How to Deadhead Annuals

In this article we are to going to learn how to deadhead annuals. Deadheading is the process of pruning away dead or wilted flowers from a plant. Deadheading the annuals in your garden is an important gardening chore because it:

  • Increases the time span over which annuals bloom
  • Increases the number of blooms on each plant
  • Improves the appearance of the plant
  • Reduces seed production in the flowers, which makes it easier for you to control how your garden will look

How Deadheading Works

All annuals follow a similar life pattern: they sprout from seeds, grow foliage, produce flowers, and then, when the flowers die, they produce seeds. When you deadhead spent, or wilted, flowers, you keep the plant from reaching the seed production stage and instead keep its energy focused on flower production.

When to Deadhead

While your garden is in bloom, make regular rounds inspecting the flowers. You should deadhead any bloom that has begun to fade and lose petals.

How to Deadhead

The technique you should use to deadhead flowers on an annual depends on the thickness of the plant’s stems and the way that the plant’s flowers are arranged on its stems. No matter how you deadhead, make sure to take off both the faded flower and the seed bud at the flower’s base.

Deadheading and Stem Thickness

You can deadhead plants with thin flower stems using just your fingers—pinch the stem between thumb and pointer finger at the point where you want to remove the stem.

For plants with thicker stems, you’re better off using gardening shears or hedge clippers.

If you’re not sure how to deadhead a particular type of plant in your garden, first try deadheading it using your fingers. If it’s easy for you to make a clean cut in the stem, then just keep deadheading with your fingers. If not, use shears or clippers instead.

Deadheading and Flower Arrangement

The best way to deadhead a plant also depends on how the plant’s flowers are arranged on its stems:

  • Plants with a few stems, each with a single flower, above a base of foliage: Cut the entire stem down to the base of the foliage.
  • Plants with multiple stems, each with one flower: Cut the stem back to the first set of leaves.
  • Plants with multiple flowers on one stem: Deadhead just below each flower when it begins fade. When a stem no longer contains any flowers, cut the whole stem almost all the way to the ground.
  • Plants that produce clusters of many flowers over a base of foliage: These plants produce so many flowers and stems that deadheading stem by stem would be too time-consuming. Instead, use a hedge clipper to cut away all the faded flowers at once.
