🌱 How to Start Sweet Pea Seeds

1. Scarify or soak: Nick the seed coat or soak overnight to speed germination.

2. Use deep pots: Sweet peas form taproots, so root trainers or 4-inch pots work best.

3. Cool soil temps: Germination is strongest at 55–65°F.

4. Pinch young plants: When 6 inches tall, pinch tips to encourage branching and more stems.

5. Harden & transplant: Move outdoors when soil is workable, spacing plants 6–8 inches apart on trellises or netting.
