Question From: MICHIGAN
Q: Last spring I raked out mulch and the top layer of soil in my four raised beds and top dressed them with bags of commercial flower and vegetable soil. I planted cucumber plants and three tomato plants (two Beefsteak and one San Marzano) each in their own raised bed along with White Knight japanese eggplant, broccoli, peppers, etc. and put fresh black mulch around all of them. During the summer some tomato leaf branches started to turn yellow and curl and I removed them. I still had blossoms and fruit into September but the disease was obviously spreading and affecting my egg plants. Admittedly I forgot to turn off the joined soaker hoses several (3? 4?) times, once overnight. Must I remove all the soil in my two foot high raised beds to stop this blight or is there a fungicide I can treat the soil with before I plant next spring?
