Yes, you should remove crabgrass from your lawn. The timing matters more than the method you choose. Getting plants out before July stops them from producing seeds. This breaks the cycle that keeps the weed coming back year after year. Every plant you pull or kill before it seeds saves you from fighting its offspring next spring.
I learned the value of early action through a frustrating mistake. One summer I decided to pull crabgrass from lawn areas in late August after the plants had grown thick. The pulling went fine, but those plants had already dropped thousands of seeds into my soil. The next spring, my crabgrass problem was worse than before. The following year I started pulling in June when plants were small. That fall, I had 80% less crabgrass than the season before. The timing made all the difference.
Rutgers research confirms that crabgrass won't regrow if you remove the entire crown at the base. This makes hand pulling effective when you get the whole root crown out. Grab the plant low at the base, twist, and pull firm. A garden knife helps loosen the roots in hard soil. Young plants come out clean with little lawn damage. Older plants leave bigger bare spots that you'll need to reseed in fall.
The numbers show why when to remove crabgrass sets your success level. A single mature plant puts out up to 150,000 seeds that fall into your soil. Those seeds survive for at least 3 years waiting to sprout. Pulling one plant in June before it makes seeds wipes out that entire future seed load. Waiting until August means most seeds are already in the ground. Even if you pull the plant at that point, the damage to your next year's lawn is done.
Your approach should match the size of your problem. If you count fewer than 20 plants across your lawn, hand pulling works great and costs you nothing. For 20-100 plants, a post-emergent herbicide like quinclorac saves you time and gives better coverage. If crabgrass fills large sections of your lawn, spraying alone won't fix the root cause. You need a pre-emergent plan for next spring plus fall overseeding to thicken your turf.
Your crabgrass removal timing should pair action now with prevention for next year. Pull or spray what you see today. Then overseed your bare spots in early fall so thick grass crowds out future seedlings. Apply a pre-emergent next spring before soil hits 55°F (12.8°C). This plan tackles your existing plants and the seed bank at the same time.
I also keep a small bucket with me when I mow during June and July. If I spot a crabgrass plant while cutting, I stop and pull it right there. This habit takes me an extra five minutes per mow but keeps my lawn clean without any spray. You'd be surprised how much of a difference catching plants early makes over a full season. Try it yourself this summer and you'll see the results by fall.
