What are the Purple Flowers in My Yard?

A Tulsa lawn with purple flowers in it.

It appears that winter is giving up its grip, and spring is starting to take hold here in Tulsa. Temperatures are moderating. Trees are beginning to bloom and leaf out. Fescue lawns are getting to be a darker green. And all around town, you can see the blooms of henbit turning area lawns purple.

Henbit, an annual winter weed, is a member of the mint family. If you rub the stem of these purple flowers between your fingers, you will find that it has a square-shaped stem and minty smell. Left untreated and un-mowed, these weeds can grow 12 inches or taller, while producing many purple flowers. Like all weeds, henbit competes with the healthy turf for resources in the soil and can leave your lawn in pretty bad shape.

The best means of control for these purple flowers, and other winter annual weeds, is to apply a fall pre-emergent weed control. The fall application will provide a layer of protection in your soil that will not allow weed seeds to grow into difficult to control plants. However, if you missed the fall pre-emergent, these winter annuals can be controlled with a post-emergent.

Post-emergent weed control in the spring can be a little slow in the killing process, mainly due to cooler temperatures. While the plant will absorb the post-emergent and the weeds will begin to die, the process can take several weeks. The best thing you as a homeowner can do is mow the weeds down within five to seven days of our application. This will speed up the decomposition process and help your lawn begin the process of looking better quicker.
