🌱 How to Care for Horseshoe Geranium to Prevent Thrips?

💧 How to Water

Water thoroughly every 7-14 days, allowing the top 2-3 cm of soil to dry out completely between waterings. Overwatering is the most common cause of problems — when in doubt, wait. Water at the base to avoid wetting the foliage, which can promote fungal disease.

☀️ Lighting

Place in full sun — at least 6 hours of direct sunlight daily. A south or west-facing window indoors, or an unobstructed outdoor spot. Insufficient light leads to leggy growth and reduced flowering. This is a true sun plant.

🪴 Ideal Soil

Use a free-draining potting mix with perlite or coarse sand added. Never leave in waterlogged soil. A slightly alkaline to neutral pH (6.0–7.0) is ideal. Ensure pots have drainage holes to prevent root rot.
