Poa annua, otherwise known as annual bluegrass, is an annual grass that usually spreads by seeds. It has bright green colored leaves with a fine texture and a tufted look. It grows in a variety of conditions but moist and compacted soil suit the weed the best. Well irrigated turfs and a good rainfall can be really inviting to this weed. It also thrives in a range of light conditions from partial shade to full sun. One of the problems with this weed is the fact that it can produce seeds throughout its lifecycle with the majority of the seeds appearing early in the spring. Once your lawn is infected with even a few of these plants, the spread can be really rapid as mowing, birds and foot traffic all can lead to spreading the seeds far and wide throughout your lawn. If left unattended, this weed can completely take over your lawn in a matter of weeks.

If you do not take the proper care, well, they do spread like weeds and soon take over your precious green patch of heaven!
