. If he is still strong and perky he may have a friend in the pharmo/fert industry. Good on him!
One day soon, if he has not already, he will yellow and grow weary. Brace yourself, Lorena: chop it off.
Remove the spent foliage, lift the bulb from the soil, and put it in a dry place in your cellar or garage. Note: It must not freeze, nor may it remain too warm. The 40 - 50 range is about right.
In the spring you may repot him and look forward to another interesting season. More will be revealed…
