Grass Plant Structure and Growth - Growth Cycle of a Cool Season Grass Plant
Figure 3.3 illustrates the general growth cycle differences between these two grass types. Note that the cool season grasses have growth peaks in the spring and fall, indicating a response to the cooler conditions at those times of the year. The warm season grasses have a peak growth period during the summer months, providing ample water is present, indicating their response to the warmer conditions.
Annual weedy grasses, such as crabgrass and foxtail, also follow the warm season growth curve. In the case of crabgrass or foxtail, they begin their life cycle from seed while perennial warm season grasses, such as Bermuda grass, begin growth from existing plant structures.
