Gavin, hi. My friend Linda uses Poast over her TBs with no apparent ill
effects. I haven't used it, preferring as I do to yank weeds rather than
zap them whenever possible. You can get long-lasting control using
solarization, which can be conveniently done at division time.
Are you staring at a very large overgrown bed? In such cases, the plants
are often in need of transplantation and thinning. If the area's too large
and overgrown to hand-weed, I would Poast the grass while it's actively
growing, with the thought that you will dig out all your irises, thin them
and solarize next summer.
