🌱 How to Care for Bittersweet Nightshade to Prevent Thrips?

💧 How to Water

Water deeply every 7 days, allowing the top inch of soil to dry slightly between waterings. Avoid waterlogging which causes root rot. During hot summers, check soil moisture more frequently and water when the top layer feels barely dry.

☀️ Lighting

Thrives in partial shade to filtered sun — ideally 4–6 hours of indirect or dappled light daily. Tolerates full sun in cooler climates but may scorch in intense afternoon heat. Morning light is ideal.

🪴 Ideal Soil

Prefers moist, loamy, well-draining soil rich in organic matter. pH range of 5.5–7.5. Avoid heavy clay (poor drainage) or pure sandy soils (dries too fast). Amend with compost for best results.
