I usually just use a shovel and cut the center of the clump in half. Dig up
one side and get rid of it by giving it away or transplanting it. The other
half of the clump will usually bloom the following year, if I didn't disturb
it too much while removing the other half. If your clump is too big, you
will have to remove more than half.

I have two or maybe three varieties. One clumps, (Looks like a plain
old flag lily or bearded iris, but will tolerate wet feet.) and one
variety the rhizome divides and produces two new one's and the rhizome
that bloomed becomes bug fodder. These work best to divide every year
and bloom early every spring. The third variety blooms more than once
a year and someone else dug them for me last and I just found two of
them last month when they bloomed. I've never had a year without a
few blooms.
