How late in the year would it be too late to plant a root rose bush, Aug. or Sept?
Fall Planting Roses
I really do not like to plant new rosebushes any later than mid July. I have planted some as late as mid-august but had to baby them through the winter and make sure they had good soils moisture. The root system needs all the time it can get to get established so it can support a big rose and the beautiful blooms we all love.
