I knew older rhizomes died away, but I did not know that they start to die after blooming only once.

Thanks.

Coming late to this party, but THANKS! I have some ever expanding drifts of irises that need attention, and digging and dividing was not something that I wanted to do. (One woman (with limited garden help), large garden, prone to migraines in the heat....when the irises need dividing.)

And curiously enough, cleaning up my shed I recently came across a still-in-the-package hori hori knife, which I had bought some time ago...and couldn't remember why I had bought it. Now I've got a definite use for it!

Excellent!

Also one woman here, no help save the neighbor who "lifts and carries" for me twice a year. Small garden - city sized lot, no migraines but prone to heat stroke in July/August.

I love wrestling with everything myself - but SLOWLY! When I get it wrangled into shape that I only need maintenance, I'll know I did it ALL my own damn self! I will like the knifing better than the digging, though.

Gotta get me a hori hori.
