cotter pin, I'm surprised to hear you are growing the Noir of Spain from seeds. You must have a lot of patience to try to grow out the seeds and wait for it to fruit.
Isn't it much easier to just graft a cutting, then you will have fruits in 2 years. How old is your white pakistan and red himalayan tree/plant? If your everbearing tree is large enough you should graft a few white pakistan and red himalayan scionwood that was cut from a fruiting tree. If you don't know if your trees have fruited before, send me a PM and I have large fruiting white pakistan and red himalayan trees and I will give you a good deal for some cuttings.
When I purchased the seeds at a seed exchange, I was thinking 5 years to fruit, but the more I read into them, I now know they they may take up to 10 years. They are still too small to use as a scion/bud wood for grafting at this point. I purchased the red Pakistan about a year ago it was about 5' tall in a 3 gallon pot and put it into the ground right after I purchased it and it is about 8-9' tall now. And, the white Pakistani and Tice I just purchased and put into the ground about 3 months ago. I have actually eaten fruits of of the Tice, only a few... but it's pushing fruits.
I do not know much about grafting mulberries at this point, but if I need some cuttings I will defiantly be in touch with you. Those Thai Dwarf's are off the chain crazy with production! Looking good!
