Organic crabgrass killer options
After a few years of organic lawn care, i'm about ready to break down and try something else to kill my crabgrass. My back lawn now is about 25% crabgrass and I need to get this problem taken care of before it spreads further.
I'd love an option other than weed-b-gon and I did some extensive web searching and came up with these.
and here, baking soda is mentioned:
Does anyone have experience with any of these options? I suppose it's not the end of the world if I use one application of weed-b-gon, but I hate to abandon 3 years of organic-only lawn...
Thanks in advance for any help!
