Q.When do wild roses bloom?
We found a wild rose bush in the edge of woods and transplanted it. When can we expect it to bloom?

I forgot to give you this link to an article on wild roses and care:

It should bloom for you the following Spring after transplanting. Some bloom only once per season and that is early in the season. Others will bloom very well while some young ones that have yet to mature can take 2 to 3 years.
