My raspberry plants seem to have stunted growth. Some canes that should leaf out don't completely and the flowers don't form berries on some plants. There was possible herbicide drift about 4 years ago.
Wondering if we need to start over with new plants? If so, is the soil is a problem?

If raspberries have been grown in the patch's current location for a number of years, this excerpt from a University of Wisconsin bulletin may apply:
"With proper care and normal weather conditions,
a raspberry planting can remain productive for
12 to 15 years. When the planting begins to
decline (small, crumbly fruits; stunted plants;
low yields; weedy areas), plow it up and replant
in a new location, if possible. If not, wait a year
or two before replanting in the same site."

Thanks. I plan on plowing up the raspberry patch at the end of this season, and replanting again in the same spot in a few years. In the meantime, would it be okay to plant tomato plants in that soil?
Good question. Experts at Cornell University have this to say about rotation with raspberries in that regard:
"Some growers may rotate out (verticillium) infected raspberry patches with alternative crops. However tomatoes, eggplants, peppers, pigweeds, horse nettles, and stone fruits should never be planted as a rotational crop, since they are common hosts of Verticillium."
We don't know that verticillium affected your raspberries, but caution precludes rotation to tomatoes.
