Digitaria sanguinalis aka Common Crabgrass
Taxonomy
Digitaria sanguinalis, also known as Hairy Crabgrass, Large Crabgrass, Crab Finger Grass, and Purple Crabgrass, is a species of grass that is known worldwide as a common weed. It is a summer annual that can quickly spread and form colonies in full sun to part sun, preferring moist to dry clay loams. Although it is often considered a nuisance, it has some uses such as being used as animal fodder and having edible seeds that are sometimes cultivated as a grain in Germany and Poland where it is called Polish Millet. However, to prevent its spread, it is recommended to use a pre-emergence herbicide in late winter or early spring to prevent germination of seed, and professional application of a select crabgrass killer may be necessary.

Soil
When growing Common Crabgrass, it is important to pay attention to the soil type you are using. This plant is very sensitive to dry soil and needs a potting soil that retains moisture. A good soil should still be well-draining and contain lots of organic matter. Coco coir or sphagnum moss are great options to provide the Hairy Crabgrass with the nutrients and moisture it needs.

Lighting
Common Crabgrass requires abundant, bright and direct light. Placing it less than one foot from a window is the best way to make sure the plant receives enough light to survive and thrive. Depending on your region, however, the current weather can affect the placement of the plant in your home. For example, in some areas the sun may be too direct and intense, so it's best to place it farther away from the window. You may also need to adjust your placement according to the season as the sunlight can change intensity over the course of the year. If you live in a region with significant temperature fluctuations, such as a desert, you may need to place the plant a bit farther away from the window to avoid extreme heat or cold. With some care and attention, your Common Crabgrass will be sure to bring you many years of beauty and enjoyment.
Dormancy
During the cold period, it is common for Common Crabgrass to go dormant and their growth may slow down, so waterings should be spaced out more during this period.
