Beit Midrash

I have citruses on my tree that began to develop last year (5782), so I know they have kedushat shevi'it. But are they still hefker, even though it's the 8th year now? In other words: does hefker follow the status of the fruit or the year?

I see bananas in Otzar Ha'aretz stores labeled sheminit, eighth-year, at the end of Tishrei. How can that be?

We are now in the asseret yemei teshuvah 5783. I walked down the street and saw many pruned branches with tangerines, most of them ripe and some partially ripe.Do these tangerines have kedushat shevi'it?Is it permissible for gardeners to prune them?   Am I allowed to...
