Everyone else seems to have folded up for the night so I'll have a whack
at this. I live in very cold Zone 4, have many TB's that have been
planted/transplanted within the last month & some have definitely sent
up new leaves in that time -- but I'm not doing anything "special" for
them even tho it's been at or near freezing every night for the past 5
nights here. (It snowed 3"-4" Sat. night.)
This may seem foolish to you but I've never had any problem in the past
-- it may delay bloom for a season on those that are *really* new in the
ground but that's okay with me. Normally, I don't put in any bearded
iris later than mid-August but this has been an unusual year, not just
weather-wise (Aug. was soaking wet, for one thing) but also because I
started a whole new bed just for iris this year & it took awhile to
accumulate enough rhizomes to more-or-less fill it.
Anyway, I'm not planning on covering or mulching unless someone more
experienced on the List shouts at me! If you're worried that your
newbies will suffer a set-back, you could certainly mulch the beds with
straw or pine needles or dry leaves, whatever you have. Just be sure to
get that cleaned out before the temps start really warming up in the
spring or you may have a lot of rot &/or borers to contend with.
Hope this helps some.
