Answer: If your plants are bareroot, you can plant them in the ground now. Colorado State University has a publication (#1207) that discusses raspberry culture and you might find it helpful. http://www.ext.colostate.edu/Ptlk/1207.html
I cannot find a similar publication for blackberries so they either won't grow well, or they are so easy to grow the university decided there was no reason to write a publication! Contact Colorado State University Cooperative Extension, 888 E. Iliff Avenue, Denver 80210 (720) 913-5270.
