Stu Dalton, ARS Master Rosarian and UCCE Master Gardener San Mateo and San Francisco Counties will be discussing midyear care which emphasizes removing spent blooms (aka deadheading), opening the middle and summer pruning, watering deeply, mulching, improving soil health and checking for issues including pests and diseases. Planting a variety of plants that attract beneficials can lessen issues. The heat, then rain in the mid-bay microclimate hit the early first boom hard, with high amounts of blackspot, rust and mildew. Stu will talk about his Integrated Pest Management (IPM) approach. He now grows about 130 varieties and more than 230 roses. Stu’s valuable presentation will help us prepare now for blooms through November.
