Thanks for the replies. I thought as much, as the ones she used to buy had to sit in the bowl a week before they were fit to eat.
My first serious pear harvest, trees have been in the orchard garden 5 years and are a bit tall and full of fruit. Not bad for some of Woolies 99p bargains. It looks like I will be busy for a couple of hours.
When they were younger and only put out a few fruits, I let them drop and stay on the grass. I had a lot of trouble with my dog who took a liking to them and they really upset his tummy. Had me and the vet puzzled for a while, untill I caught him eating them.
