Re: Irisborers (not Kathy)


Rich -- among the other suggestions you will get might be one to completely
remove the existing soil, sterilize it to get rid of borer larvae in dormancy
(or whatever you call it when they are cacooning down in the soil) and
put in new soil -- at this time of year, they are ready to come out of the
soil and become moths and start laying eggs.

OR__ move the bed... put the iris where no iris has gone before -- 
which kind are you putting in? bearded or beardless??

Carolyn Schaffner in Buffalo, NY who knows a local grower who removes the
soil where he is going to plant new T.B's and puts in bags of soil from a
nursery and swears he has no borers!!
