Raspberries!

I know nothing about growing raspberries, but I will plant a couple of varieties tomorrow. I'm not sure which varieties I have and I don't want to go out in the rain to see which I have. All I know is one variety is red and the other is black.

Can I expect to see a few berries the first season? I've grown so many different things over the years, it is my habit to plant in a 50/50 mix of sandy soil and organics. I will probably plant the raspberries the same way. Is that okay?

Since we get so hot and dry in mid summer, I usually make my planting hole eighteen inches in diameter and sixteen inches deep. The loose soil and organic mix helps to retain moisture between waterings.

Suggestions will be appreciated.
