| What have been your most effective organic black spot remedies in your gardens? I've tried to select roses for their disease resistance, but inevitably I get blackspot on most of them during really humid spells. I'm not looking to have exhibition roses. I'd just like to keep them looking a little more clean. Thanks. |

| The only time I see Black Spot on my roses is when the level of organic matter is allowed to decrease because I have not put more compost on the soil, or when I bring a new rose in from a nursey. To treat I will spray with either 1 teaspoon of baking soda in 1 quart of water, or a 50/50 mix of fat free milk and water, spraying every 5 days and then making sure I get the soil worked into a good, healthy soil well mulched. |
