Re: [nafex] fireblight resistance



Hi,

I am shocked about the Clapps.

We are much further north than you (sw Ontario) and the Clapps gets no
frost damage.

We are in Canadian hardiness zone 6a, which I think relates to zone 5 in
the U.S..  Our winters are moderated by the Great Lakes, but boy do we get
wind!

What is the difference?

Later,
Tom
