Mozambique signalgrass Plant Care

Mozambique signalgrass (Urochloa mosambicensis) belongs to the Poaceae family within the Urochloa genus. Mozambique signalgrass is native to tropical and southern parts of Africa, Arabian Peninsula and western Madagascar. Mozambique signalgrass is also known as Red signalgrass.

Mozambique signalgrass displays a tall, spreading grass growth habit, reaching up to 6 ft tall with a spread of approximately 4 ft. Mozambique signalgrass produces inconspicuous flowers in spikelets.

Leaf size: approximately 12 inches.

Urochloa mosambicensis requires watering every 7–14 days. Allow the top layer of soil to dry between waterings to prevent root rot. Reduce watering frequency during winter when growth slows.

Mozambique signalgrass thrives in full sun to partial shade.

Urochloa mosambicensis grows best at temperatures of 65–85°F. Mozambique signalgrass prefers humidity levels of 40–70%.

Well-draining sandy loam with good fertility. Good drainage is essential for Mozambique signalgrass to prevent waterlogging, which leads to root rot and fungal issues.

Feed Mozambique signalgrass every 8 months during the growing season (spring and summer) with a balanced fertilizer diluted to the strength on the label.

Pause feeding in autumn and winter, when growth slows, and never fertilize dry soil — water first.

The PlantoScan app can remind you when to water and when to fertilize each plant.

Divide and repot every 2-3 years in early spring. Choose a pot one size larger than the current container, and ensure it has drainage holes to allow excess water to escape.

Mozambique signalgrass can be propagated through seeds, division of clumps. Similar propagation techniques also apply to signal grass plant care, which shares the same genus.
