Most Common Weeds

1. Crabgrass

Crabgrass is an annual grassy weed that grows on your lawn and garden at the height of about 18 inches. It has fibrous roots, and as the name suggests, it’s a common weed from the grass family. It makes the soil more compact, therefore, interfering with proper drainage.

To control crabgrass, you can mulch, use pre-emergent herbicides or pull by hand the already grown crabgrass in your lawn and garden.

2. Canada thistle

Canada thistle thrive well in soil with low fertility. They have long roots and broad, rough leaves with needles. To control the Canada thistle, you need to improve your soil fertility by adding cover crops which helps in adding organic matter to the soil, and make your lawn more resistant to these opportunistic common weeds invasions.

3. Dandelions

Dandelions is a broad-leaf perennial weed that grows up to 12 inches tall. It has a very strong taproot. You can easily identify it on your lawn because it has yellow flowers which mature to puffballs and deeply notched leaves.


Another feature of these common weeds is that they have parachute-like seeds that are easily blown away by the wind. To control Dandelions, you can pull them by hands, use pre-emergent herbicides, do regular over-seeding and mulching.

4. Garlic Mustard

To control Garlic Mustard, you can pull them by hand or snip the bud. It’s advisable to pull and uproot everything thoroughly as they can emerge again if not well uprooted.

5. Dodder

The Dodder weed is commonly referred to as the strangle weed because of how it strangles other plants. The host plant grows into a variety of smooth branches which suppresses themselves on other plants, thus, lowering their growth rate.

To control dodder, cut the mother plant completely but carefully to ensure that you don’t allow the seeds to drop in the soil because it spreads by the seeds.

6. Bindweed

Bindweed is one of the common weeds that you will come across in Canada. It’s a broadleaf perennial weed that has arrowhead-shaped leaves and climbs 6 feet and more on other plants.
