Carnations need slightly alkaline soil to thrive. The soil should therefore be at a pH of 6.75. Peat is an ideal organic matter to add to the soil to help carnations grow.
Plant the seeds in the prepared soil. The seeds should planted 1/8 inch deep. The soil should be well drained, and the seeds should be about 1 foot apart.
Carnations do not need much water. However, the soil where the seeds have been planted should be misted with water occasionally. Carnation seeds should germinate in two to three weeks.
