Napier grass requires consistent moisture, especially during its establishment phase and active growth. Water deeply once or twice a week, allowing the soil to dry slightly between waterings.

Reduce watering frequency during cooler periods or when the plant is dormant to prevent waterlogging.

Prune Napier grass severely at the end of the growing season or in early spring before new growth emerges. Cut back stems to about 10-15 cm from the ground.

This encourages vigorous new shoot development and maintains plant health. Remove any dead or damaged foliage as needed.

Napier grass is easily propagated vegetatively. Stem cuttings, typically 30-45 cm long, are the most common method. Plant the cuttings directly into prepared soil or a nursery bed, ensuring at least two nodes are buried.

Rooting is generally rapid under warm, moist conditions.

Repotting is generally not applicable as Napier grass is a large, clumping perennial grass often grown in the ground or in very large containers. If grown in a container, division every 2-3 years during the dormant season is the typical method of rejuvenation and management.
