Part 1 of the question:
I have an iris that I'm thinking may be on its LAST year. The reason I think that is because there is just ONE rhizome left and that rhizome has a bloom stalk on it. Is it still possible that it will form increases (none are showing at this time). It has its last bloom on it right now. I will be cutting the stalk off soon. I always cut right down to the rhizome or about 1/2" above. Since I see no increases, should I leave more of the stalk on or does that not matter?
(Crazy for You) This is the one I'm referring to. I like it a lot and hate to loose it.
Part 2 of the question:
When dividing iris, if an increase is of decent size, should I cut the increase away from the rhizome that has bloomed?
If so, what is considered a decent size.
If they are pretty small, is it best to leave the "mom" rhizome attached to the increase?
