Narrow-Fruited WatercressNasturtium microphyllum

Maintain consistently moist soil, as Nasturtium microphyllum thrives in wet conditions. Water frequently, especially during warmer months or if grown in containers.

Avoid allowing the soil to dry out completely, as this can stress the plant and reduce its vigor. Ensure good drainage to prevent root rot.

Pruning is typically done to maintain shape, remove dead or damaged foliage, or to encourage bushier growth. Pinch back stem tips regularly during the growing season.

After flowering, you can cut back overgrown stems to promote a second flush of blooms and prevent excessive self-seeding if desired.

Nasturtium microphyllum is easily propagated by seed or stem cuttings. Sow seeds directly in moist soil after the last frost, or start them indoors a few weeks prior.

Stem cuttings can be taken in spring or summer and rooted in water or moist potting mix. Both methods generally yield good results.

Repotting is usually necessary when the plant becomes root-bound, typically every 1-2 years for container-grown specimens. Choose a pot that is slightly larger than the current one.

Repot in spring before active growth begins. Use a well-draining potting mix, but ensure it retains some moisture.
