Redleg Grass Care (Bothriochloa macra)

This warm-season grass prefers full sun but tolerates some light shade in hot regions.

• Provide 6–8 hours of direct sun daily; morning sun with light afternoon shade reduces summer stress in hot inland areas.
• In partial shade (3–4 hours sun), expect looser growth and less intense color, but Redleg Grass generally maintains acceptable vigor.
• Avoid deep shade or dense competition from shrubs and trees, which leads to weak, floppy stems and sparse patches over several seasons.

This species prefers moderately dry conditions and performs best in well-drained soil.

• Allow the top 3–5 cm of soil to dry between waterings; soil should feel dry but not powdery before adding water.
• In the first growing season, water deeply when blades curl, lose sheen, or footprinting remains, then reduce frequency once Bothriochloa macra is established.
• Watch for yellowing bases and soft, rotting crowns as signs of overwatering, and crisp brown leaf tips and slow recovery after mowing as signs of underwatering.

This warm-season grass grows best in mild to hot weather and slows in cool conditions.

• Optimal active growth occurs around 75–90°F (24–32°C); growth rate drops noticeably below 65°F (18°C).
• Established plants tolerate summer heat up to about 100°F (38°C) if soil is not waterlogged and there is occasional deep watering during drought.
• The grass survives short dips to about 20–25°F (-6 to -4°C) but foliage burns with hard frost, so expect seasonal browning and regrowth from the base in spring.

This species tolerates a broad humidity range and does not usually need special humidity management.

This warm-season grass prefers lean, well-drained mineral soils and copes well with low fertility.

• Use sandy or sandy-loam soil with low to moderate organic matter to mimic natural grassland conditions for Bothriochloa macra.
• Ensure very sharp drainage; incorporate coarse sand or fine gravel to prevent prolonged saturation around the roots.
• Aim for slightly acidic to neutral pH around 6.0–7.5, avoiding highly acidic or saline soils that limit root function.
• Avoid heavy, compacted clay; if unavoidable, lighten it with coarse sand and fine gravel to improve aeration and water movement.

This species can be grown in containers, mainly for ornamental or trial plantings rather than long-term, dense clumps.

• Choose a wide, low container to accommodate its fibrous, spreading root system and reduce the risk of tipping in wind.
• Use a gritty mix of sandy loam and coarse mineral material so water drains quickly after irrigation or rain.
• Select a heavier pot material such as ceramic or concrete in exposed sites to stabilize the plant’s airy top growth against gusts.

Bothriochloa macra is a tough, low-input grass that benefits from light feeding only on poor soils.

• Use a balanced slow-release fertilizer (for example 10-10-10) or a thin layer of compost in spring.
• Feed once at the start of the growing season; avoid multiple applications in fertile ground.
• Apply at half the label rate to prevent lush, floppy growth and nutrient runoff.
• Skip fertilizing in winter or dormancy, as nutrient uptake is minimal then.

Bothriochloa macra needs only modest pruning to stay tidy and encourage fresh growth.

• Cut back spent flower stems and dead foliage in late winter or very early spring before new shoots emerge.
• Remove damaged, diseased, or badly lodged clumps with clean, sharp shears.
• Thin crowded patches by taking out entire small clumps to maintain airflow and an even appearance.
• Light annual cutting keeps the grass compact and supports healthy new tiller formation.

This grass is usually grown in the ground, so management focuses on dividing and transplanting mature clumps.

• Transplant or divide in early spring or early fall when temperatures are mild and soil moisture is reliable.
• Look for crowded clumps, dead centers, or slow growth as signs that Bothriochloa macra needs lifting and division.
• Split clumps into smaller sections with a sharp spade, keeping generous roots and firm soil attached to each piece.
• Replant at the original soil depth, water thoroughly, and shade temporarily if needed to reduce transplant shock.

Bothriochloa macra is commonly propagated by division and by seed for meadow and lawn-style plantings.

• Divide healthy clumps in early spring or early fall, when soil is moist and temperatures mild.
• Cut clumps into several pieces, each with strong shoots and roots, then replant promptly and water well.
• Sow seeds in late winter to spring on well-drained soil, barely covering them, and keep evenly moist until germination.
• Provide full sun and avoid waterlogging to support strong root development in new plants.

This species is generally cold hardy in temperate climates and usually needs minimal winter care.

• In colder regions, allow dry foliage of Bothriochloa macra to stand over winter to shelter crowns.
• Apply a light mulch layer around the base in late fall where winters are severe or very dry.
• For container-grown plants in cold zones, move pots to a sheltered, unheated but frost-moderated spot.
