November is going to be much like October. The nights are getting much cooler. If you are in the low deserts, continue to fertilize your roses once every two weeks with Miracle Gro. Or if you prefer to fertilize less often, use Oscomote Vegetable time released fertilizer, 15-15-15. In the higher deserts and mountains, stop fertilizing all together now.
Remember, if you are using Miracle Gro, it is still wise to use it early in the morning, as the sun is rising, or late in the afternoon as the sun is setting. This helps prevent the fertilizer from burning the leaves of your plants, which could happen on warmer days with the sun shining directly down on your rose bushes.
You can now reduce the amount of water you use to water your roses. I generally cut my watering cycles from three times a week to two times a week for November and once a week in December/January. Especially if we are getting a lot of winter rain, as we commonly do.
Yes, cut them back to about knee height so they are easier for you to move. Then dig them out, keeping as much as the roots intact with the soil as possible. If you loose a significant amount of the root ball, I would cut the canes back to about one foot.
