Pre-Fall Lawn Tips

(Updated: Sept. 13, 2021, 12:36 p.m.)

It has been almost two weeks since I've been able to mow my lawn. I’m sure the neighbors think I’ve gone crazy. The seed heads for the grass have gotten so tall they are almost double the height of the actual lawn. I’m going to have to raise the mower deck one more notch when I do mow, so I don’t remove more than 1/3 of the leaf blade. I may be out mowing the lawn every 3 or 4 days until I can get the lawn back to the height, I like it maintained. With this, it’s time to put into practice what I have been writing about for so long.

As thick as the lawn looks out there right now, it’s hard to imagine any weed seed would be germinating, but now is the time to consider applying a pre-emergent herbicide for those winter annual weeds like hop clover and vetch that I have such a bumper crop of every winter. Maybe this year the lawn is thick enough that there won’t be any weeds.

Now is also the time for applying fungicides to control large patch disease in centipede and St. Augustine grass lawns. To this point, I haven’t had any problems with this disease in my yard. For those who have had problems, now is the time to make those fungicide applications as a preventative measure. I only recommend this to those who have had a big problem with large patch disease in the past. If you haven’t had the disease, then there is no need to treat.
