Thanks Kathleen,

I do have a compost heap, but our growing season is so short and we have
relatively little green material, that with the dry air it can take a long
time - like years to make compost.  I have recently tried using coffee
grounds from Starbucks to see if I can speed up the process.

We do have rodents.  Yesterday I killed a gopher the size of a big Guinea
Pig.   We also have voles.  

I have never cut my Iris.  Why is it done?

Colleen wrote about irises and piling leaves on them. It's not clear what
kinds of iris you grow, probably tall bearded?

Most iris should be cut back in fall or early winter. Then, winter mulch in
dry cold climates should not be a problem, unless it gives rodents a
foraging advantage. [In wet winter areas, dense mulches like hardwood leaves
can create serious fungal problems for irises.] Don't forget to pull the
mulch back in spring. 
Do think about creating a compost area for those leaves and other suitable
garden debris.
