To promote continuous blooming, deadheading spent flowers is essential. By removing faded blossoms, you encourage the plant to produce more flowers, extending the blooming period. Additionally, removing any yellow or damaged leaves helps maintain the plant’s overall health and appearance.

While Whirlybird nasturtiums are generally pest-resistant, they can occasionally attract aphids, caterpillars, or flea beetles. Regularly inspecting the plants for any signs of pests and addressing the issue promptly can prevent damage and maintain the plant’s vigor.
