Donna you said something I did not understand.  Can you please explain what 
you mean by DMSO on peach buds to keep them from freezing.
    Recently there was a letter about AGRO-K sprayed on peach buds to keep 
buds from frost damage.  I could not find a supply source in Northeast 
Wisconsin so I E-mailed AGRO-K in Minneapolis Minnesota and yesterday I 
received a packet that explains their products.  There is not a supply in 
this area, they explained if spayed 24 hours prior to a frost it is 
possible to have about 5F degrees of protection.  They will UPS the 
material to you.  There was not a good explanation of how  and what spray 
would be used for disease or bugs.
  As far as hardy plums I thought there are some European plums that are 
cold hardy to -40F.  Perhaps some one further north could expound on 
that.  Ray  Zone 4-5 On the shore of Lake Michigan.
