Q.roses and black spot
Can you cut a rose back to the ground that gets black spot and transplant it to another spot? Hoping to get rid of the problem.

A series of spray applications of a fungicide called Mancozeb will usually stop black spot in its tracks. This article should help as well: https://www.gardeningknowhow.com/ornamental/flowers/roses/black-spot-roses.htm
