Wagnon is a grass that does not require regular pruning, as it is usually grazed or harvested as needed. However, if you want to maintain a particular shape or height, you can prune the grass using the following methods:

• Use a lawn mower or trimmer to cut the grass to the desired height, but avoid cutting too close to the ground, as this can damage the roots and stunt growth.
• Prune the grass in the early spring before new growth appears, rather than in the fall, to avoid damaging the new growth.
• Avoid pruning the grass during periods of drought or high temperatures, as this can stress the plant and make it more susceptible to disease and pests.

Propagation of Bromus inermis Leyss. ssp. pumpellianus (Scribn.) Wagnon var. arcticus (Shear ex Scribn. & Merr.) Wagnon

Bromus inermis Leyss. ssp. pumpellianus (Scribn.) Wagnon var. arcticus (Shear ex Scribn. & Merr.) Wagnon, also known as Arctic Brome, can be propagated through different methods.

Seed Propagation

Arctic Brome can be propagated by seed. Seeds can be collected from the plant when the seed heads have turned brown and have dried out. The collected seeds can be sown in a prepared seedbed and covered lightly with soil. It is important to ensure that the seedbed remains moist, but not waterlogged, as Arctic Brome requires a moist environment to germinate.

Division Propagation

Propagation of Arctic Brome can also be done through division. This is typically done during the spring or fall when the plant is not actively growing. The clump of the plant can be carefully dug up and separated into smaller sections. Each section can be planted in a new location and watered well.

Transplanting

Arctic Brome can also be propagated through transplantation. This method involves digging up an established plant and moving it to a new location. Transplantation is typically done during the fall or spring when the plant is not actively growing to reduce stress. It is important to water the plant well after transplanting.
