🌱 How to Care for Sweet Orange to Prevent Aphids?

💧 How to Water

Water every 5-7 days in summer and every 10-14 days in winter. Allow the top 2-3 inches of soil to dry between waterings. Avoid waterlogging — sweet orange is susceptible to root rot. Ensure excellent drainage in both containers and garden beds. Morning watering is preferred.

☀️ Lighting

Sweet orange demands full sun — minimum 6-8 hours of direct sunlight per day. Choose the sunniest spot in your garden, away from shade-casting structures or trees. Insufficient light results in poor fruiting and weak growth. South or southwest-facing positions are ideal in the Northern Hemisphere.

🪴 Ideal Soil

Use fertile, well-draining sandy loam or loamy soil with a pH of 6.0-7.5. Amend clay soils with coarse sand and organic compost to improve drainage. Avoid compacted or waterlogged soils. Raised beds or mounded planting sites work well in heavier soils. Test soil pH annually.
