watering

Prairie junegrass (Koeleria macrantha) is a drought-tolerant plant, so it does not need a lot of water to thrive. However, during periods of extended drought or excessive heat, Prairie junegrass should be watered deeply and regularly to ensure its health and vitality. The best approach is to fully soak the soil with water once or twice a week for about 20 minutes. Avoid overhead watering, as it can promote the spread of disease and mildew. During periods of extreme heat, watering twice a week can be beneficial. Be sure to check the soil before watering even if it is a regular watering day. If the soil is still wet, there is no need to water.

sunlight

Prairie junegrass (Koeleria macrantha) typically requires 6 or more hours of direct sunlight per day. For optimal growth, it should receive full sun in the morning, with shade during the hottest part of the day. It should also benefit from some light shade and cooler temperatures in the late afternoon to early evening. During the spring and summer months, Prairie junegrass should receive more hours of sunlight a day, while during the fall and winter months, it should receive fewer hours.

pruning

Prairie junegrass (Koeleria macrantha) should be pruned once a year, typically in late spring. Pruning should involve removing any dead or diseased stems and blades to allow for new growth and also to help maintain a desirable size and shape. When pruning, make sure to only take off up to a third of the grass’ leaves and blades at a time. Doing so will promote a lush, healthy growth of the junegrass and also help to prevent diseases or pests from taking hold.
