For optimal germination rates, initiate seed propagation indoors under controlled conditions—unless the species exhibits a high sensitivity to root disturbance. This approach allows precise regulation of temperature, humidity, and light, improving germination consistency and seedling viability. Do not skip any recommended seed treatments, as they are essential for uniform and successful germination.
Seed Treatment
Step 1: Scarification: Lightly nick the seed coat with a nail file.
Step 2: Soaking: Soak seeds in warm water for 24 hours.
When to Sow Indoors
Start seeds indoors at any time of year using a heat mat and grow lights. Best results occur in spring or early summer.
Optimum Germination Temperature: Use a heat mat to maintain a steady temperature of 21–27°C (70–80°F)
Germination Time: 30–120 days (1 to 4 months), but can take longer
Light Requirements for Germination
Needs light to germinate. Do not cover seeds with soil.
Use grow lights to maintain 12–16 hours of light per day.
How to Sow Indoors
Sow on the surface of a pre-moistened, sterile seed-starting mix. Gently press seeds into the surface without covering.
Humidity
Use a humidity dome or clear cover to maintain consistent moisture during germination. Open the dome BRIEFLY once per day to allow fresh air in and reduce mold risk. Remove the dome entirely once seedlings emerge.
