π± How to Care for Blue Jacaranda to Prevent Thrips?
π§ How to Water
Water every 7-14 days when young, allowing the soil to dry slightly between waterings. Once established (2-3 years), Jacaranda is drought-tolerant and rarely needs supplemental watering except during extended dry spells. Avoid overwatering, which leads to root rot.
βοΈ Lighting
Plant in full sun with at least 6 hours of direct sunlight daily. Full sun exposure is essential for abundant flowering. In extremely hot climates, light afternoon shade is tolerated but may reduce bloom intensity.
πͺ΄ Ideal Soil
Prefers sandy, well-drained soils with a slightly acidic to neutral pH (6.0-7.5). Enrich with compost at planting. Avoid clay or poorly drained soils as waterlogged roots will rot. Sandy loam is ideal.
