Bill,

 

There is no more risk to your trees for fire blight from summer pruning than there is from pruning out fire blight in the summer.  And, once again, once the terminal buds have set, fire blight risk in minimal if not completely gone.  Hope this helps!

I think you'll be okay if you sanitize your pruners with a 10% solution of bleach between cuts. Then again, they're your trees, if you don't want to risk it, don't.

But isn't there a problem with fireblight in summer pruning apples? I've
been pruning everything else but apples and pears, because I've had
fireblight really bad on my Suncrisp apple, and I didn't want it to
spread. Unfortunately, a couple of my trees REALLY need pruning.

I must admit that I haven't notice fireblight on the Suncrisp where I
cut off infected branches (it just seems to pop up at random), but I
thought that was how it spread, through cuts (and through blossoms,
during that time of year). I've had a LOT of fireblight on the Suncrisp
(a fireblight magnet, as some of you have told me), but nothing yet on
the three trees planted only 18" away. I had a little bit, earlier in
the season, on my Pink Lady apple, but I haven't seen anything on my
European or Asian pears.

What do you think? Do I need to avoid summer pruning on all my apples
and pears, or not?

Thanks,

Bill
