There aren't much fruit produced up here and cutting there will tend to stiffen the cane and improve the crop. And then, again in the spring, we want to thin out the number of canes to about six to eight canes per running foot of row. You don't have to mulch raspberries. They're very hardy and they survive the winter just fine. But we do have to mulch strawberries.
Strawberries are a little more tender.
We want to cover them over with two to three inches of a light, lofty material that will provide some insulation and keep the temperature from fluctuating. So, straw or marsh hay, either one works very well. I would wait a little while. You want a little frost in the soil. Usually in southern Wisconsin, about Thanksgiving is the right time.
