Seeding Notes
- Scarify
- Scuff up the seed with sandpaper or an emery board before planting.
- Stratify
- Seed needs alternating temps to germinate. Plant in moist soil and refrigerate for 3-4 weeks. For many wildflowers, you can skip stratification if you sow seed in the fall.
- Chill
- Put your seed packet in the fridge for a few weeks before planting seeds.
- Surface sow
- Seeds need light to germinate. Don’t cover them with soil. You can gently pat the seeds down. If seeds are small, water very carefully so they don’t float away.
