Juncus inflexus thrives in consistently moist conditions. Water regularly to keep the soil saturated, especially during warmer months. Avoid allowing the soil to dry out completely, as this can stress the plant.

In drier climates or during heatwaves, increase watering frequency.

Prune Juncus inflexus in late winter or early spring before new growth begins. Cut back dead or damaged foliage to about 5-10 cm from the base.

This encourages vigorous new growth and maintains the plant's tidy appearance. Remove any brown or unsightly stems as needed.

Juncus inflexus can be propagated by division or from seed. Division is best done in spring, separating established clumps into smaller sections with roots and shoots.

Sow seeds in spring or autumn, keeping them moist and cool. Germination can be erratic from seed.

Repot Juncus inflexus when it becomes root-bound, typically every 2-3 years. This is best done in spring. Choose a pot that is only slightly larger than the current one. Use a well-draining, fertile potting mix.

Ensure the plant is watered thoroughly after repotting.
