Crabgrass Weed Killer

Crabgrass, scientific name – Digitaria spp is a annual lawn weed that is native to warm and tropical areas. It is one of the most common weeds, so called because of its slender, fingerlike appearance. It can spread vigorously in hot and dry conditions. During the fall, a single weed can produce thousands of seeds which can then germinate fast in spring. Crabgrass can spread quickly if no precautionary measures are taken;meaning if you do not take care of your garden properly. There are however steps that you can do to kill crabgrass.

Knowing the life cycle of a crabgrass can help you identify which one is the best crabgrass weed killer. During summer and fall, the crabgrass produces seeds which can germinate thousands. The seed germinates around March in springtime when the temperature of the soil reaches 55-60 degrees Fahrenheit at a depth of around 2-3 inches. Even if the crabgrass gets killed by frost during winter, the seeds it produce can grow vigorously during spring when proper measures are not done to prevent it from spreading.

Based on its life cycle, the best way to get rid of crabgrass is by applying pre emergent weed killer at the right time, that is before the seed germinates. From summer to mid fall, crabgrass produces thousands of seeds. The best way to apply the herbicide is by mid March when the soil reaches the right temperature before the seeds start germinating.

Mowing your lawn at a higher height is another way for you to get rid of crabgrass. If your lawn is long, it tends to shade the crabgrass seed and prevent its germination. When you have a thick lawn grass, you can discourage its growth by cutting it at the proper height.

Deep watering your lawn is the another method to kill crabgrass. This will further strengthen the roots of the grass thereby giving less chance for the crabgrass to spread. If shallow and frequent watering is down, it can encourage crabgrass to thrive as they grow best in harsh conditions.
