What kind of soil does crabgrass like?
Herein, does crabgrass like acidic soil?
Crabgrass can give you some clues about your soil. Just like annual bluegrass, Carolina geranium and plantain, crabgrass grows well in acidic soil, usually with a pH of 4.8 or higher. But in about a month, the soil will warm to about 55 degrees which is the perfect temperature to make a seed grow.
Secondly, is it OK to pull crabgrass?
Spray postemergence herbicide directly on crabgrass after it has sprouted. Pulling is equally effective, but if the roots are deeply embedded in your lawn, it may be tough to pull them out without pulling grass chunks too. It's not worth spraying a postemergence product on crabgrass that has gone to seed.
Crabgrass is primarily an 'opportunistic' plant and will usually grow in thin or bare areas of your lawn, but it can also crowd-out good grasses that are weakened – sometimes by scalping the lawn (mowing too short), insect and disease activity or other problems.
