🌿 The Truth About Growing Lisianthus From Seed

Let’s be real—lisianthus has a reputation:

👉 Slow
👉 Difficult
👉 “Hard to germinate”

But here’s the truth:

Lisianthus is NOT hard—it's just precise.

Most failures come from environment, not seed quality.

This is explained in detail here:

🌡️ Perfect Germination Conditions (THIS is the Key)

Lisianthus seeds need very specific conditions:

  • Soil Temp: 65–72°F
  • Light: REQUIRED (do NOT cover seeds)
  • Moisture: Even, not soaked
  • Humidity: Moderate (domes OK—but watch heat)
  • Time to germinate: 10–21 days

⚠️ Biggest mistake:
Too much heat or too much moisture = failure

💡 Pro Grower Tip (Game-Changer)

Lisianthus seedlings often appear to “do nothing” for weeks.

👉 This is normal.

They are building roots before top growth.

Once established, they explode in growth.
