Per the manufacturer, If the roses have been planted over a week or longer, and are healthy, it is fine to spray Sevin Ready to Spray Insect Killer. It’s recommended to apply at the coolest time of the day. If it has been less than a week there are other things to consider. In that case,it is best to contact the manufacturer, Garden Tech, at 1-866-945-5033.
