How to Deadhead Snapdragon Flowers


When a gardener removes the spent blossoms from a plant--called deadheading--he helps the plant conserve growing energy. Deadheading annuals, such as snapdragons, will help the flowering plants continue to bloom prolifically throughout the growing season. If a gardener allows spent flowers to remain attached to a plant, the plant will continue to direct energy to these blossoms to generate seeds. Deadhead snapdragons to keep your flower gardens neat, tidy and full of bright color.

Step 1

Watch the snapdragons for the first round of blossoms that will occur early in the growing season. When you see these blossoms begin to fade, cut them from the plant with the pruning shears immediately under the blossoms.

Step 2

Place the spent blossoms in the bucket to collect them as you remove them from the snapdragon plants.

Step 3

Dump the spent blossoms into a compost heap (if you have one) to use them to create beneficial compost to amend your soil.

Step 4

Continue to watch the snapdragons as the growing season progresses, and remove the blossoms immediately when they fade on the plants by cutting them off with the pruning shears.

Tips and Warnings

  • Do not leave the removed plant debris on the soil beneath the snapdragons because this can contribute to fungal infections among plants. Always discard the removed plant material properly either in a compost bin or in the garbage.
