If you're not seeing anything yet, I assume you planted
seeds? Or did you buy plants? I'm not familiar with
growing raspberries but I have blackberries. I'm in
zone 8 and mine just got leafed out good in the last couple of weeks so yours are probably just not ready to come up yet. BTW, mine didn't go into the greatest soil either (clay) but I put a layer of compost around them each
spring before mulching real good with wheat straw and they are doing real good.
