Information on Growing Carnations


The carnation, or Dianthus caryophyllus, is a popular cut flower. These flowers are two to three inches wide and come in a variety of colors. White carnations can be dyed any color desired.


Carnations like good drainage and slightly alkaline soil. They grow best in cooler climates and enjoy fertile soils and sunny locations.


Seeds germinate in two to three weeks when the weather stays between 65 and 75 degrees Fahrenheit.

Flower Care

Remove dying blossoms to encourage an extended blooming period. The tall flowers need support or they will flop over.


Every couple of years, divide the carnation plant cluster. This keeps the plant attractive and growing vigorously.


Pick the carnation flowers when they are just barely open. The best time of day to pick is mid-afternoon. Carnations can be stored dry for several weeks in a refrigerator.
