How to Grow Mountain Brome


Mountain brome is a grass common in the Rocky Mountains and the mountainous Pacific Coast regions. It prefers the sun, but can tolerate some shade. It grows to be about 4 feet tall and is generally used for livestock to graze and as erosion control. Mountain brome seeds are often mixed with other seeds to create a balanced diet for grazing animals.

Step 1

Prepare the soil bed. Mountain brome can tolerate almost all soil conditions. Add some compost or other organic matter to areas with high clay or other hard soil contents. Weed and till the area about 1 inch deep. Avoid areas with high water tables and where flooding is likely.

Step 2

Rake in or spread the mountain brome seeds about 1/2 inch deep and water. For spring plantings, this should be done by mid-May in lower elevations (foothills) and before the first of June in high elevations (mountains). For fall plantings, seed starting in late October. Generally, planting five to ten pounds of seeds per acre is normal. Even more seeds is needed if planting for erosion control and less is needed if mixing in with other seeds.

Step 3

Continue to weed the area during the first year when plants are still getting established. If possible, do not let animals graze on mountain brome the first year. Keep the area moist for about 2 weeks while the seeds are germinating. Thereafter, soil should be moist during the growing season, which typically occurs during late spring and through the summer months.
