hello, I've had a rosebush for almost 20 years, it always bloomed until the last few years, now its big and healthy and always growing new shots, but no longer blooms..ideas?
Are you pruning it annually: removing old, gray canes, canes that cross/rub and canes that grow toward the middle? If you have been feeding it regularly, get a soil test to see if there is a nutrient problem. Deficiencies and toxicity can lead to lack of blooms. Getting it through your state/county extension service gives the most information. More info here: https://www.gardeningknowhow.com/ornamental/flowers/roses/no-blooms-on-roses.htm
