Most dianthus flowers are easy to grow and can thrive in a range of conditions. They bloom best when given plenty of sun, but they don't like the high heat of mid-summer. Deadheading and some cutting back after the first bloom help to ensure a second bloom later in summer or early in the fall.
Light: Full sun is important for thriving plants, so choose a location that gets at least six hours of light each day. It's best to plan them early in the spring season. They will then be established before the hot summer weather.
Water: Dianthus flowers need weekly watering. Try one inch of water once a week. Avoid water-logging the soil.
Temperature: These plants can tolerate a light frost but don't like a deep freeze. It is possible for some hardier plants to survive outdoors in the winter.
