Crabgrass Prevention Should Be a Part of Yearly Fort Wayne Lawn Care


Ugh! Crabgrass! No one with any sense of pride wants that clumpy, unsightly weed in their lawn. But grow it does in lawns all over Fort Wayne. And that’s too bad, because there are easy enough and inexpensive enough ways to keep it from growing. 

To get a bit more “technical,” crabgrass is what’s classified as an annual grass-type weed. That means it germinates each year from seed, then dies at the end of the growing season. Between birth and death, though, one crabgrass plant can produce thousands of seeds – as many as 150,000! So next year’s generation of plants is a done deal. Unless you can kill the seeds.

We’ll get to the most popular method of killing crabgrass seeds in a moment. Right now, let’s look at one of the best ways to keep crabgrass out of your lawn altogether. That would be to promote the vigorous growth of thick, dense turf in the first place. Crabgrass hates competition for nutrients. The thicker and healthier your lawn, the less chance crabgrass has to survive. Conversely, crabgrass thrives in poorly maintained lawns. Those are lawns that have sparse, diseased and deteriorating turf, get high foot traffic, are insect-infested, are kept cut too short, and are improperly fertilized.

To keep crabgrass at bay:

  • First make sure your lawn has the type of grass that grows best in your area.
  • Overseed or lay sod if you’re just starting a lawn.
  • Use grass plugs to fill in a lawn that’s sparse and patchy.
  • Mow your lawn to the highest cut recommended for your grass type: generally no lower than 3 inches to 3.5 inches. This helps shade the soil, which makes it harder for crabgrass seeds to germinate.
  • Water your lawn properly – at least once a week during periods of extended dry weather. Doing so also helps thwart crabgrass germination.
  • Avoid fertilizing your lawn in late Spring and Summer if crabgrass is already a problem. And when you do fertilize, don’t use high-phosphorous fertilizers. Yes, they help grass grow. But they also help crabgrass get a foothold too.

If you need to rid your lawn of crabgrass, the most popular and proven-effective way to do so is to use what’s called a preemergent herbicide.

Signature Lawn & Tree Services will apply a Spring preemergence control along with a fertilizer properly formulated for your lawn prior to crabgrass germination.

To be perfectly accurate, preemergent herbicides don’t prevent seeds from germinating. Seeds will germinate after a preemergent has been applied. What the preemergent actually does is prevent the cells of germinated seeds from dividing, which causes the seeds to die.
