I am putting together a guide for growing desert roses seeds based on my experience.
Adenium (Desert Rose)
Days to Germinate (3 to 10 days)
Days to Bloom (6 months to 2+ years)
Important: Seeds and seedlings are toxic, so keep away from pets or children.
Adenium (Desert Rose) Seeds Growing Instructions:
1. Soak seeds overnight (or up to 24 hours) with a mixture of 1 tbsp of hydrogen peroxide and a cup of lukewarm water. (Okay for seeds to float.) Use the left over water mixture for the initial watering.
2. Use any clean seedling trays or plastic containers with good drainage. If using humidity dome, remove dome once seedlings start to emerge.
3. Discard unhealthy-looking seeds. Sow the healthy-looking seeds on coarse sand, or 50/50 cactus soil (or potting soil) and perlite. Place the seeds horizontally and using just enough soil to barely cover the seeds. Do not bury deep.
4. Spray the soil with water as needed to keep the soil moist but not too wet. Occasionally, use water mixture with hydrogen peroxide to prevent damping off.
5. Transplant seedlings to individual pots when 2+ months old, same depth, do not bury the caudex deep. Do not water for up to 3 days after transplanting, keep in shade and gradually introduce to direct light.
6. For older seedlings, use fast draining mix, let soil dry before watering. When seedlings are 3+ months old, occasionally water with low dose blooming liquid fertilizer and let it enjoy 6+ hours of direct sun.
7. For additional advice, visit garden.org Adenium forum. Happy Growing!!!
