I'm going to try to plant some erect blackberry seeds which I picked. I have a number of containers with seeds and peat moss in the refrigerator at 34 degrees that I have treated differently to see which might grow if any.

1. Battery acid
A. 1.5 hr
B. 3 hr
2. Nipped with nail clipper
3. Sanded with fine grit sand paper
4. Natural (nothing done to the seed)
5. All of the above (1-4) but will leave out side for 7 weeks in peat moss. Then refrigerate for 500 chill hours.

My question is - Most information I've seen on line says to refrigerate for 3 months then plant. If my blackberry requires 500 chill hours would I not take the seeds out after 21 day in the frig at 34 degrees? Will they spout in the frig?
