I have a problem. Needs some help. I raise my own tomato plants from seeds this year. I don't know if this is were it started or from my Rose bush's. I first found the problem on my Roses. I went to a nursery with some leafs from them. They told me what it was, so I bought some thing from them for it. A few days later it showed up on my tomato plants so I sprayed them to. It only stops for about a week or so then it comes back. I live in southcentral ky. They told me that humidity starts it. My question is. If I mix a low dose of bleach in water and spray the roses and tomato plants will it hurt the plants? If any one can help me I would be very thankful. Have a Great Day and keep gardening.
