Water regularly, keeping the soil consistently moist but not waterlogged, especially during the growing season. Allow the top inch of soil to dry slightly between waterings.

Reduce watering in winter, allowing the soil to dry out more between waterings to prevent root rot.

Prune to maintain a tidy shape and encourage bushier growth. Pinch back the tips of stems in spring and summer to prevent legginess. Remove any dead or yellowing foliage as it appears.

Pruning can also be done after flowering to tidy up the plant.

Propagate Commelina erecta from seed, stem cuttings, or division of clumps. Seeds can be sown in spring. Stem cuttings root easily in moist soil or water.

Division is best done in spring, separating the rhizomatous roots into smaller sections.

Repot your whitemouth dayflower every 2-3 years or when it becomes root-bound. Use a well-draining potting mix. Choose a pot that is only slightly larger than the current one.

Repot in spring, just as new growth begins to emerge, to minimize stress.
