We have three cooking apple trees, all 70 to 80 years old. I was always told they were Bramleys, but the fruits on each are clearly different from each other. I was wondering if you could help me to identify them from the photo. Left to right, 2 apples per tree. Tree 1, all the fruits are deep red, most are quite small. Tree 2, green with most having reddish stripes, tend to be large, some are huge. Tree 3 yellowish-green with few if any having red in them, medium in size.
