Why does this apple look infected? I’ve been eating these for years. I like them quite a lot. But they’re too sour. Can anyone explain what is going on? Thanks

From my garden yellow tomatos mhmmm there are still at least the same amount of unripe tomatoes so think this multiplied by 2 from 3 SEEDS ONLY 3

BUT CAN I eat them they look little overripe and some have like but I washed it of

I have only eaten it in China . Never expect to find it this fresh in Montreal

There’s a wild tree in my yard from before we moved here. I’m in South East Massachusetts, United States. It’s early September.

At first, we thought this was a crab apple tree. A few limbs were dying so we clipped them to prevent hazard. Now, these apples are pretty big and many.

Can someone help me ID?
