Crimson fountain grass (Cenchrus setaceus)
Also known as: Rose fountain grass
Crimson fountain grass (Cenchrus setaceus), also known simply as fountain grass, is an ornamental plant originally from East Africa, Asia, and the Middle East. It is well-regarded for its drought tolerance and attractive burgundy plumes. However, it poses ecological concerns as it can be highly invasive, outcompeting native flora and increasing fire risk. Its ability to spread rapidly makes it a problematic species in some regions.

What Is the Ideal Temperature Range for Crimson fountain grass?
The ideal temperature range for Cenchrus setaceus, also known as fountain grass, falls between 65°F and 85°F. This temperature range ensures optimal growth by providing an environment similar to its native habitats. Keeping within this range helps the plant to sustain photosynthesis and maintain healthy foliage.
What Soil is Best for Crimson fountain grass?
Cenchrus setaceus thrives in well-drained soil, preventing waterlogging that can lead to root rot. This characteristic helps maintain optimal root aeration and nutrient absorption, ensuring healthy plant development. This plant is adapted to nutrient-poor soils, reducing the need for frequent fertilization. Such conditions allow it to compete successfully against less drought-tolerant species in arid and disrupted landscapes. The ability to tolerate dry soils makes Cenchrus setaceus an excellent choice for xeriscaping. This drought tolerance is beneficial in regions with limited water availability, promoting water conservation in landscaping.
How to Fertilize Crimson fountain grass?
For Cenchrus setaceus, also known as fountain grass, the recommended fertilizer amount is moderate. Use a balanced 10-10-10 liquid fertilizer, applying approximately 1 tablespoon per gallon of water. Apply evenly over the root zone to ensure nutrients reach the plant efficiently. Adjust if necessary, depending on plant growth and soil conditions.
How to Prune Crimson fountain grass?
Inspect the plant for any dead or brown stems throughout the year. Use your pruning shears to make cuts at the base of these stems to encourage new growth. To maintain a neat appearance, trim back any excessively long or unruly stems to just above a node, encouraging the plant to grow back fuller and more compact. Cenchrus setaceus can spread vigorously. Use scissors or shears to gently shape the plant to your liking, maintaining a balanced look by evenly removing parts across the plant. Gather all the removed debris and dispose of it away from the garden area to reduce the risk of spreading any plant diseases or unwanted seeds.
How to Propagate Crimson fountain grass plant?
1
Collect seeds from mature Cenchrus setaceus plants and clean them of any attached debris. Soak the seeds in water for 24 hours to enhance the germination process by ensuring they are adequately hydrated.
2
Fill propagation trays with a well-draining potting mix and plant the seeds at a depth of about half an inch. Ensure they are evenly spaced to allow sufficient room for development. Water gently after sowing.
3
For division propagation, carefully dig up a mature Cenchrus setaceus plant and gently separate the roots into smaller clumps. Each clump should have a good portion of roots attached to ensure successful replanting.
How to Repot Crimson fountain grass plant?
1
Repot when roots outgrow the current pot or when growth becomes stunted, often indicated by wilting leaves or poor soil draining. Spring and summer offer optimal conditions with active growth and recovery capabilities.
2
Select a pot slightly larger than the current one, with ample drainage holes to prevent waterlogging. This facilitates root growth and prevents root rot, ensuring healthy air circulation for optimal plant health.
3
Opt for a sandy, well-draining soil mix to mimic its natural habitat. Such soil prevents water retention that can lead to root rot, providing a stable and nourishing environment.
