Click an image to see it above:. Hairy Grama Grass Bouteloua hirsuita is a small-growing native grass that thrives in poor soils and blooms in summer with cheery eyelash-like flowers. This xeric plant is an excellent addition to waterwise gardens, for groundcover and textural accents that provide visual interest year-round.
It will reseed and naturalize over time, but is not appetizing to deer. If you live in very warm winter areas zones plants with zones ratings are not recommended.
The lack of freezing winter temperatures do not provide a time for winter dormancy rest. Look Up Zone. In stock. SKU HC Add to Cart. Add to Compare. Skip to the end of the images gallery.

Use a pre-emergence herbicide in late winter or early spring to prevent germination of seed. These products often need rainfall or irrigation to activate them so time your application wisely.
Remove any plants that do germinate early in the season as it becomes more difficult at the roots take hold of the soil. Mulching garden beds can slow germination. It is killed off by frost.
In lawn situations, keep turfgrass as healthy as possible so it has a dense canopy that will outcompete Crabgrass. Vegetative growth slows and plants enter their reproductive stage. Purplish seed heads form until frost kills the plants. Plants that emerge early in the season and have a long period of vegetative growth are much larger and more competitive than plants that germinate late in the season. Crabgrass is found in almost every turf and landscape situation.
It is prolific in lawns, golf courses, athletic fields, gardens, orchards, and waste places. It thrives particularly well in lawn situations. Once established, crabgrass tolerates both high temperatures and dry weather conditions because of its physiological makeup.
Crabgrass species are often very competitive because they are C4 type warm season plants. C4 grasses thrive during the hot weather and abundant sunlight of the summer when cool season turfgrasses C3 plants are under stress. Crabgrass is very noticeable in lawns. It is a rapid growing, coarse textured yellowish-green grass that is conspicuous when found growing among fine textured, dark green cool season turfgrasses.
The stems are spreading and much branched. Roots develop at nodes on the prostrate stems. The first leaf is only about twice as long as it is wide. It is tinged light purple and has a white strip running down the center.
Both sides have silky, shiny hair. The leaf sheaths of large crabgrass seedlings are tinged purple and are covered with long stiff hairs. The ligule is large membranous, and toothed. A ligule is a thin membrane or row of hairs at the top of the junction of the leaf sheath and the leaf blade. Auricles are absent. Auricles are the appendages projecting around the stem from both sides of the collar.
The basic principle of a crabgrass management program is to prevent re-infestation by seeds. Controlling seed production for several years will help reduce the viable seed supply. Crabgrass cannot be controlled in one growing season because of the great number of viable seeds that accumulate in the soil from years of infestation.
A good weed management program in lawns is one that consists of both focused cultural practices and the use of herbicides as appropriate for the control of any given species. Satisfactory control may require several seasons of conscientious adherence to a good management program.
