How to cover the curving rose?

Two years ago, I wrote on the catalog of the curving rose. On the very first year after landing, she released buds, but I was advised to cut them out to give a young plant to grow and well root.
For the next summer, several buds have appeared. They beat away, and I did not wait for more floweries. Rose kicked out two-meter shoots, and all over it. I was upset that I paid a lot of money, but a little sense. I decided to stop it for the winter, and in the spring at this place to plant a new bush. But it did not get a rose in this spring. But my Rosa who guessed last year, despite the cold winter, perfectly overwhelmed, went into growth and even bloomed in three stages. Flowers are odorless and arranged with whole bouquets! So now I changed my mind to dig it.
That's just me tormented by one question. I can not understand how to bury the curving rose on the winter - completely tilt to the ground and sprinkle all the branches or only one base?
