Water regularly to keep the soil consistently moist, especially during warmer months and when the plant is actively growing. Avoid allowing the soil to dry out completely, as Asiatic Dayflower prefers humid conditions.

Reduce watering slightly in cooler periods but do not let it become bone dry.

Prune Asiatic Dayflower to maintain a tidy appearance and encourage bushier growth. Pinch back leggy stems regularly.

After flowering, you can cut back the plant to prevent excessive self-seeding and to promote a second flush of blooms in the fall. Remove any dead or damaged foliage promptly.

Asiatic Dayflower is easily propagated by seeds sown directly in the garden after the last frost, or started indoors a few weeks prior.

It also readily self-seeds and can be propagated by stem cuttings taken during the growing season. Divisions of established clumps can also be made in spring.

Repot Asiatic Dayflower annually or biennially, preferably in spring, if it becomes root-bound. Choose a pot that is slightly larger than the current one. Ensure the new pot has adequate drainage holes.

Use a well-draining potting mix to prevent waterlogging, which this plant dislikes.
