More weed questions- the lawn type

[elsid76]

Extreme North Georgia and in the hills/woods. Lawn is mostly Fescue so can’t use some of the harsher chemicals. Major problems with Dallisgrass and VA buttonweed. Lawn sprayer guy says he cannot do anything with Dallisgrass except suggest local kill with roundup and then remove plant and reseed the spot. Doing that but also tryin to remove them live before they get big. Major pain. For Buttonweed he can slow it down so again aggressively hand pulling.

You guys who know about this stuff have any suggestions?

Thanks and Go Bulldogs
