Growing/Caring conditions

• Stipa species and cultivars are all easily grown in any moderately fertile, well-drained soil in full sun.
• Most are hardy to at least -15°C.
• Though many will not survive the winter conditions where the soil is waterlogged.
• Plants should establish quickly.
• Once growing well they need little attention apart from cutting back of the foliage during the winter.
• 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.
• In the cooler months, germination can take from 6–8 weeks.
• In the warmer months, it may be 7–10 days.
• Keep the soil moist.
• Do not water log the soil for three weeks after sowing.
• Sowing of seeds can be done with or without awns.
• Sow the seeds with awn so that they are able to move during watering.
• This will help the awn to find a space for its burial.
• It is more difficult to sow this way.
• It generally requires hand sowing.
• Sowing the seeds without awns is easier.
• It requires sowing into a groove or shallow trench.
