Germinating Shiso (Perilla) Seeds: Depth, Freshness, and Tips

Key Germination Rule

Cover seeds with soil 3× their thickness. Too deep = no emergence.

Check Seed Viability

• Ask seller harvest date.
• Shiso seed is short‑lived.

Still Stuck?

Try cold stratification (2 weeks in fridge) or bottom heat (70–75 °F). Light not required for germination.
