  • Plant the seeds about 1 inch deep in the soil and cover lightly with soil.
  • Place the seed tray or pots in a warm, bright location with indirect sunlight. A temperature range of 20-30°C (68-86°F) is ideal.
  • Keep the soil moist by watering regularly, but avoid overwatering as this can cause the seeds to rot.
  • The seeds should germinate in 3-4 weeks. Once the seedlings have grown to a height of 2-3 inches, they can be transplanted into larger pots or directly into the ground.
