After the first frost came, what effect did it have on apples?

It will make the apple dull and dark red, but it will be sweet after the first frost.

The first frost, one of the 24 solar terms, is around 65438+1October 23rd every year. The first frost solar term means that the weather is getting colder and the first frost appears. It is the last solar term in autumn, which also means that winter is about to begin. Health care is particularly important in the first frost season.
