The earliest settlers from England and France brought with them to America a much-loved flower known as the carnation. A member of the dianthus family, perpetual carnations are the workhorses of the floral world. They create everything from long-lasting wedding boutonnières to funeral sprays. As their name implies, perpetual carnations produce flowers year-round as long as they are maintained in an appropriate environment. The most common way to grow perpetual carnations is inside a greenhouse.
Plant in a multipurpose potting compost.
Place plants in a sunny location, where they can receive both heat and light.
Stake plants with plant supports as they grow.
Water two to three times a week to maintain moist, but not wet, soil.
Pinch off the growing tip of plants when they exceed about 6 inches to make plants bush out into shoots. Each shoot will produce a flower. Pinch off subsequent shoots at alternating times to stagger flowers.
Feed a balanced flower food such as Miracle Gro Bloom Booster according to package directions.
Remove all developing buds except those on the stem ends.
Maintain a temperature of at least 7.22 degrees Celsius in flowers' environment.
In winter months, expose carnations to additional light from a 100 watt bulb placed about 5 feet above plants.
