Q.Dividing Calla Lilies
I have several different colors of calla lillies in my west flower bed which are blooming beautifully. However they are getting clumped together. Should I divide them? If so, how and will it affect the vibrant colors.

You should, really, only divide them when they are on the decline. If they start failing to flower, then it will be time to divide. This will be done in the spring, after frost has passed, or in autumn. This article will help you to do so:
