Growing carnations in pots is a great way to grow these beautiful scented flowers so they can be enjoyed in a sunny spot in your home or by an entryway giving your guests a wonderful aroma as they walk through your door.
Carnations are a species of Dianthus believed to be native to the Mediterranean region however its exact origin isn’t known as it has been widely cultivated.
Carnations are perennial flowers however they are treated as annuals in colder regions. These cold and frost tolerant plants will grow to a height of 31 ½ inches (80cm) tall. They have grey green foliage with frilled single or double blooms in many different colors including shades of red, white, pink, orange and violet. Carnation blooms are usually given to express love.
Carnations in Pots
Whether you prefer an inside or outside location, growing carnations in pots is easy. Carnations like a neutral to slightly alkaline soil which is free draining. For pots it is easy to get the right soil by simply using your favorite potting mix. It doesn’t need to be a high-quality mix as long as you use liquid fertilizer every two to four weeks to promote growth.
Carnations like full sun in cooler climates however if you live in a warm climate it is best to protect the plants from the afternoon sun.
It is best to choose a self-watering planter for indoors or a pot with a saucer. Place in a position which gets at least half a day of sun and has good air circulation. This 8 inch self watering and self aerating pot with a deep reservoir has a unique design to prevent water rings on your floor. It is highly rated on Amazon. (Paid link)
As these are perennial plants it is definitely worth looking for seedlings. They can be found in punnets of six or more plants which will fill a large pot. Look for healthy plants which have no yellowing of the leaves.

How to grow carnations in pots.
- Fill the Pot
Fill your pot up to an inch (2.5cm) from the top with the potting mix.
Water the pot and the punnet of carnation seedlings well.
Make holes in the pot 6 – 8 inches (15 – 20cm) apart and 4 – 8 inches (10 – 15cm) deep. Gently pull apart the roots of the seedlings then plant each one in a hole. Form down the soil then water in well.
- Protect from Birds
Protect the seedlings from birds if they are a problem in your area by placing wire mesh or bird netting over the top. This can be removed after the carnations begin to grow and their roots develop.
Use a half strength liquid fertilizer two weeks after planting then use a full-strength fertilizer every two to four weeks during the warmer months.
- Support the Stems
The long stems may need to be supported by either placing a stake in the middle then tying loosely to the stake or wrap a piece of twine around the middle of the stems. Be careful not to tie the twine too tight. The leaves will grow over the twine and the stems will support each other.
- Mid Summer Prune
The carnations will flower 12 to 16 weeks after the seedlings are planted. After flowering in mid-summer, prune the plant back by about a quarter cutting just above a leaf which is where the new growth will appear. This will encourage new growth and more flowers.
- Winter Prune
Prune back in the winter before the new growth appears in the spring. Cut the stems an inch (2.5cm) from the ground.
When growing carnations in pots in a colder region it is a good idea to put your pot undercover to protect the plant from frost. This will ensure you will have new growth in the spring.
