I love roses. I plant them in every house I live in. I used to take care of them diligently, spraying for black spot and fertilizing regularly. Once I sprayed so much of the poison that I poisoned myself and had the runs for a few days. Better than dieting, I must have lost 10 pounds that week. Now I let nature take care of them. Maybe a little fertilizer, but not all that pesticide/fungicide stuff.
