black spot driving me insane - June 23rd, 2005 at 10:37 AM
I tried soap shield from gardensalive. I had to cut 2 bushes completely down since the first application about a month ago. Almost every morning I pick off any infected leaves on the other bushes. So far, only 2 of my 7 bushes haven't been affected. I water only in the morning. I have a very thin layer of hardwood mulch on the bed. Could that be the problem?
I'm reluctantly considering resorting to chemicals. I applied soap shield again the day before yesterday, after picking off all the infected leaves (and that's a lot of picking with all the bushes we have). I noticed more blackspot yesterday and today. I'm at a loss for how I can keep it from recurring constantly. I wouldn't mind some spots on my leaves, but I've seen it spread over an entire bush and we had to cut it to the ground.
Please help!
