   • Outdoors: From October to February, when temperatures range between 15–25°C (59–77°F).

   • Indoors or nursery trays: From December to February for early planting before spring.

   • Avoid sowing from April to September, as high summer heat prevents germination and flowering.

2. Sowing Depth:
   Sow seeds 0.5 cm deep in moist, well-drained soil.
   Lightly cover with soil and mist with water to maintain moisture without overwatering.

3. Soil:
   Prefers fertile, well-drained, neutral to slightly alkaline soil.
   Ideal Gulf mix: 40% garden soil + 30% peat moss + 20% perlite + 10% compost.
   Avoid heavy clay soils and waterlogging.

4. Light & Temperature:

   • Germination temperature: 18–22°C (64–72°F).

   • In the Gulf, provide shade during the hottest part of the afternoon to prevent heat stress.

5. Germination Time:
   Seeds germinate in 10–20 days under warm, moist conditions.

6. Transplanting:

   • When seedlings reach 8–10 cm tall, transplant them carefully into garden beds or large pots.

   • Space plants 20–25 cm apart for compact, upright growth.

   • Harden seedlings gradually before full exposure to sunlight.

7. Growing Tips for Gulf Climate:

   • Sunlight: Prefers full morning sun and light afternoon shade for best flowering.
