How to care for Water Lobelia

Water

Water Lobelia should be watered regularly, allowing the soil to dry out between waterings.

Soil

Water Lobelia loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.

Insufficient light can result in slow growth and leaf drop, so it's important to find a well-lit location for this plant.

Dormancy

During the wintertime, it's common for Water Lobelia to go dormant and their growth may slow down, so waterings should be spaced out more.
