|What would cause the leaves on my roses to be a light yellow instead of a dark green. Not all the leaves are but in spots. I checked there are not bugs. Is it an iron problem?

|Roses can produce yellow leaves for no apparent reason at all. I just pull them off the plant so healthy new leaves will be produced. Sometimes it is caused by heat stress or from overwatering, but if the veins are a deep green and the rest of the leaf is yellow, it indicates a need for iron. Hope this information helps you determine just what the problem might be.
