DETAILS
Care Instructions
Needlegrass prefers full sun and can tolerate a range of temperatures, though it thrives in temperate climates. It requires moderate watering, allowing the soil to dry out almost completely between waterings. This plant does well in moderate humidity and does not require frequent fertilization.Soil
Needlegrass prefers well-draining loam soil but can adapt to other soil types. It is important to ensure good drainage to prevent root rot. The soil should be allowed to dry out between waterings to mimic its natural habitat.Fertilizer
This plant does not have high fertilizer requirements. If desired, a balanced, slow-release fertilizer can be applied sparingly during the growing season to support healthy growth.Repotting
Repotting is generally not necessary for needlegrass, as it is typically grown outdoors. However, if grown in a container, repotting can be done every few years to refresh the soil and provide more space for root growth.Propagation
Needlegrass can be propagated by division. The best time to divide the plant is in early spring or late fall. Carefully separate the clumps and replant them in well-prepared soil.Pruning
Pruning is not required for needlegrass. However, removing dead or damaged leaves can help maintain its appearance and promote healthy growth.Toxicity
Achnatherum calamagrostis is not known to be toxic to pets or humans. It is generally considered safe to grow in gardens and landscapes.REVOLUTIONIZE YOUR PLANT CARE
