  • Remove wilted foliage: This will encourage flowers and leaves to grow back.
  • Remove shoots after the first flowering: For some perennials, such as yarrow, this results in a second flowering phase. All other perennials will benefit as well, as this will result in even more abundant blooms the next year.
  • Fertilizing: You can also support the growth of the flowers by adding fertilizer.
