Step 4

Repeat foliar application every 7-10 days until symptoms improve

Step 5

Follow up with soil application for sustained results

🌱 How to Care for Great Bougainvillea to Prevent Iron Deficiency?

💧 How to Water

Water deeply but infrequently — allow the soil to dry out almost completely between waterings (every 7–14 days in summer). Established in-ground plants need little supplemental water. Overwatering is the most common mistake; it causes leaf drop, root rot, and poor flowering.

☀️ Lighting

Bougainvillea demands full sun — a minimum of 6 to 8 hours of direct sunlight daily. Without intense direct light, the plant produces lush foliage but rarely initiates bract production. Position on south- or west-facing walls for best results.

🪴 Ideal Soil

Use a light, fast-draining growing mix such as a blend of loam, coarse sand, and perlite. Ideal pH is 5.5–6.5. Avoid heavy clay soils or waterlogged conditions. Good drainage is critical to prevent root rot.
