Dianthus Barbatus: How to grow?

Dianthus Barbatus seed must be sown in a cold frame between May and June. Usually, the seed takes two to three weeks to sprout. Prick the seedlings out into individual pots when they are big enough to handle them, and then plant them outside in the summer or fall. 

The young plants can also be planted outside in the late spring after the seed has been thinly dispersed on an outdoor seedbed. It is better to pot up smaller clumps and grow them in a cold frame until they are rooted effectively. Larger clumps can be transplanted directly into their permanent locations. In the spring, sow them outside.
