Shemitah

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 take them and juice them? If so, what do I do with the peels? I don't have enough room in my shemitah bin.

I have strawberries in my garden that I planted during the sixth year. What is their status now that shemitah is over? If I pick them after Rosh Hashanah, do they have kedushat shevi'it? Do I have to separate terumot and ma'aserot?

On the calendars you wrote that the bi'ur time for apricots is early September (mid-Elul), but the apricot season was over several months ago. It began around Pesach time (April) and was over around Sivan-Tammuz (July). Why is bi'ur only in early September?

I heard that if grains are harvested before being edible or before the grain reaches a third of its development, they do not have kedushat shevi'it and shemitah laws don't apply to it. Since wheatgrass juice is consumed, does that change things? Is there an issue of sefichin?
Any other considerations or special laws?

Hi, I was given a gift of wild sumac. I don't know if it's primarily used in food or medicine in Israel.  Is it sefichin, and does it have kedushah? I have no idea what to do with it but I'll offer to anyone who wants if I know its status.

I just bought my first shemitah mangoes. What do I do with the peels and pits?

I have an established eggplant planted in my back yard well before shetmiah. During the winter it was dormant, and now it is beginning to wake up and produce eggplants. I looked up on the sefichin calendar and it says that eggplants are sefichin starting November this year (Kislev).

I'm confused, though. I thought that plants that behave like perrenials are not sefichin and, anyway, I planted it before shemitah. What is the status of the eggplants?

Our pomegranate tree is blocking part of the staircase. The pomegranates aren't completely ripe yet. On the same branch there are fruits of different sizes and stages of ripeness. It is a real nuisance. Am I allowed to prune the branches?

How can I prepare Shemitah wine at home?
