Q.Why Do I Have These Yellow Leaves On My Rose Bush?
About 10 days ago I sprayed my rosebush with a product that was to prevent black spot, insects and other molds. Was to make my leaves healthy. I have been watering from the base and not putting water on the leaves. They looked great two days But last night I noticed the leaves turning yellow on areas. I can spray again (but I did not a few days ago since the leaves look perfect). What is the cause of the yellow leaves and what should I do? I’ve got tons of buds…. they have not opened yet on this bush
