Plant your roses ASAP! Prior to planting, we suggest you soak the roses for 24 hours, tops and all, in water. This helps hydrate the plant and will help it get a good start in its new home. Select a location in your garden that gets a minimum of six hours of direct sun, preferably afternoon sun...global warming is good!
So, dig that hole about 2' deep and 2' wide, build a cone in the bottom of the hole to spread the roots over. If you are replacing an established rose in your garden with a new bush, remove all the soil and roots completely. Then refill the hole with a good planting mix and some of your own garden soil. Water the new planting thoroughly and top it off with a good mulch.
Roses need room to breath. Avoid crowding them together. Use the table above as a guide.
