Starting seeds indoors
In colder regions, you should start snapdragon seeds 8-10 weeks before your last average frost date to give your plants plenty of time to grow before the ground thaws.
Snapdragons seeds are tiny black balls that are difficult to handle individually. I like to pour out the packet into a small bowl, then stick a few to my finger to sprinkle in each cell of the seed tray.
Plant the seeds
Snapdragon seeds need light to germinate, so just sprinkle a few seeds per cell on top of the soil.
Light and temperature
The optimum temperature for snapdragon seed germination is 55 to 70°F, so you do not need to use a heat mat under the seed tray. I keep my grow light shelves in the basement where it stays in the low 60s.
Water
Water the seeds with a fine mist to avoid disturbing them on the soil’s surface. Cover the tray with plastic wrap or a humidity dome to keep the soil moist until the seeds sprout.
Transplanting seedlings
Harden off your snapdragon seedlings for a week when temperatures are reliably above 50 degrees during the day before planting them in the garden.
