crabgrassHave you noticed crabgrass growing in your lawn? Crabgrass is not harmless and should be treated promptly.

Crabgrass is considered to be one of the most stressing lawn and landscaping problems for every homeowner. Apart from it can outgrow beautiful lawn grasses, it can also be highly poisonous to your garden plants.

Because of the numerous seeds that crabgrass has, it is easier for it to multiply. They quickly germinate as the temperature starts to rise more than 55 degree Celsius, and sunlight begins to reach the moist soil. Also, the bare spots they leave are an ideal place for them to germinate more seeds.

Although commercial pesticides are effective on getting rid of crabgrass, it can harm your pets and children. Instead of chemical-based products, you can try the following solutions.



Seed distribution allows crabgrass to spread in a larger area which can dominate your lawn. One of the best ways to eliminate crabgrass without the help of chemicals, is to prevent seed distribution. When you pick grass from the ground, place in a plastic bag and throw these bags immediately into the trashcan or landfill.

Apart from discarding the crabgrass, you can tie up the bags and leave them under the sun from 4 to 6 weeks. The heat will kill the seeds, and provide the best time to compost them safely.


To solarize the soil, during the hottest months of the year, mow the lawn leaving it at a short length. Then, generously water the area and cover with a transparent plastic sheet. Seal the edges and dig a shallow trench. Next, cover the perimeter of the plastic using soil. You can leave the plastic covering up to six weeks to heat the ground helping to kill the seeds.


Crabgrass can quickly germinate if the lawn is not densely shaded. A healthy and thick lawn will protect the area against crabgrass. Plant during fall for healthy grass, and when colder weather comes, the freezing temperature can kill the crabgrass seedlings.

When watering lawn grass, perform it deeply but in an infrequent manner. This is because when the soil surface dries, it results in killing the deep-rooted crabgrass. Also, you can set the mower above the recommended height range of particular lawn type, and as a result, the crabgrass will find it hard to outgrow your lawn grass.

Crabgrass can be a significant problem if left unattended. Keep your pets and family safe from chemicals by trying the methods discussed above, all while maintain a beautiful lawn.
