Answer: When roses develop yellowing leaves it is usually due to water or fertilizer issues but it might also indicate the beginnings of a disease called black spot. If the leaves are yellow but not spotty, it may be time to feed them or to check the soil moisture. Roses like to be watered regularly but the soil needs to dry out a bit between waterings or the roots can drown. Hope this information helps you determine just what's going on with your miniature rose.
