Seeding
The good seeding season is the mid to end spring. It is recommended to plant them directly in container, because their germination rate is pretty high, and the size of the seeds is large enough to be treated easily.
It is recommended to keep 3 inches of interval to seed them, because they grow big.

Growth Period
It is recommended to cut the growth point when they are 8 inches high. It encourages them to have new branches and have more flowers.
If the flower grows large, you may need something to support the head to keep it from facing down.
If you pick the fading flowers right away, new flowers can obtain more nutrition.
