[OPEN] Plant not planting

I have the same issue, my apples and pomegranates are giving me the "failed to germinate" message, when i plant them in a garden planter. I'm trying to plant them sheltered. The apple was bought from grocery service and has been in the fridge before i tried planting it, and the pomegranate was harvested from my own grafted plant and has not been in the fridge, just in my inventory after harvesting. I tried the workaround with moving it into the household inventory, but it didn't work. I tried it several times, always slightly differently, but no try worked. I also tried hiring a gardener, but even the gardener didn't succeed. There is only one way that finally worked for me after lots of different tries: When I plant the fruit outside (non-sheltered), I planted them in the fields that are made for the oversized crops, they finally germinated, and then i went into build mode and moved that pile of dirt with the germinated plant in it to my sheltered garden planter. It then stayed in this state and started growing.
