🌱 How to Care for Bitter Orange to Prevent Scale Insects?

💧 How to Water

Water Bitter Orange when the top 1–2 cm of soil feels dry, typically every 7 days in summer and every 10–14 days in winter. Always water at the base, avoiding wetting the foliage. Ensure pots have drainage holes — standing water causes root rot. Reduce watering slightly in winter to encourage spring flowering.

☀️ Lighting

Provide full sun: at least 6 hours of direct sunlight daily. Outdoors, choose the sunniest spot in your garden. Indoors, place near a south- or west-facing window. Insufficient light leads to poor flowering, reduced fruit set, and increased pest susceptibility. Supplemental grow lights can help in winter.

🪴 Ideal Soil

Use a well-draining, loamy-sandy soil mix enriched with organic matter. Ideal pH range is 5.5–7.0. Avoid heavy clay soils that retain moisture. Add a slow-release citrus fertilizer to the planting hole. For containers, use a quality citrus potting mix with added perlite for drainage.
