🌱 How to Care for Rough Horsetail to Prevent Mealybugs?

💧 How to Water

Keep the soil consistently moist to wet at all times; horsetail is a marginal wetland plant and should never be allowed to dry out completely. In containers, water when the top of the soil begins to feel dry, roughly every 3 days, and it can even sit in a saucer of standing water.

☀️ Lighting

Grows best in full sun to part shade and tolerates deep shade, though stems may become sparser and lankier with less light. A south-facing window or bright outdoor spot with a few hours of direct sun produces the densest growth.

🪴 Ideal Soil

Use a moisture-retentive, slightly acidic to neutral mix (pH 6.0-7.5) such as peat, sand, and perlite. It tolerates a wide range of soils as long as they stay consistently damp; good organic content helps retain moisture.
