Carnations are adaptable plants that are easy to care for, even for novice gardeners. They need to be planted in a sheltered spot that receives approximately four to six hours of full sun daily. Carnations also require fertile, well-draining soils with pH levels ranging from 6.5 to 8.5.

Water carnations once a week or whenever the top 2 to 3 inches of soil feel dry. Fertilize every three to four months using a slow-release fertilizer. Alternatively, feed carnations every month or two using diluted liquid fertilizer.
