Bare root roses should be planted between November and March, while containerized roses can go into the ground at any time of year. If possible, opt to plant roses in bare root form in winter or early spring to give your new roses the best possible start.

There isn't a single best month to plant roses, and the best month will depend on your climate and whether you're planting potted or bare root roses. As a good rule of thumb, however, figure on planting bare root roses in late winter to early spring (such as March) and plant potted roses later in the spring to early summer (such as May).
