knockout rose planting
I just bought a double knockout rose. I am in zone 6. Should I plant it now? I have an unheated sun room. I think it is late to plant in zone 6. I also have a rose in a planter that I plan on putting in the sun room.

Placing your new rosebush in the sun room sounds like the best choice.Planting it this late would be risky business. Keep an eye on the soils moisture for both all through the winter season. If the knockout rosebush is in its nursery pot, you might want to transplant it into a larger pot that has drainage holes in the bottom. Gives the root system more room to spread out.
