As a free gift with one of my tropical fruit trees, I got recently, I was sent a mini zipper bag of 4 CHERIMOYA seeds. Online, there are videos, that discuss first soaking the seeds, before planting, and tossing any seeds that float to the top, because they are non-viable. Before soaking the seeds, I rubbed each seed across some coarse sandpaper, in order to create a tiny opening for water to enter the seeds. However, after scarifying the seeds, ALL floated to the top. At first, I thought I had only been sent some "old, dry" seeds, as a way for the vendor to get rid of them, because, even after a day of soaking, all the seeds were still floating on top of the water. I sowed them, nevertheless, expecting none to germinate. Cherimoya seeds usually germinate within a 10-60 day window. After about 30 days, ALL FOUR seeds germinated. The first one, after about 18 days. Here they are after about 40 days. They will soon need to be given individual pots. Cherimoyas can begin fruiting in about 3 yrs, from seed, and can do so in a container, for folks in the North, like me..

Alvin, nice scoring those a Cherimoya seeds. It is fun to germinate seed. . I still have Dorothy’s Surprise Camellia japonica blooming. If we get temps I. Twenties in a few days it will take care of any late bloom.
I always drop seeds in tepid water for a few days before planting, I discard the floaters. In nature, birds eat the seeds, they then are warmed in their stomachs, softened up and then get dropped complete with natural fertilizer
Yeah, I was pleasantly surprised that the Cherimoya seeds germinated, after floating in the water, after 24 hrs. Good thing I tried planting them, and NOT toss them, as I was advised to do. Online gardening advice can be inaccurate, or not given by experienced gardeners, sometimes. Some of Dorothy's Surprise blooms could be damaged by mid 20s. Unopened buds will open when temps moderate, your way.
Nick, this experience taught me that even "floaters", can still be viable. There is a difference, too, that needs to be pointed out. The Cherimoya seeds that were soaked, and floaters tossed, in the video, had just been removed from fresh fruits. Dry seeds from some tropical fruits are assumed to lose viability, in days, rather than months or years, as is the case with many types of seed. My Cherimoya seeds were dry, and on hand, with me, for a few months. No telling how long they were with the gifters, before that.
