5. When to Plant
The majority of different types of roses available out there are fine planted at more or less any point throughout the year with the general exception of winter. As a general rule of green thumbs, roses don’t like being exposed to cold – and they won’t take well to being planted (or transplanted) into freezing soil.
If you’re planting your roses outside, the best time to do this is either in fall or autumn, before the ground starts to chill: This way, they have more than enough time to establish themselves and collect the right nutrients to be ready for the flowering stage in time.
This doesn’t necessarily mean that planting roses in the wintertime are impossible: It can still be done, but with a much greater amount of care. Often when planting roses in the winter, it can be done indoors instead – and it’s great if you intend on transplanting them (carefully, of course) when the season changes.
