Answer: Yellow leaves, especially on new growth, indicates a nutrient deficiency. Feed your roses (there are several brands available) on a regular schedule and that should correct the problem. If you are already regularly feeding your roses and the leaves are still yellow, it indicates a soil pH that is too high or too low. pH should be between 5.5 and 6.5 to free up the nutrients and make them readily available to the roots of your plant. Best wishes with your roses!
