• This is to clean up prior to the new flush of growth that appears in the spring.
• It is not troubled by pests or diseases.
• Spear grasses grow on a wide range of soil types.
• These species grow well on poor soils.
• They also prefer soils that have high acidity.
• Tall Spear grass grows well in loam soils which have moderate to low pH.
• These species are high drought resistance.
Other tolerances of these species are:
– Low fertility tolerant
– Acid soil tolerant
– Frost tolerant

• The seeds should be sown below 5-10 mm of the soil surface when there is availability of moisture.
• Spear grass grows well when sown during autumn or winter.
