🌱 How to Care for Common Morning Glory to Prevent Leafminers?

Water once per week during the growing season. Allow the soil to dry slightly between waterings. Avoid waterlogging as roots are susceptible to rot in compacted or poorly drained soil.

☀️ Lighting

Requires at least 6-8 hours of direct sunlight daily for abundant flowering. In partial shade the plant grows but blooms poorly. Position it in a south or east-facing location to maximize sun exposure.

🪴 Ideal Soil
