Shrub roses not blooming
We have red shrub roses that are a few years old. They are spread out with space, mulched, get 6-8 hours of sunlight per day, fertilized at least monthly, etc. , not watered from the top unless it rains, etc. In other words, well taken care of and were bought at a great nursery. We get very few if any blooms. Other shrub roses around the area that get no special care are beautiful. Any tips.
