Raspberries do best in a clay type of soil. Clay loam is fine and is the basic type of soil that is native to them.
The black types seem to take up a little more room, but not so much that you need to plan on a great deal more space for them.
Raspberries reproduce by their canes which droop over allowing the tip to touch the ground. At that point of touching the ground the cane will root and produce another plant. You can help this happening if you like by getting a cane to lie on the ground, putting a weight, like a rock, over a spot on the can and mounding up soil. The cane will root whether there is soil in contact with it. The rock in this case would only be used to steady the cane so it doesn’t spring up and lose contact with the ground.
Orange rust is a raspberry problem and the best route is to just destroy affected plants. Don’t compost the canes, just let them go in the trash.
The raspberry borer is a small beetle which will bore into the canes’ summer growth. It is fatal.
Cut worms can get at the young plants and wreak havoc. All the standard methods of dealing with these issues will work just as well on raspberries.

Red Raspberry Tea
Use the leaves fresh or dried for raspberry tea. When drying slightly crumble the leaves and use a tea ball in hot water. Fresh leaves should be bruised slightly and then inserted into a tea ball. You’ll need more leaves when using fresh than when dried.
