Plant-health prevention note: Rotate planting locations, avoid overcrowding and prolonged leaf wetness, and remove badly diseased debris after the season. Pest-prevention note: Inspect buds and stems regularly, encourage beneficial insects, and protect developing seed heads with netting if birds are taking a large share.
