Since roses are one of those plants that can tolerate a little bit of cold weather you can plant them a little earlier in the year than other plants that might not handle the cold.

The earliest that you can plant roses in Prior Lake is March. However, you really should wait until April if you don't want to take any chances.

The last month that you can plant roses and expect a good harvest is probably August. Any later than that and your roses may not have a chance to grow to maturity. If you are starting your roses indoors then you might be able to get away with starting them a little bit earlier.
