finestem needlegrass

Nassella tenuissima

Finestem needlegrass (Nassella tenuissima) is native to North America and is a perennial bunch grass common in mesic grasslands. It has delicate, fine-textured, curved blue-green blades that arch at the ends and can grow to be 16-24 inches tall. From mid-summer to fall, showy inflorescences of purplish-red spikelets appear, adding intriguing visual interest to the landscape. Finestem needlegrass is tough enough to tolerate drought, and its flexible and strong roots help it survive flooding as well. It's a great species to add to anybeautiful, low-maintenance residential or commercial landscape.

watering

Nassella tenuissima (Finestem Needlegrass) should be watered deeply at least twice every month. Water until the soil is damp, but not soggy. Make sure not to over-water, as this can cause root rot. Signs that the plant may not be getting enough water include wilting and/or yellowing of the leaves, or a decrease in the amount of growth. It is important to water the plant consistently to ensure that it is getting sufficient water. You can also check the soil for moisture level to determine if it needs to be watered.

sunlight

Finestem needlegrass (Nassella tenuissima) needs a direct and uninterrupted light source to do its best. This species of grass does best in full sun with a minimum of at least 4-5 hours of direct sunlight a day, optimally 6-8 hours. It is recommended not to expose your finestem needlegrass to any shade or indirect light as this can cause it to become/stay stunted and tend to dry out too quickly.

pruning

Pruning for Finestem Needlegrass (Nassella tenuissima) is not necessary as the grass does not respond to pruning. It will still produce new, healthy blades after old blades have died back in the winter months. If there are areas of the Finestem Needlegrass that are more dense or contain dead or damaged blades, they can be removed by hand. It is important to time any pruning activity so that it coincides with the grass's dormancy period, which usually occurs in the late fall and winter months. Pruning during this period will help to limit diseases and shock to the plant as the plant is no longer actively growing. It is important to never prune more than 1-third of the total live blades of the grass. Pruning too aggressively will decrease the grass's overall health, vigour and productivity.
