Baking Soda on Crabgrass
I have tons of crabgrass in my P-77 Bermuda lawn.
I read that dusting crabgrass with baking soda is an effective way to kill crabgrass without hurting the lawn, somewhere I read that someone mixed the baking soda with hot water and sprayed it on the grass rather than "dusting" the powder, this would seem like the easiest way to go, can anyone confirm that this method works?
If not, could you just water the lawn so its all wet, then sprinkle baking soda over everything with a hand spreader or flour sifter?
How often would you need to repeat this to keep the crabgrass away and will this negatively affect the microherd?
