Answer: The best times to transplant a rose bush are in very early spring as soon as the soil can be worked and then in the fall. The reason for this is to allow the roots time to grow before there is so much pressure for the top of the plant to grow for the season.
A new rose that has been container grown and is acclimated to the outdoors can be planted any time the soil can be worked. If it has been kept in a greenhouse and is very tender, you will need to gradually acclimate it to the outdoors and protect it from freezes.
A dormant bare root rose can be planted in very early spring so it can wake up naturally with the season. These should ideally be planted while still dormant.
