When to Plant Carnation Seeds
Carnation seeds may be started indoors in the springtime 6 weeks to 2 months before the last frost. If you chose to sow them directly outdoors, be sure that the last frost has occurred. If your winters are mild, carnations seeds may be sown outside from spring until early fall. Carnations will grow as perennials in frost free zones and as annuals where winters are cold.
Where to Plant Carnation Seeds
Carnations do not need a lot of water- except in hot months. Soaker hoses are best. Do not over water as this can cause yellow foliage. Carnations need 4 to 5 hours of sunlight a day. They prefer fertile, well-drained, slightly alkaline (pH 6.75) soil.
How to Plant Carnation Seeds
If starting indoors seeds should be covered thinly with soil and kept moist. Plant 2 to 3 seeds per pot or cell. Germination will occur within 2 weeks if temperatures are between 65-70F. After germination, move seedlings to a sunny, cool place. They may be transplanted to your garden a week or two prior to the final frost.
