August's warm and often dry conditions make deadheading a crucial task for maintaining vibrant gardens. Removing faded blooms from plants like zinnias, petunias, and coneflowers encourages fresh growth, allowing them to thrive despite the summer heat. Timely pruning is essential as it helps these flowers navigate late-season weather fluctuations, extending their colorful display into the fall. This practice also reduces stress on plants weakened by drought, humidity, or storms.
