Q: I have 3 rose of Sharon bushes that are approx. 5 yrs old. all are in at least 6 hrs of sunlite, and about that same conditions I think. One has so many flowers blooming each year, but the other 2 never have. They will bud out but stops there. Is there such a thing as male and female bushes?
No, but lack of sunlight will do it. Is the blooming one hogging the rays by any chance? Best And Happy Yardening, Nancy
