I recently enjoyed fresh starfruit for the first time. I managed to save some seeds when I was slicing the fruits. I noticed the seeds had a "slime" coating on them. Do I need to let them ferment like tomatoes? Or rinse well and let them dry?
To the best of my knowledge, Averrhoa carambola seeds lose viability within just a few days of being removed from the fruit. :-? So I don't think it's realistic to "save" the seed, just go ahead and sow it if you want to grow a tree. I understand that they can grow quickly enough to produce a few fruit within 4-5 years. ***Edit to add: There is a lot of good info HERE including this:
