What causes the pits/knots in my pears that makes them inedible?
Last year many of our pear trees (we have about 10 varieties) had fruits with pits or knots in them making lots of the fruits nearly inedible. What causes this, and is there anything I can do to correct it?
I always prune my trees in the same way, and also thin the fruitlets early on. Do not fertilize or spray, other than applying ramial mulch around the base.
I’m sorry to hear about your pear woes.
That said, similar symptoms can be caused by insect damage and boron damage, but we would need to submit a sample of the fruit to the UMaine diagnostic lab in order to be certain–unless it’s clear to you from the above resources that we have the diagnosis correct, I recommend getting back in touch with us next season when we can get an analysis performed for you.
I’m sorry not to have better news for you, but I wish you the best of luck with your other pear trees.
