Hi Hamza this is not the right time for bare rooted roses.after 10 Jan in Islamabad.i think it will be earlier for Karachi,cuse the weather diff.u can get roses even 8 Karachi nursries.
Roses are easily available in Karachi.. nearly all varieties which are available in Pakistan.. you should visit Korangi Road there are lots of nurseries ... all of the Karsaz nurseries have been relocated there... Indian chambeli is not as fragrant and is also available at nurseries...
