Keys To Healthy Roses
Q: Why are the leaves on my roses turning yellow and falling off already? Bubs – Des Moines
A: It’s probably black spot, powdery mildew or rust. Disease-B-Gon is a good product to apply. You need a good spray program about every 3-4 weeks and feed the roses every 4-5 weeks. That’s really the only maintenance they need other than sunlight and moisture.
