I was only thinking of keeping it in a basket for a one summer. Then this fall plant it in a large pot.
I have a large deck that is two stories above ground. I was keeping the roses in big pots and push them close to the sunroom and I pile leaves on top then I surround it with styrofoam.
I just find if I give the roses a year or two protected growing in pots I have a better chance of the roses surviving.
This is a bad pic of the area where I have been storing the roses. This was taken before the rehab. I should take new pics of the area. Any how it is the left side in the corner. It protects everything in that corner.
