🌱 How to Care for Mexican Primrose-Willow to Prevent Slugs and Snails?

💧 How to Water

Keep the soil constantly moist or slightly waterlogged—this species tolerates and even thrives in flooded soils. Water every 2–3 days or whenever the substrate surface begins to dry. In water gardens, it can be grown with roots permanently submerged in up to 15 cm of water. Avoid long periods of drought, as the leaves wilt quickly.

☀️ Lighting

Requires full sun for vigorous development and abundant flowering—ideally 6 to 8 hours of direct sunlight per day. Tolerates partial shade, but with fewer flowers and slower growth. It is one of the most light-demanding plants in the Onagraceae family; it is not suitable for indoor environments without intense artificial lighting.

🪴 Ideal Soil

Prefers soils rich in organic matter, fertile, and with good moisture retention. In water gardens, use clay substrate or heavy soil mixed with organic compost. The ideal pH ranges from 6.0 to 7.5. Avoid poor sandy soils, as the plant requires constant nutrients to sustain its rapid growth.
