Crabgrass is a high-quality summer annual forage grass that is well adapted to Florida’s sandy soils. While considered an invasive weed in lawns and agriculture, it is a valuable summer forage crop, and can be used in a rotation as pasture for livestock grazing or hay production.
Crabgrass seeds sprout in spring and summer. Although the flower head is similar in appearance to the flower head of Bermuda Grass, the spike-like flower branches of crabgrass grow separately from the stem, whereas those of bermudagrass radiate from the same point.
