Cassia javanica

6 seeds

• Best Time to Sow (Gulf Region):

  • Sow seeds from February to April or September to November, when daytime temperatures range between 20–30°C (68–86°F).

  • Avoid sowing during the peak summer months (May–August) when temperatures exceed 40°C, as young seedlings are sensitive to intense heat and dryness.

• Seed Preparation (Scarification):

  • Cassia javanica seeds have a hard outer coat that must be softened before sowing.

  • To improve germination:

    • Soak seeds in warm water (about 40–50°C) for 12–24 hours, or

    • Lightly scratch or nick the seed coat with sandpaper before soaking.

  • After treatment, seeds should swell slightly, indicating they are ready to plant.

• Sowing Depth:

  • Plant seeds 1–2 cm deep in moist, well-drained soil.

  • Gently firm the soil over the seed and water lightly to settle it.

• Soil Requirements:

  • Prefers sandy-loamy, fertile, and well-draining soil.

  • Ideal Gulf mix: 40% sandy soil + 40% garden soil + 20% compost or organic matter.

  • Ensure excellent drainage to avoid root rot during humid or rainy periods.

• Light & Temperature:

  • Germination temperature: 25–30°C (77–86°F).

  • Requires full sunlight for strong, healthy growth.

  • In very hot areas, provide light shade during the first few weeks to protect seedlings.

• Germination Time:

  • Seeds typically germinate within 10–20 days under warm, moist conditions.

• Transplanting & Spacing:

  • Once seedlings reach 15–20 cm tall, transplant them into individual pots or directly into the ground.

  • Space trees 3–5 meters apart if planting in open areas or landscapes.

  • Choose a sunny, wind-protected location.

• Growing Tips for Gulf Climate:

  • Watering: Keep soil slightly moist during the seedling stage; once established, Cassia javanica becomes drought-tolerant but benefits from weekly deep watering.

  • Feeding: Apply a balanced organic fertilizer every 4–6 weeks during active growth (spring to autumn).

  • Pruning: Lightly prune young trees to shape and remove weak branches.

  • Heat tolerance: Mature trees thrive in the Gulf heat but should be protected from harsh sun while young.

  • Blooms appear from March to June, producing clusters of pink to rose-colored flowers, highly ornamental and fragrant.
