Finally, when the soil temperature hits 60° Fahrenheit for three days and the air temperature remains at 90° Fahrenheit, the seeds of dallisgrass start to germinate.

When a pre-emergent is used, they create a barrier between the seeds and the ground surface. This barrier Prevents the seeds from growing through it.

As a result, the roots die, and plants no longer grow from them.

Using a pre-emergent during the spring can help your lawn stay free from the dallisgrass for the rest of the year.
