How To Deadhead Dianthus

Dianthus is known for having the ability to produce flowers and bloom profusely every year. This attribute can be made realistic and enhanced through deadheading. After blooming, the dianthus loses its beautiful coloration, and its petals start to fade and witter.

At this point, deadheading should be done to bring back its beauty and make it bloom again. Faded petals can be removed easily with scissors, pruning shear, or hands to make the dianthus look healthy again.

Since the importance of deadheading is known now, the question that needs to be answered is, how should or can it be done? The energy that should be directed towards the production of seeds is diverted towards blooming. Deadheading dianthus gives them the chance to live and bloom attractively again.

Deadheading requires extra work from gardeners but the advantages that come with it make it worth the effort. Below are how dianthus should be deadheaded for better result.


  1. Wait till fading of the petals start

Dianthus are capable of blooming every year and they become even more attractive after every bloom. Though they can become unattractive after the flowers are spent, that does not stop them from blooming again if properly taken care of.

After flowering, when the blooming cycle has completed, dianthus’s pink, red or lavender flower starts to fade and becomes unattractive, losing its beautiful coloration.

When this happens, that is, when the petals start to fade, then deadheading can be done. Dianthus can also be cut in full bloom and taken in a bouquet to serve as a gift or for indoor beautification. This also helps in the deadheading, though all the petals should not be cut.

  1. Cutting the faded petals to avoid the production of seed

Deadheading is just like another word for pruning. Some flowering plants bloom for a relatively lengthy period, and along the line grows faded flowers along with fresh blossoms. The plants’ appearances become worse and less attractive despite the presence of flowers in normal conditions. Therefore, cutting and removal of unattractive flowers is one ideal option to restore their beauty.

When the petals of dianthus start to fade, normal pruning procedures can be followed to eliminate the bad flowers. The petals of the plant should not be removed totally and some should be saved for photosynthesis. However, cutting petals close to the root should be avoided as the process may expose the root to diseases and pests.

Only the faded petals should be removed and the remaining flower should be left so the plant can get carbon dioxide through photosynthesis for their feeding. This will help the dianthus to grow healthy. Cutting faded flowers also prevents the dianthus from producing seeds.

Flowers that have been affected by insects and pests can be trimmed or eradicated and keep the plant aesthetic. The cut flowers should be packed to avoid littering and can be used for compost manure. The flowers plucked for a bouquet should be placed in water immediately.

  1. Monitor the dianthus throughout the summer and fall

As mentioned earlier, deadheading can be done once or twice in a growing season of dianthus and may also be done every week, depending on the species. It’s essential to know the particular type of dianthus that one grows.

A carnation is a type of dianthus popularly believed to initially surface on the ground where the tears of Mary the Virgin fell. Another name it’s called is the flower of God. Carnations must not lack water and should be planted to access the sun for photosynthesis. They flourish on fertile soil and where there’s adequate irrigation.

However, over-watering is not helpful for their growth. Carnations, when properly deadheaded, do not only bloom year after year but also become more attractive.

It’s important to monitor dianthus after cutting and pinching of the faded and wittering flowers off the plant. Water should be supplied adequately and in the case of insufficient nutrients from the soil, fertilizers can be supplied to enhance the growth of the dianthus.

Shades should be avoided around the dianthus to ensure that they get enough sun and photosynthesis efficiently. When dianthus gets enough sun, they have the energy required for re-blooming.

Conclusively, dianthus should be deadheaded for them to bloom again year after year instead of leaving them to produce seeds and lose their beauty. Every condition should be well met to ensure good results. Gardeners should make sure they grow dianthus on fertile and well-drained soil, supply adequate water once a week but avoid too much water.

And after blooming, when the flowers are spent, deadheading should be done again to get a more attractive bloom year after year.
