New England Northern Reed Grass

Calamagrostis stricta subsp. inexpansa

Also Known As - Western Bluejoint,Northern Grass
New England Northern Reed Grass is a perennial cereal grass native to North America. Its grassy blades are dark green and upright in form, reaching an average height of four to five feet upon maturity. Its feathery, silvery flower spikes turn reddish-tan in the fall and are highly attractive to birds. This vigorous species prefers wet soils and is an excellent choice for wetland restoration projects in the northern United States. Because it sets deep roots, it is well-suited for erosion control and soil stabilization, and is also highly effective in creating wildlife habitat. With its ability to survive in moist and shady conditions, New England Northern Reed Grass is a worthwhile consideration for any garden.

watering

New England Northern Reed Grass (Calamagrostis stricta subsp. inexpansa) should be watered 1-2 times a week, depending on the weather. During hot, dry weather or during times of extreme drought, it may need to be watered more frequently; in cooler climates, less often. Make sure to keep the soil evenly moist, but never leave the soil soggy or waterlogged. In spring and summer, 1/2 inch of water applied to the root zone of the plants is usually enough. In fall and winter, reduce the water to 1/4 inch. To ensure that the plants receive enough water, create basins around the plants and slowly pour water into the basins until the soil is moist.

sunlight

New England Northern Reed Grass, or Calamagrostis stricta subsp. inexpansa, grows best in full sunlight, with at least 6 hours of direct sunlight each day. The best time of day for the grass to receive ideal sunlight is between the hours of 9:00 a.m. and 3:00 p.m. During the summer months when the days are longest, the grass should be exposed to daylight for the majority of the day. In the winter months, when days are typically shorter, plants should receive at least 4 hours of sunlight each day in order to develop and remain healthy.

pruning

New England Northern Reed Grass should be pruned annually in late winter or early spring before active growth starts. Pruning should not exceed a third of the total plant height. Start by removing dead or damaged stems and any flowers or seed heads that are present. If the grass is particularly crowded, reduce the overall size by selectively removing stems here and there. Flowwering stalks can be removed and the seed heads can be collected for propagation. For more drastic pruning, such as when establishing a beautiful and lush shape, wait until the late fall when the grass has gone dormant and prune back the stems to a uniform height of 6-10 inches. Pruning should be repeated in this fashion about once every 3 years to ensure the grass maintains a neat and tidy appearance.
