I have a nice big healthy spathiphyllum (peace lily) growing indoors.
I've had it for almost a year and this year there are 6 flowers (or
spathes to use the correct term) growing on it. Some of these flowers
are almost mature and some have just begun to grow. But the mature
flowers are much smaller than the flowers it had last autumn when there
were only about 2 flowers.

My question is: Is this because the plant is investing so much energy
in growing 6 spathes that it has to keep them small in size? If I had
snipped perhaps 3 of the flowers when i saw them begin to grow, would
the remaining flowers have grown bigger and taller? Or is it a bad idea
to cut growing flowers on a spath?

Thanks for any help
