How to Deadhead Petunia Flowers

Updated February 21, 2017

Striped, solid or speckled, petunias come in a wide range of types and colours. Whether planted in containers, flower beds or as landscaping, the bright-coloured blooms entrance the observer. Petunias love the sun and work best in direct sunlight or part sun. Deadheading the blooms reinvigorates the plant, allowing for an abundance of blooms all season long. By following the proper technique for deadheading your petunia blooms, you can ensure a healthy season for your plant.

Place container petunias on an outside table for easier cutting. Lay old newspapers under the containers to catch the cut blooms.

Hold the stem of the petunia flower you wish to deadhead. Place the pruning shears 1 inch below the bloom. Angle the pruning shears at a 45 degree angle and cut the bloom.

Deadhead approximately 1/2 of the blooms on each plant. Cut the blooms at least once a week or more if desired.


Sharpen pruning shears regularly to ensure a sharp cut to the stem of the petunia when deadheading.
