To properly care for carnations, provide the plant with full sunlight and ample space to grow. Surround the plant's bedding area with organic materials, while watering the roots sufficiently every week. To achieve this task you need only access to sunlight and water, an organic fertilizer and scissors for trimming.
Carnations prefer full sunlight. However, if growing the plants in an extremely hot climate, it may be necessary to provide partial shade.
In order to give the plants proper circulation, keep 10 to 12 inches of space between each plant.
Spread plant material, such as shredded leaves or dry grass, near the carnations without actually touching them. This helps to keep the soil moist and temperate, while also helping to prevent weeds.
Carnations should receive 1 inch of water every week, whether through watering or rain. To prevent fungal spots on the leaves, water the roots instead of the foliage.
Tall carnations may not be able to support the weight of their heads. Gently tie them to a stake for support.
Use a water-soluble fertilizer with a ratio of 5-10-10 or less.
Encourage repeating blooms by removing wilted flowers. Make a cut just below the wilted bloom on the stem.
After winter kills the plant above the ground, cut it back to 1 or 2 inches above the crown.
