Hello guys,

I've been trying to germinate some seeds for more than 8 months with no results and I need help and assistance at this point.. Here is what I've done:

First try: Seeds on a thermo with warm water for 48 hrs.. 8 months later.. no results.

Second try: Same as before but with nicking.. no results..

Third try: Stratification implemented for 2 months on the freezer.. no results..

Forth try: 2 months on the freezer, 2 weeks room temperature, seed sanded down about 1/4 inch, will be in warm water in the next 48 hrs.. I don't know if it will work..

Am I doing something wrong?? Nothing works.

I am trying to germinate Byrsonima Crassifolia, also known as Nance/Nanche/Crabo. Its a tropical tree, the seed is around 1/2 in. in diameter, very hard and very thick. I opened the one I used on my first try and the shell is impressively dense and so thick, around 4 mm thick all directions. I had to use sand paper with 100 grain to get to the core, while sanding non stop for 10 minutes. The core, compared to the seed, its 1/8 size.

Any help is welcome!

And thanks for reading! :D
