For St. Augustine grass you can use organic crabgrass killers. Just do a google search and you'll find the products.
We live in North Florida and have about 40% of our St Augustime lawn covered with Crabgrass. I would be interested in finding a way to kill the crabgrass without destroying or damaging the St Augustine grass. I read about the vinegar solution and wondered if this would work. If so, what is the mixture ?
Alright, then what do you do? Spray it on the plant? water the plant ? And how often? If that works I'm going to do it. Does it work on all weeds or just crabgrass? thanks a bunch
1 gallon white vinegar . Add 8 drops of liquid dish washing detergent (helps plant material absorb the liquid)
