Crabgrass Killer: What It Is And Best Time To Apply


Crabgrass Killer

Crabgrass Killer is a great way to get rid of stubborn crabgrass without causing too much damage to your lawn.

Applying it during the morning dew or on a wet area will ensure the weed is killed and the rest of your lawn remains healthy and beautiful.

Apply the product evenly, and wear protective gear when working around water.

Crabgrass is an annual grass weed that overwinters in the soil. It germinates in mid-May or later and is killed by the first frost. The plant thrives in heat and drought and will take over where the grass is thin.

Your best defense is to aim for a thick, vigorously growing lawn. This will not only discourage crabgrass but other lawn weeds from getting established.

In early spring, detach and aerate your lawn. Give your lawn a vigorous raking to remove winter debris, and use a coring or spiking machine. These machines allow air, water, and fertilizer to penetrate the roots.

The lawn should be fertilized twice a year – once in the spring and once in the fall. Top dress (add soil, compost) to the lawn where necessary and overseed with a grass mixture of Kentucky Bluegrass, perennial Rye, and Creeping Red Fescue.

When watering, water deeply once a week in the morning for at least an hour. The grass will have a chance to dry before evening. This helps to prevent fungus and disease.

Use a sharp lawn mower and cut the lawn at least two to 21/2 inches in the summer. The more extended height keeps the grass roots cool, conserves moisture, and helps to shade out weed seedlings.

When To Apply Crabgrass Killer

As the soil warms, crabgrass seeds begin to germinate. In general, seeds germinate between 60°F and 70°F when the ground reaches 55°F.

Soil temperatures are primarily influenced by sunlight, wind, moisture, and shade.

During the springtime in the Midwest, soil reaches these temperatures with the onset of warmer temperatures.

As a result, 55°F is the optimal soil temperature for applying your weed treatment.

For maximum efficiency, you must apply crabgrass preventer to your lawn at precisely the right time.

When used too early, it can break down before the seeds germinate. Using this method too late could result in a full-blown infestation.

If possible, apply a crabgrass preventer before rain is forecast, keeping an eye on the soil temperature.

In the rain, the crabgrass seeds and the treatment will be washed into the soil.

How to Apply Crabgrass Preventer

If you’re wondering how to prevent crabgrass, the best thing you can do is to put down a preventer before the crabgrass seeds sprout.

Crabgrass preventer is a pre-emergent herbicide instead of a post-emergent herbicide, so you’re already a few steps ahead if you apply early in the spring.
