Germination Step-by-Step

Step 1 – Cold Stratify 30-60 Days

Place seeds in a zip-lock bag with moist peat moss or vermiculite and refrigerate for 30-60 days. Keep consistently moist but not wet.

Step 2 – Surface Sow

After stratification, sow seeds on the surface of a well-draining seed starting mix. Do not bury deeply — Taiwan Cedar seeds need light to germinate.

Step 3 – Maintain Humidity and Warmth

Cover with a humidity dome. Keep temperatures at 65-75°F. Mist gently rather than watering directly.

Step 4 – Be Patient

Germination can take 3-8 weeks. Do not discard seeds that haven't sprouted early — they remain viable.

Post-Germination Care

• Light: Bright indirect light, then gradually full sun
• Water: Consistently moist, never waterlogged
• Soil: Well-draining, slightly acidic
• Fertilizer: Diluted balanced fertilizer monthly during growing season
• Note: Handle roots carefully — does not like root disturbance
