Species Arctic Bentgrass

Arctic Bentgrass

Agrostis mertensii

Also Known As - Northern Bentgrass,Alaska Bentgrass
Arctic Bentgrass (Agrostis mertensii) is an evergreen cool-season grass found across Alaska and northern Canada. The grass loves cool-weather and can tolerate low temperatures, so it grows best in the arctic. Arctic Bentgrass has a low, creeping grow habit and its bright green foliage creates dense mats of foliage. Its small seed heads are very narrow and the seeds are relatively small. This hearty species is very hardy and can recover from extreme cold temperatures and drought. It can even be used as an ornamental grass in landscaping. Arctic Bentgrass is also edible and can be eaten raw or cooked. The leaves are not very palatable in large amounts but can add a bit of flavor to salads and soups.

watering

Arctic bentgrass (Agrostis mertensii) should be watered 2 to 3 times a week, depending on the soil type and ambient temperature. During times of low rainfall or high temperatures, it may need to be watered more frequently. For this species, watering should occur once every 2 to 3 days in sandy soils and more often in heavier soils such as clays. When watering, ensure that the soil is thoroughly soaked, but be careful not to overwater as this species is very susceptible to waterlogging and root rot. Additionally, avoid watering in the evening or during the heat of the day as this can lead to leaf scorch or other damage.

sunlight

Arctic Bentgrass (Agrostis mertensii) typically prefers full sun to partial shade, but can tolerate full shade conditions. It needs at least 8 hours of sunlight per day in order to thrive. In the summer months, sunlight should be available from 10 a.m. to 4 p.m., and in the winter months, from 11 a.m. to 3 p.m. On gray or cloudy days, it should receive 4 to 6 hours of direct sunlight. It is important to keep out of direct midday sun during the summer months, as to avoid sunburn and wilting.

pruning

Arctic Bentgrass (Agrostis mertensii) should be pruned during the early spring months, just before new growth begins. If there is a lot of old growth that needs to be removed, it is best to do it in 2 stages. Pruning should be done lightly to avoid damaging the grass. In the first stage, prune off the excess old growth and damaged turf to reduce the risk of disease and to promote new growth. Then, in the second stage, prune the tips of the remaining foliage to thin out the growth and improve air circulation. This will help to reduce instances of disease and also to promote thicker growth. Pruning frequency should be kept to a minimum and should generally be done only once or twice a season.
