This guide focuses on common South Dakota cool-season grasses – grasses that utilize the C3 photosynthetic pathway. Cool-season grasses have an optimum temperature range of 65-75°F for the most active growth. Growth typically starts when the soil temperature reaches 40-45°F.
To consistently produce grass seed of any species the most important first step is to obtain a uniform, clean stand of grass. Skips and thin spots in the row invite weeds and other competing species which will cause trouble later. Weeds must be controlled the year of seeding and in subsequent years. However, careful
This guide focuses on common South Dakota warm-season grasses – grasses that utilize the highly eficient C4 photosynthetic pathway. Warm-season grasses have an optimum temperature range of 90-95°F for active growth, with growth starting when the soil temperature reaches 60-65°F.
Spanish needles occur in many different habitats, ranging from moist fertile soil to dry and infertile soil and sandy soils. They are most often found in moderately dry, full-sun areas that have been disturbed by human or animal activity.
Warm-season grasses produce most or all of their growth during the late spring to early fall period. This publication will concentrate on selected cool-season grasses, listing the most pertinent releases adapted to the Northern Plains. Selection of the proper species and variety is an important step when choosing a grass seeding mixture.
