Thank you for your quick reply, everyone! @bleedingdirt,@marknmt, @Steve333,@growjimgrow, @clarkinks
I was busy yesterday afternoon. So the first chance I got after everyone confirmed it’s fire blight, I went out prune off the affected branches.
This is what I did: I found a really old pruner and dipped it into 30% diluted bleach (30% Clorox bleach, 70% water) after each cut. Most of time I pruned off more than 1 foot from the blacken area. I double bagged the diseased branches with trash bag, they are in the garbage pick up truck somewhere now.
Now I can only hope this is good enough.
While hubby and I were pruning, I realized there were a lot more affected branches than the 4-5 branches I originally thought. Don’t know why I didn’t notice them sooner. Now most of fruitlets are gone, and the tree is a lot shorter.
@clarkinks I already pruned off the branches when I saw your post about break it off instead Do you think I should go back try to break them again? Thank you for explaining how a tree get affected by the bacteria, I was wondering about that. So, if pollinators carried the disease over, there is no real way to prevent it, is there?
Just some background info: I have 2 pear trees, they were all impulse buys from big box stores 4-5 years ago. One for $5, the other $7. I just started getting into graft then, everything was a potential root stock to me😀
One tree is Ayer, and I promptly lost the tag of the other, i.e. the inflicted one. (@growjimgrow I hope this answer your question, I don’t know what it is🙂) All I know is it’s one of the popular one that suppose to cross pollinate with Ayer.
But it turns out the unknown one always flowers one week after Ayer! Since there is no pear tree nearby, every year I have to pick some flowering pear tree flower to pollinate Them by hand. If this is not bad enough, by the time the unknown tree begin to flower, most of flowering pear tree are done flowering!
I have grafted a few other pear on to these two trees a couple of years ago, hopping they can cross pollinate. So far the grafted pear branches have grown very tall, but no flower yet.
Both trees started fruiting last year, the Ayer pear was very very good! The unknow tree was not as good. It has smallish yellow pear, someone said it may be kieffer.
All my fruit trees get sprayed with copper, captan and triazicide with spreader at peach bud break, pear trees bud break is much later than the peach. So the pear trees get copper once a year before its bud break, it doesn’t seem to be enough to prevent fire blight on this tree. but, we had a very wet spring.
And whenever peach get sprayed for brown rot and bugs(captan and triazicide), I also spray the pear for good measure
So this is all the background and my practice about my pear trees, do you see anything wrong? Anything I can improve on?
