Available in many different varieties and cultivars, snapdragons belong to the family Scrophulariaceae . Snapdragons are usually grown as annuals even though they are perennials. Snapdragons are best grown in full sun, and like to be fed and watered on a regular basis.
Snapdragons are among the best flowers for sunny borders and cutting.
The time that it usually takes for radicle emergence to occur is between 4-8 days. The soil EC should remain below 0.5. At this time, the grower is through with the germination stages and must now focus on growing the plants that have germinated up to the required size for transplanting. The period from when the cotyledons have expanded to the growth of all true leaves is known as stage 3 and usually takes between 14-21 days for snapdragons. Begin feeding at 100-150 ppm, once per week, making sure that the soil EC remains below 0.75.
