watering

Reporting from the National Arboretum, One and a Half Flowered Reedgrass (Calamagrostis sesquiflora) should be watered every 7-10 days in the hot summer months and every 2 weeks during the cooler months. Water enough to thoroughly moisten the soil, but stop when it begins to pool at the surface.

sunlight

Calamagrostis sesquiflora, or One And A Half Flowered Reedgrass, is a plant species that generally requires full sun in order to thrive. For optimal health and growth, this species should have at least 6-8 hours of direct sunlight each day. It is best to give this plant as much sunlight as possible during peak sunlight hours, which is usually from mid-morning until mid-afternoon. In the winter months, however, it is preferable to provide the plant with as much direct sunlight as possible.

pruning

When it comes to pruning One and a Half Flowered Reedgrass, the best time to prune is when the plant is actively growing in the spring and summer months. Pruning should be done when the grass has reached your desired height, width, or shape. Depending on the growth amount, it might need to be trimmed up to 3 times per season. Prune with sterile pruners as close to the ground as possible, taking off no more than 1-third of the top growth at a time to prevent shock to the plant. Make sure the blade of the pruners is sharp so that the cuts are clean and reduce the risk of the grass becoming infected. If pruning to control the width and height, focus on pruning the oldest stems first. Never trim below 2 inches — this will cause undue stress to the plant.
