Here are five short germination tips for Philadelphus brachybotrys (Mock Orange) seeds:
 
Cold Stratification – Store seeds in a moist paper towel inside a sealed plastic bag in the refrigerator (2–5°C) for 4–6 weeks to improve germination.
 
Surface Sowing – Do not bury the seeds; simply press them lightly onto the surface of well-draining soil, as they need light to germinate.
 
Moisture & Temperature – Keep the soil evenly moist but not waterlogged, and maintain a temperature of 15–20°C for optimal germination.
 
Indirect Light – Place the seed tray in a bright, indirect light location to encourage sprouting.
 
Patience & Ventilation – Germination can take 2–6 weeks, so be patient and ensure good airflow to prevent fungal issues.
