I've applied a corn gluten pre-emergent to my lawn. I plan to continue to do so twice a year.
Using a puller, I'd like to manually remove the dandelions that are appearing, but pre-emergents stop working when the ground is disturbed.
Because of that, will removing the dandelions short-term & disturbing the soil cause more long-term problems? I want to do whatever will result in the fewest dandelions in the long-term.
