I'm no expert, but here is what I have done... and it's been pretty successful overall.
The first thing is to pick a variety that goes with your zone. Cold loving or warm loving or whatever.
I picked a spot and mowed it short. I rototilled up a strip as deep as I could go. The first time I just added about 3-4 inches of
compost. I planted the bushes about 12" apart and kept things mowed nearby and weeded while they were establishing. Also
water... lots of water as raspberries have shallow
roots. Those were doing great, but we had to move. The next time I put down some compost, then some
newspaper as mulch with about 2-3 inches of woodchips on top. Way less weeding and they were looking great for the first season, and I had to move again.
I also expirimented with growing garlic next to the row. The garlic grew just fine, but I don't know if it helped with any pests.
