Love the apple pips/seeds success, we succeeded with plum stones/seeds last year, as you say Lou process of firstly drying them of the flesh/fruit, then place the stones/seeds in a damp paper towel in a plastic bag into the fridge…
After a while they sprouted, then transferred into a pot, grew about 20cm, and died off, however its spouted leaves over these past weeks and looks great.
I’ll get some pics tomorrow to show ??.
