QuestionI have two knock out rose bushes that were planted about three years ago by a landscaper. The first year the bloomed well. Last year that bloomed sporadically and this year even fewer blooms have appeared. Not sure what to do. The plant looks very healthy gets good sun and watered regularly.
AnswerKnock Out roses should bloom very well for you and they shouldn't slowly decline. Using a tomato fertilizer on a plant that doesn't boom well has proven to be useful. Just follow the directions on the package for a mature tomato plant. As I don't know where you garden, the rose could be getting damaged in a cold winter
