Torenia anagallis prefers consistently moist soil. Water thoroughly when the top inch of soil feels dry to the touch. Avoid waterlogged conditions, which can lead to root rot.

In hot, dry weather, more frequent watering may be necessary to maintain adequate moisture levels.

Pinch back the tips of young plants to encourage bushier growth. Remove spent flowers regularly to promote continuous blooming and prevent the plant from setting seed.

Prune lightly in late winter or early spring before new growth begins to shape the plant.

Torenia anagallis is easily propagated from seed sown indoors in early spring, or directly outdoors after the last frost. It can also be propagated from stem cuttings taken in late spring or early summer.

Cuttings should be rooted in moist, well-draining potting mix.

Repot Torenia anagallis annually or when the plant becomes root-bound. This is typically done in spring before new growth starts.

Choose a pot that is one size larger than the current one and use a fresh, well-draining potting mix. Ensure the new pot has adequate drainage holes.
