weeds

Are you struggling with weed growth on your lawn, in your garden, or in your vegetable plot? Let’s explore some of the most common weeds found in Eastern Ontario and the most effective treatment options:

Chickweed

What: Cool-season annual plant with small white flowers.

Where:
Most commonly found on thinning lawns or after topdressing. It can also be found in areas with moist soil and good sun exposure.

How to treat: Begin with hand weeding. Spray Fiesta or Weed-B-Gone (available at our garden centres). To eventually crowd out chickweed, you can overseed the lawn.

Lambs Quarter

What: Annual weed. Lambs Quarter can reach 1.5 m in height and spread to a width of 40 cm.

Where: Grows in bare loose soil or tilled soil such as vegetable plots and gardens.

How to treat: Hand weed, mow (if on a lawn) and apply a spot treatment such as Scotts Pathclear (available at our garden supply store).

Purslane

What: An annual succulent with red stems and clustered leaves.

Where: Often found in loose soil, appears after rototilling or cultivating. Can be found anywhere in the yard independent of soil conditions.

How to treat: Hand weeding and mulching.

Canadian Thistle

What: A perennial plant that can grow to 1.2 m in height and 60 cm in width. Bull Thistle is similar, and has the same control conditions.

Where: It survives a range of moisture conditions and soil types.

How to treat:
Hand weed, but be careful because of the spiked leaves. Apply a spot treatment such as Scotts Pathclear, and then treat areas with Fiesta or Weed-B-Gone.

Dandelion

What: A perennial weed, very common and recognizable by the yellow flower head.

Where: Lawns, gardens, ditches, and fields.

How to treat: Begin by hand weeding, then apply Fiesta and Weed-B-Gone. Overseed to crowd out the weed for the following season.

Creeping Charlie

What: A perennial, evergreen creeper, Creeping Charlie is a very difficult weed to control.

How to treat: Hand weeding, apply Fiesta or Weed-B-Gone, overseed in the spring and fall.

Crabgrass

What: Annual grass, reseeds and dies back with the frost each fall.
