Summer gardening activities and maintenance focus on seasonal festivals and the care of specific flowering plants. In the Pacific Northwest, sunflower festivals in the Portland area offer various attractions including flower picking and mazes.

To maintain summer blooms, particularly dahlias, experts recommend specific care routines. These include deadheading spent blooms to redirect energy toward new buds and implementing deep watering schedules to combat heat stress and prevent fungal diseases. For balcony gardening, resilient varieties such as Pelargoniums, Petunias, and Calibrachoa are suggested to ensure long-lasting color through the summer and autumn.
