How to Grow Snapdragons From Seed

By Jenny Harrington ; Updated September 21, 2017

Snapdragons are used in beds and containers. They bloom profusely during cool weather in spring and autumn, with each stem being covered in small flowers. A fragrant flower, they do well near patios where the scent and sight of the snapdragon can be enjoyed. Summer heat causes them to wilt, so containers allow you to move them to a cooler and shadier area if desired. Growing snapdragons from seed is an inexpensive way to produce many of these plants for beds and pots throughout your landscaping.

Fill individual seed starting pots with sterile potting soil. Mix your own by combining 1 part peat moss with 1 part vermiculite.

Sow three to five seeds per pot directly on the soil surface. Cover with a 1/8 inch layer of vermiculite.

Moisten the soil thoroughly and cover with plastic wrap to preserve the moisture while seeds germinate. Place the pots in a 65 degree Fahrenheit room until germination occurs, approximately five to ten days.

Remove the plastic wrap as soon as seedlings emerge. Place the snapdragons in a sunny windowsill in a 65 to 70 degree room.

Water enough to moisten the soil. Allow the soil surface to dry out slightly between watering.

Transplant outside after the last frost in spring. Choose a well drained bed in full to partial sun or transplant into a container filled with light potting soil.
