Growing Tips
- 1Plant snapdragons in a spot with full sun for the best blooms, ensuring they receive at least 6 hours of sunlight daily.
- 2Water them regularly, keeping the soil consistently moist but not waterlogged, especially during dry spells.
- 3Use well-draining soil enriched with organic matter, and space plants about 6 to 12 inches apart to allow for good air circulation and prevent disease.

How to Harvest
- 1Harvest snapdragons when the flowers are fully open but before they start to wilt.

- 3Avoid pulling the stems to prevent damaging the plant.
Step 5
Saving Seeds
How to Save Seeds
Saving seeds from your Snapdragon plant is easy and rewarding! Once the flowers fade, let the seed pods dry on the plant until they turn brown and start to split open. Gently collect the tiny seeds by shaking the pods into a paper envelope or small container. Don’t worry if you’ve never done this before—Snapdragon seeds are simple to gather, and you’ll love growing your own plants next season! Store your seeds in a cool, dry place, like a labeled envelope in a jar or tin, and they’ll be ready to plant when spring arrives. You’ve got this!
