apple and pear problems
1. We have two apple trees and the fruit looks normal until you cut it in half and the center is rotten. The trees are organic and have not been sprayed. Causes and corrections? 2. One pear tree. The fruit is misshapen and as with the apples, when cut in half the center is rotten. Again no spraying. Causes and corrections?

There is a condition called apple (pear) core browning that occurs after the fruit is picked. It has to do with CO2 buildup in the storage area. Here is a link to a fact sheet from the University of California at Davis, Apple:Internal Browning. I wasn't able to find a disease that would leave the exterior unmarked, That suggested the possibility of it occurring after the fruit has been picked.
