Fall Lawn Guide Thread

Pre emergent is a preventer, it prevents weeds from germinating., it will not do anything to existing weeds you need to either pull them or spray with round up (non selective) or weed b gone type product (selective). Right now is a good time to put out a pre emergent as it will keep winter weeds down and make spring clean up much easier, I use fertilome product with dimension, I use it on the lawn and in flower beds, I will add another application to the flower beds in spring

I do not use any fertilizer or winterizer in the fall, and very little in the spring

Good thread. I need some direction myself. Is it too late to apply something like weed b gone before I do a pre-emergent?

Without knowing what turf grass you have, I'll just say that I use Simazine in my home lawn of centipede, and Specticle in the Bermuda turf at work. Both applied around 1st or 2nd week in Nov.

Control Options for Troublesome Weeds in Home Lawns

My method is to winterize before the grass goes dormant in the fall with a ferti-Lome granular that contains preemergent. Then I will follow the lsuag chart posted above to treat specific weeds I am having problems with. The weed free Zone is a solid product to put down in late fall as winter weeds begin to emerge.
Although some weeds like Virginia buttonweed will usually survive the weed free Zone treatment.

In the spring I apply a lawn fertilizer along with a broadleaf killer such as weed free Zone. Additionally, if there are problem weeds, usually sedge, I will again use the lsu chart to fight them back during the early stages before they are established.

PRE-EMERGENT
Does it help with existing weeds

Come on maaaann. Context clues.

Oh no!!! Please forgive me!!
Some weeds are dormant during the winter and I didn't know if pre-emergent meant that it would also help before they became active in the spring also. Thus the reason for the thread. Thanks for contributing.
